Auction Market Theory for the Trader
A theory gives structure and pattern to the data.

Introduction
When you know, and know that you know, confidence replaces fear.

Every trader has, at one time or another, benefitted from a surprisingly fast, good trade. We immediately begin asking ourselves "should I take what I have and run, or should I hold in hope of additional appreciation?". Our next thought usually is: "I wish I knew what the market is telling me".

Traders are slaves to the practical, how to make winning trades. "Theory" often seems esoteric, the opposite of practical. That is not the case here. Theory is needed to tie the myriad loose ends of market data together, to organize and simplify market analysis. Auction Market Theory takes the entirety of market data and information and compresses it into a set of assumptions and rules. The resulting structure permits the trader to understand the migration of value and the market's condition within which the value change is taking place. This knowledge answers the "what is the market saying" question.

Value is the dominant variable in markets. Demand drives value. Change in value reveals demand. Read a market's value path and you can make reasoned and reasonable trading decisions. Auction Market Theory is your guide. It is based on observable facts. Facts lead to conclusions; to consistent, intelligent trading strategies.

A trader is interested in two things: when is a trend starting and when is it ending? In Auction Market terms the question is when does value begin to change and when is the value change over? Value is tracked with the Market Profile and integrated by the Overlay Demand Curve (two market structures that are explained below, see figures SC 2 and SC 7). In this article we will first develop the theory to get a clear picture of general market structure and let that knowledge guide our market analysis. Then we will apply the theory to develop trading strategy, including risk. The process is illustrated by walking through a real world example. Within the theoretical framework, Market Profile and Overlay Demand Curves alone are adequate to develop trading strategies. Additional auction market structures can buttress and augment those strategic decisions.

Auction markets have a price-based bid-ask format. Price and value are only loosely related. Price traces the activity, but value reveals the meaning of the activity. Time is the arbiter of value. Track a market throughout the day and you will note that some prices occur infrequently (highs and lows) while prices in the middle of the day's range are traded again and again. The middle prices are a region of high volume (and hence time) per price tick. Middle prices are the winners of the day's popularity contest. Typically, the distribution of price over time, i.e. volume, maps out a bell shaped curve. Heaviest trading is near the central price, smoothing out to low volume near the high and low. Prices around the center are the ones traders see as 'fair', where they perceive value; where the overwhelming majority of trading occurs. The bell shaped curve of price and volume describes a Market Profile.


Market Profile Defined

A Market Profile is a graph of one day's trading with price on the vertical and volume on the horizontal. It is a price-volume distribution chart. J.P. Steidlmayer defined the Market Profile in 1986 (Markets and Market Logic by Steidlmayer and Koy). Market Profiles convert one-dimensional price data into two-dimensional value data (see figure SC 2 of paragraph B). The advantage of the Market Profile over other intra-day data displays is that you can watch value build as the trading day proceeds, knowing that the 'fat' part of the price-volume display is where your fellow traders, i.e the market, locates fair prices. Market Profiles build 'day timeframe' information.

The middle seventy percent of the distribution is named the 'value area'. In an ideal bell curve the value area is approximately one standard deviation above and below the center of the distribution, that is the central seventy percent of the activity. Value, then, is a group of prices, not just one.

Figure SC EX-1.  Market Profile for Soybeans March 00, Dec 30, 1999.
The letters D, E, F, G,... identify trading in particular timeframes 
(D is 9:30 to 10 AM).  At 4690 trading occurred in five different time
periods).  Value area contains seventy percent of the TPOs (see figure 
SC 1 and below for TPO definition).  (Price 4690 is shorthand for
$4.69 cents per bushel of soybeans.)

Price ranged from 471:0 to 4650.  Value Area is 4702 to
4680.  Center of the day's distribution is 4686.  Relative volume 
is in the letters, the TPO's.  There was five times the volume at 4686 
as at 4710 or 4650.

A brief analysis of the market from the profile:
1) The open was quickly rejected by the market at 4654 (9 - 9:30 AM)
2) The Low was immediately rejected by the market 4650 (9 - 9:30 AM)
3) Price traded most of the day within the value area 4702 - 4680
4) The high at 4710 was immediately rejected by the market (12 - 12:30) PM
It is clear that the market accepted (as value) prices in the 4702 to 4680 range and did not much value prices outside that range.

Day timeframe data are immediately useful. Imagine you are a day trader tracking a market's profile at midday. You know: 1) the location of yesterday's value area, 2) today's value (so far) and 3) where today's value is, relative to yesterday. The fact is, you now know a great deal about the market you are trading. Any trading decision you make will be aided by your knowledge of value.


Comparison of Market Profile with a Candlestick Display
In the Japanese Candlesticks technical method, the basic element is a cylinder with open and close as limits; with the high and low spiking above and below the open/close base. The candlestick form for the Market Profile above looks like:

                         |        high    4710
                         |
                       -----      close   4686
                       |   |
                       |   |
                       |   |
                       -----      open    4654
                         |
                         |
                         |        low     4650

Figure SC EX-2.  Candlestick representation of Figure SC EX-1.

The prices most utilized by Candlesticks, the high and low, are just the ones least valued (traded the least) by the market. Likewise, the open, in this case, was also quickly rejected, but was used by Candlesticks to form a base.

As with the Market Profile, Candlesticks would combine this day with others to develop trading decisions. Value, not price governs. Candlesticks is using price, i.e. poor, non-representative data in their construction. Every day's high and low are those prices least valued by the market. Trading decisions taken on the basis of poor data are unlikely to prove to be good predictiors of the market's future path or even provide a reasonable picture of the current market situation.

Candlesticks is a closed, fully defined system and can be investigated completely. Giovanni Maiani, S&C Nov 02, p60, has done so. In his words "The most reliable, long lower shadow, present 1.9% of time, anticipates a declining session 49.12% of time, rising session 40.61% of time. For traders who are quantitaively based, candlestick patterns are not terribly useful"

Steve Nison, the creator of Candlesticks, responded (S&C Jan 2003, p74) that Candlesticks are "A tool, not a system", and that you need to know the trend to use them. We feel that if you know the trend there is little reason to use something that we, at least, would use to find the trend.



Overlay Demand Curve Defined

A year or so after Steidlmayer's book, this author developed a longer term profile by linearly combining several days of Market Profiles. The new display, an Overlay Demand Curve, tends to integrate out the noise inherent in each day's Market Profile. The resulting multi-day price-volume distribution now shows 'market condition' (see figure SC 7 in the section "Development of an Overlay"). That is, you can tell from the Overlay whether the market is in balance (single distribution), breaking out of balance, trending or moving back into balance (congesting). Overlays with different time frames (5 days, 10 days, 20 days, etc.) give a panorama of recent market value development. Combining knowledge from the profiles and Overlays provides a detailed view of market behavior on both day and longer timeframes. You can see where the market has been, where it is and where it is recognizing value. This is the information needed for quantative trading decisions.

Longer timeframe information, i.e. market condition, is the foundation for all subsequent analysis. If the market is in balance, you know exactly where price will exceed the balance (for both upside and downside breakouts). Swing /position traders are alerted to the potential start of a trend at the breakout. Further, the range of the balance region, coupled with the bell shaped curve of the price - volume distribution, estimates trading risk. Day traders get a directional cue from the balance. They should look to be a short seller of downturns near the top and a buyer on upturns near the bottom. On breakout, the daytrader knows to switch, and to now trade in the direction of the trend (e.g. seeking local bottoms in up trends).


Auction Market Theory

Auction markets have a number of identifiers (ticks, highs, lows, time of events, etc). Theory compresses the data into a small number of theoretical assumptions, converts price to value and sets rules for analyzing the market. With the theory comes a more generalized and simpler view of markets. Most any type of auction market behavior can be analyzed. Even if the theoretical model does not fit the data exactly, it is still useful to describe the situation. Trading strategy flows directly from market analysis.

Identifiers and Observables
1) Markets have a place (exchange, computer) and structure (members, clearing) for doing business with defined rules and oversight or regulation. They also set margins based on risk.
2) Auction prices are arrived at by negotiation
3) Some prices are accepted (value), some are rejected
4) In balanced markets, both Market Profiles and Overlays are bell shaped
5) A market may be balancing, trending or be in between the two phases
6) Participants may be oriented to the short time frame (day traders) or longer timeframes (swing traders)
7) Trader's opinions determine whether the market will be active or quiet
8) Markets display little day-to-day serial correlation
9) Markets cycle from balance to trend and back
10) Individual market cycle phases may be short or long
11) Exchange members perform numerous functions on the floor
12) Larger traders make strategic trades ("if you want to buy 1000 contracts, first sell 100")


Auction Market Knowledge:

Markets report activity in terms of price and volume. You trade in price units. But demand is driven by value. Clearly, it is necessary to convert trading units from price to value if the analysis is to proceed. Price to value conversion is made via Market Profiles and Overlays. While value is the dominant variable, trading involves a number of other factors noted in the Identifiers and Observables table above. These factors can play a critical role in trading success.

A) Exchange Trading Hours Affect Price and Volume:
Overnight order accumulation creates a backlog at the opening. Thus prices are distorted early in the day. In most markets there is an 'opening range'. Likewise, day traders and others exiting near the close are responsible for a 'closing range'. Typically, members can assign any price in the opening or closing range to a trade made for a customer.

Exchanges, or clearing authorities for some electronic exchanges, interact with the public principally in setting margins. Margin is 'earnest money' guaranteeing the broker we deal through that we will cover our losses. Our interest in margins in part is the amount of money we must deposit in order to trade. Far more important is how the exchanges set margins. With a lot of experience backing them up, the exchange margin is set to mirror the risk. Our trading models inevitably have a risk function of some sort. However, anytime we see the exchange margin being changed, we should look to our methodology to be sure we are recognizing a change in the risk we are taking. Since exchange margins are not necessarily what your broker charges you (brokers often charge more), keeping track of exchange margins takes some effort.

B) Prices are Set by Negotiation:
There is a buyer and seller for each contract traded. In the price- volume figure SC 1, price auctioned up to 6054, above which there were no bidders. Also, during the day, price went as low as 6036, below which there were no sellers. In between, there were many buyers and sellers.

Figure SC 1.  Swiss franc volume by price.  Minimal trading occurs
at the top and bottom prices.  The three top and three bottom prices have
only 3 percent of the day's volume.  The middle six (6042 - 6047) have
70 percent of the trading.  The disproportionate volumes at 6045 and 6047 are
at least partly artifacts of the way orders are placed (e.g. five is a popular 
trading point, diminishing the six next to it).  Volume data is from the
CME Liquidity Data, with volume in 'sides' (two sides = round turn).

With no idea of when the trading at a particular price took place we would be hard pressed to tell from figure SC 1 just when we might have traded at that price. That is not much of a problem in a congesting market, since there are many opportunities at all the prices in the value area.

Recasting the price - volume plot into a Market Profile and a half-hour bar chart adds a substantial level of information. The half-hour bars are identified by letters; y, z, A, B,..., where each letter signifies a time span. The y's are for the period 07:00 to 07:30, z is for 07:30 to 08:00, A is for 08:00 to 08:30 and so on. The letters are called TPO's or time-price-opportunities. Collapsing the bars to the price axis creates the Market Profile. TPO counts are commonly used in place of actual volume since they embody both price and time.

Figure SC 2.  Swiss franc Market Profile.  The price - time distribution
is quasi-bell shaped.  TPO volume peaks in the middle prices
(6050 to 6040) and then tails off toward the upper and lower limits.  There 
is very little support for trading at the highs and lows of the day.
The highs and lows are rejected.  Prices in the middle are accepted.


The 70% region (value area) is 6049 - 6040. Value area calculation starts with the 'point of control', the price with the most TPO's (6047, in this case). Then add the next two highest and so on until 70 percent of the TPO's are included.

C) Accepted Prices and Rejected Prices:
Prices between 6039 and 6050 traded heavily. You could have traded at 6044 many times within the day. Had you wanted to trade at 6054 or 6036 you would have found little opportunity. Accepted prices define value for any particular point in time. So value is a product of price and time. The most accepted price is 6047. That price traded in all but three of the fourteen time frames.

D) Auction Markets in Balance Map Out Bell Shaped Price - Volume Curves:
Many of our life experiences are described with bell shaped curves. Distributions as widely diverse as the heights of men and the batting averages of baseball players display the bell. Markets do too. The bell shape is useful in defining value, market condition and in determining risk. In short, the bell curve concept is invaluable in understanding the market, even though the Market Profile and Overlay distributions are not perfect 'normal' distributions.

E) A Balanced Market:
The market of figure SC 1 is in balance for the day (single bell shaped curve). It is said to be accumulating (i.e. congesting). The high - low range is relatively narrow, attesting to an only moderate interest level on the part of the traders.

Figure SC 3.  Swiss franc volume by price.  October 29 is the next trading day 
after October 26 of figure IDO 1.  The trading range is twice as large and
the orderliness of IDO 1. has disappeared.  Volume today is 12,844 compared
to the much lower 2,574 of yesterday.  This market has moved over $1,000
in one day (close to close).  Volume data is from the CME Liquidity Data, 
with volume in 'sides' (two sides = round turn).

Monday, October 29 (figure SC 3), is quite different from Friday. The range is wider. This day has two distributions, 6106 to 6122 and 6122 to 6143. Obviously, there was activity in the overnight market because of the gap (Swiss franc does trade throughout most of the 24 hour day). Of importance to day traders, is that this market has directional movement. It may offer trading opportunity. The direction and amount of movement is readily apparent in the Market Profile in figure SC 4.

Figure SC 4.  Market profile for SF on October 29, 2001.  A trend day.
The volume profile, figure SC 3, shows the same general structure, but
the market profile shows timing within the movement.  Overnight trading
in the intra-bank market moved price upward as noted (from about 6050 to
the 6114 region).  For the first three periods the market accepted 6114
as the new balance.  But this was merely a pause, not end-of-trend.
The next jump in B period (8:30 - 9:00) found a new balance around 6133.

Also, trading opened on Monday well above the value of Friday. Each market day will find it's own characteristic value. Each day will have it's own news, rumors, power plays and the like. Consequently, value will fluctuate from day to day. In a balanced market the fluctuation is bounded. If the market it trending, day to day changes in value are unbounded. The bounds are determined by the Overlay Demand Curve (see "Development of an Overlay" below). An example of Market Profile variation in a bounded environment is figure SC 6.

F) Demand: Day Traders and Swing/Position Traders:
A (day) trader who is out of the market by the close generates no lasting demand. One who holds for an extended period does create demand. Within a day, the local-member may be in and out fifty times, long or short with equal probability. No demand created there! Public traders often act directionally. They buy and hold. Their actions are often due to chart formations (with which the members are also familiar!). Within a day, the public can drive prices away from the balance so prized by members. If the public is successful, a trend begins. More often we fail, leading to an aborted trend or a failed breakout which quickly crumbles. (Commercial members often have quite a lot to do with the failure, called commercial capping. Capping is discussed in detail in the text Value Based Power Trading, pg 33 - 47).

G) Trader's Opinions Govern Market Activity:
Public traders make money only by capturing a non-equilibrium market move, a trend. Volatility is a must. Trends are driven by a fundamental change in demand. But one rarely knows or has information on the driving fundamentals. Rather, your measure is change in value. That you can track. Collectively, traders opinions create demand. The auction market trader gains an opinion from value change. For example, the Swiss franc of Friday has value centered around 6045. Monday opening at 6114 is way, way above previous value. We ask ourselves, "is this the new value?" "Did I miss the whole move?" That question is answered when price breaks out of the y-z-A congestion in B period (8:30 to 9:00 am) at 6120. There is still additional demand driving the market. There is opportunity for the day trader.

H) Markets Display Little Day-to-day Serial Correlation:
We know from observation that even in long term trends the probability of tomorrow being higher (or lower) than today is close to fifty percent (see example in Value Based Power Trading, pg 19 - 24). Today is therefore not a good predictor of tomorrow. So what does auction market analysis use for predicting future price? Nothing! Absolutely nothing! Auction market analysis makes no projections. Rather, we learn as much as we can about the current market situation. Then, we trade off the changes. We know when today's value moves relative to yesterday. We know when yesterday's balance breaks out. The market is showing its motivation by its behavior relative to value and market condition.

I) Markets Cycle from Balance to Trend and Back:
We do know that the market in balance today will trend sometime in the future. The next step from balance is a breakout (really, an alert that a trend may be starting). On a Market Profile that alert is often seen as a series of single prints as the B's from 6120 to 6124 in figure SC 4. The alert may stall before a trend gets underway, resulting in a 'failed breakout'. Or, as in SC 4, a trend does begin; in this case running up to 6138 within the single half hour B period (8:30 to 9). The end-of-trend transition is sometimes marked by a reversal, but more often by congestion. Continuation of the congestion leads ultimately to a new balance. Both stages are present in figure SC 4. In B period we had the nice run to 6138, a reversal back to 6131 in C period and then congestion the rest of the day. The B period run is exactly what day traders seek. Since we know the phases of the market, throughout the run we are watching for either the reversal or congestion signaling the onset of the next phase (transition back to balance). The form, Market Profile/half-hour bars, combined with market knowledge gives us the ability to see deeply into the market process.

J) Market Cycles may be Short or Long:
The trend in the example took place within one half hour period. At another time a trend might last several periods or several days. Market knowledge tells us the order but not the time or the magnitude. We can be sure that a trend will end and ultimately move into a balance. But we have little information on how far the trend will go or how long it is until the transition begins. We do not need to guess. The market will tell us. We just need to be alert to the tell-tale signs of reversal and/or congestion.

K) Exchange Member's Functions:
So far we have equated market knowledge to an understanding of value based data displays. A market is also comprised of people, us and the members and/or professional traders. Four classes of members inhabit the floor. We must interact with them. It is to our advantage to understand their motivation. Class 1 are the Locals or scalpers, the other side of virtually every transaction. They work for themselves, provide liquidity and are most comfortable with balanced markets. Class 2 are the commercials who's job is to trade for their companies. These are the businessmen of the floor. Their company will be a large commercial firm, e.g. Morgan Stanley. Since commercials know both the cash and futures markets, they are the best informed traders on the floor. They too work best in balanced markets. In addition to their "business" they may speculate when prices are out of line (the capping mentioned in paragraph F). Commercials typically do five to fifteen percent of the volume. Class 3 are members clearing for other, off-floor, members. This class accounts for around five to ten percent of the volume. Lastly, Class 4 clears for us, the public. We, the public, are typically twenty to thirty percent of the day's trading volume.

Column headings:  Price, Volume (in half contracts), %Volume for
each price, %CTI1 is volume percentage for the local members, %CTI2 is
volume percentage for the commercial members, %CTI3 is volume percentage 
for the off-floor members and %CTI4 is members acting for the public.
On the far right, BRACKETS refers to the Market Profile.

Below the volume table, totals show the average percentages of volume for each of the four member classes. 70% Volume Summary is the volume value area. Point of control for the volume is the high volume price, 10630. Below that is the TPO value area, with point of control (peak TPO price).

T-bonds are quoted in 32nds. The price 10708 stands for 107 and 8 32nds. The next price tick above 10631 is 10700. A move from 10600 to 10700 is $1000 for the one unit jump. A move from 10621 to 10622 is one price tick, worth $31.25.

Liquidity Data Bank reports are a more comprehensive version of a Market Profile. The value area is defined by trading volume as opposed to using the TPO's in SC 2. (T-bonds trade in 32/nds, 10708 is 107 and 8/32nds, where one 32nd is $31.25.)

L) Trader's Strategies:
Trading is a 'me against the rest of you' situation. In a zero sum game (no fees and commissions) the losers buy the winners beer. Mis- direction is a valid strategy. The old saying "if you want to sell a thousand contracts, first buy one hundred" illustrates a strategy. By making others believe the market is taking an upturn, it becomes easier to sell a large holding. If we understand the value situation, that the buying of the hundred was done without any apparent change in value, it is easier to avoid such traps.

You now have the, mostly, day time-frame, facts of auction markets. With practice you can use these facts to trace the evolution of value throughout the day. You can usually answer the question "what is the market doing".

Something is still lacking in developing a trading strategy. It was alluded to in the brief discussion of longer timeframe information. If we know the context of the current market situation, the market conditon, we are able to set our strategy. Yes, a day trader should behave differently in balanced markets and trending markets.


Auction Market Knowledge: The Longer Timeframe

Let's start by reviewing two important facts: markets are not correlated on a day-to-day basis and markets are in a continual cycle. The lack of correlation precludes finding market condition from yesterday's market. But we need to know the condition for all directional trading decisions. Enter the Overlay Demand Curve.


Development of an Overlay:

First, look at five sequential days of Market Profiles in figure SC 6. The display appears for all the world like three days down (3/16, 3/19 and 3/20) and then three days up (3/20, 3/21 and 3/22).

Figure SC 6.  Five sequential days of Market Profiles. 
US T-bonds, March 16, 2001 through March 22, 2001.

If we simply sum the five days, the longer term view is one of balance! The five day Overlay in figure SC 7 shows a roughly bell shaped curve with upper and lower distribution limits at 10706 and 10528. The close of trading at 10628 is well within the balance.

Figure SC 7.  Five Day Overlay Demand Curve of June 2001 T-bonds 3/16 - 3/22.
The label L/F gives the range of the earliest day (5) and the most recent 
day (9).  The Rotation Profile (ROT PROFILE) is the range for each of the 
five days presented in Market Profile form.  It allows the relative dates 
of trading to be resolved.  In this case, the 9's show the latest day's
trading to be near the top of the 5 day distribution.  Distribution limits
are at the last price before the TPO's fall below three.

What happened? For one, our eye fooled us. This often happens with graphical data--our perception is colored by differences rather than similarities. The best known cases of this is with chart formations (head and shoulders, Elliot waves, fibonacci numbers, candlesticks, etc.). Also we often cannot pick the details out of the overall picture. In figure SC 6 the centers of value and value areas are:
          CTR      VaU      VaL
  3/16  10611    10619    10606
  3/19  10608    10611    10605
  3/20  10602    10604    10529
  3/21  10612    10617    10609
  3/22  10700    10705    10625

The earliest four days have a mean value of 10608 for the center. The average deviation is only 3 ticks. The market of 3/22 does not seem to fit. We will use auction analysis later to explain and understand that large deviation (23 ticks).


Market Condition from Overlays:

As traders, we speak colloquially of market condition. Is the market trending? Is the market unusually volatile? Has it crossed a resistance or support price? And, of course, what path do we expect the market to take? These descriptors are pretty qualitative. Trending implies a time frame. A market may be trending in the twenty day period but quite balanced in the last five days. Bar chart support/resistance points are historical and rarely tied to current market activity--ultimately current activity may provide the next set of support/resistance points, but that rarely helps our decisions of today. Predicting a market's future course would at least imply a knowledge of the current market condition. However, technical analysis and/or chart reading really says very little about the current market situation. The writer has caught sharp moves that grow open trade equity very fast, as noted in the opening paragraph. A pause comes. The technical indicators are strong, but that is to be expected and helps little. The dilemma is: run with our profits or stay in the hopes of more? Truly, a weak trader is easily recognized by leaving a good move too soon. That is not the case: here it is a question of will the good move get better? If one can determine market condition, the problem is resolvable.

Market Profiles track value from yesterday to today. They do not give the context for any longer timeframe. This comes from the Overlay. Refering to figure SC 7, we see that at the end of 3/22 the past five days action is described as 1) a single quasi-bell shaped curve with the closing price inside the distribution. In short, on a five day basis, the market is in balance. If the distribution is defined to terminate on three TPO's (approximating the +/- two standard deviation, 95 percent confidence level of the 'normal' distribution), we find the upper limit of the distribution at 10706 and the lower limit at 10528. Reasoning from the 95 percent confidence concept of the normal distribution, we find that prices above 10706 have a good chance of not belonging to the five day balanced distribution. That is, price above 10706 is a breakout, the potential start of a new (trending) distribution.


Calculating Risk


The Overlay range is a measure of a market's activity. Range is related both to volatility and to trader interest in the market (which usually increases volatility). Volatility is equated directly to risk in the stock market. But it is not the whole story in active trading markets. Trader interest is triggered by outside events, say a currency devaluation. That brings more traders into the market and hence more volume at each price; more prices that are tradeable (increased range). So range is one place to look for a risk measure.

The other aspect of range depends on the Overlay's relationship to the bell shaped curve. From the middle of the range to the upper limit is two standard deviations. Same for middle to lower limit. The total range is four standard deviations. So, one standard deviation is very roughly one-quarter of the of the range, or 10.5 points in figure SC 7. Experience shows that this type of risk varies from about one-eighth to one quarter of the range (half a standard deviation to a whole one).

Figure SC 7 has a 42 point range for the 5 day Overlay. At $31.25 per point, that is $1312. If an upside breakout occurs at 10707, what would be a good trading risk? The quadrant (one quarter of the range) is 10.5 points or $328, half of that is $164.

Risk generally depends on the type of trading, more for swing (overnight) trades and less for short term day-trades. In this example the swing/position trader should risk over $300 to not be stopped out by market range volatility. A day trader has a much shorter time horizon, with a commensurately smaller risk of around $150. Risks derived from the Overlay range offer a starting point, a logical rule of thumb, for risk analysis.



Volatility
Volatility is a natural part of all auction markets. It is related to the trading range; small in quiescent periods, larger in more active markets. It changes from day to day. Fluctuation grows with volume (demand) in the day timeframe. Daily trading range gives a gross estimate of market fluctuation.

A better working estimate of volatility describes activity within the day. Market Profiles are based on half-hour periods. Half-hour timeframes break down the day into manageable parts. More importantly, a half-hour appears to be the minimum average time for changes in demand to be reflected in value. This was the original reason for selecting the half-hour timeframe.

We define the (AMT) volatility as the average range of the half-hour time periods of a Market Profile. In figures SC 9 and SC 10, these are:


                       y  z  A  B  C  D  E  F  G  H  I  J  K  L   Average
           March 21    8  8  6 10 12  4  6  9  6  8  5  6  7  6     7.4

           March 22    4  8  7 12  9  7 17 11 10  9  7  7  8 11     9.1
                       
The average of the half-hour bars approximates the risk of a trade stop-out from either the long or short side. It is the 'fluctuation' risk. If one sets a risk (stop-loss) smaller than this noise, then the probability is high that simple market fluctuation will cause trade exit. The volatility, then, sets the minimum risk for a trade.

Practically, volatility has another important use. It is a sensitive measure of market congestion. Balanced markets (congestion) tend to have low volatility. Trending markets have larger volatilities. March 21 is clearly congesting, as observed in figure SC 9. March 22 (figure SC 10) is a combination trend (periods y through F) and congestion (periods G through L). The 90 day average volatility for T-bonds (as of March 13, 2002) is 8.3. Minimum is 3.9 and maximum is 15.5. Assuming about the same range in 2001, both March 21 and 22 are near the average. Very large volatility increases rarely precede the start of a trend, although often the general market tenor, as measured by volatilty, rises prior to directional movemant. Volatility helps to uncover trend end. In the table below, volatility offers a tip-off to market intentions. The 90 day average volatility as of March 18, 2002 is 376. High is 880, low is 200.

Table SC-T1.  S&P emini March 2002.  Market demand interpretation
aided by the volatility.  BAL is 5 day balance as discussed in the
Overlay Demand Curve section.  ULIM and LLIM are the Overlay balance
limits.  VTY is the half-hour bar average range volatility for the day.

  Start with the Balance as of close Jan 28.

  Jan 29, breakout on down side alerts for start of trend.
  Close of Jan 29: Price lower, volatility at 546 is up 80 percent.
    Interpretation:  volatility implies demand is still present.
                     
  Close of Jan 30: Trend bottomed out at 108075. Closed higher.
    Interpretation:  short timeframe trend is over.  Higher volatility
                     is not directional and is thus disregarded.

    This short run from Jan 29 11 AM to Jan 30 11 AM is confirmed by
    the volatility of Jan 30, but not until end of day.  By that time
    the move was over.


  Start with the Balance as of close Feb 4.
  Feb 5, breakout on down side, volatility up 30 percent, price lower.
    Interpretation:  short timeframe trend is probably still in place.
    Volatility confirms the move.

  Feb 6, price moves down slightly, volatility is only 27 percent above entry.
    Interpretation:  demand or trader interest is not growing.

  Feb 7, price continues down, volatility is down to 22 precent above entry.
    Interpretation:  demand continues to decay.

  Feb 8, local bottom reached at 107550, close is higher, market in balance,
    volatility is back where it started from.
    Interpretation:  trend is over.

  Start with the Balance as of close Feb 8.
  Feb 11, breakout on the upside, close at breakout price, volatility lower.
    Interpretation:  breakout not supported by demand increase.  In the
    following days price continued strong and volatility grew.  On Feb 15
    a new balance was reached at the higher price level.

  On longer moves, the volatility tends to strengthen.  End of day volatility 
  is important to the longer timeframe (swing) trader, less so to the day
  trader.

                       


Volatility is another valid way to check markets for demand. As reference point for market condition, volatility adds to the visual measures discussed in figures SC 9 and 10.

Volatility calculations are tied to the timeframe. If a different timeframe is selected (say 15 minute bars) the volatility will be unique to that timeframe. However, the only valid volatility is the one associated with the appropriate timeframe, the timeframe that best reflects the time delays inherent in the market. That timeframe is thirty minutes in the data in this report.


Auction Market Theory Reviewed

Why Auction Market Theory? The short answer is that it gives us auction market analysis for devising trading strategy. The theory isolates the individual pieces of a market and integrates them into a whole. We know the effects of exchange hours, how auctions behave in seeking both too high and too low prices to locate value, and the fact that normal trading builds bell shaped distributions. We know how to find value and market condition. In a run, we know the importance of congestion in recognizing trend end. And we can use market cycling to prepare for the next breakout or trend end. Lastly, we have a feel for members intentions. In short, taking the facts about auction markets and applying them to any particular market situation guides us in developing our strategy from that point on.

Is Auction Market Theory a trading model? No. A trading model has most market parameters pre-chosen, built into an algorithm. Given a particular price structure, a model will follow the same path regardless of internal market conditions. A strategy is different. Strategy comes from understanding the market situation as it relates to us, to our unique needs and desires. We have general rules but a wide latitude for action. For instance, a day trader active in a balanced market who knows the upper and lower limits, will seek to sell downturns near the upper limit and buy upturns near the bottom. If price breaks out of balance on the upside, strategy changes to buying upturns only. Market condition sets the strategy. But the trader selects action points and risk.

Presumably we could build a trading model for our own trading style. Such a model would have more in common with an 'expert system' than a technical model. An expert, one who is familiar with auction markets, knows how to marshal the available information and data, when faced with an unfamiliar market situation. The expert needs information rather than a rigid model that makes a rigid decision for any market situation. Really, this is no different than the way a good company CEO acts.

At the end of a trading day we are faced with the decision of how to trade tomorrow. A swing/position trader will first attend to the trades that are still on. A day trader will presumably have no current trades. For this example we assume no positions left over at the close of March 22.

Our general approach is to collect the information available on value and market condition. These data will include the latest day's behavior and at least the market of the day prior. Then we factor in what we know from the theory of markets. Lastly, we set our strategy for the next day. Both day and swing traders start their analyses at the same place--with the market condition.

Market Condition at the close of March 22 from figure SC 7 is:
MC1) Market in 5 day balance, with limits 10706 and 10528, close 10628
MC2) Balance is skewed toward the top
MC3) Latest day trading (L/F = 9) concentrated at upper prices

From the previous 5 day Overlay of March 21 in figure SC 8:
MC4) Market in 5 day balance, limits 10626 and 10527, close 10611
MC5) Balance is symmetrical
MC6) Latest day trading (L/F = 9) mostly above the midpoint

This balanced market preceeded the breakout day 3/22.

Conclusions from Market Condition (MC) behavior:
MC7) On March 22 the balance broke out on the upside but did not hold
MC8) Price ran up to 10708 (14 ticks = $437), then pulled back to close at 10628, a sign of weakness
MC9) At end of day, market is back in balance (is this a failed breakout?)

TD1) Swing trader will go long above 10706 or short below 10528
TD2) Risk will be around $325, the one standard deviation level.

Recall that the market condition provides the framework within which value based trading decisions are made.

Figure SC 10.  Market Profile for T-bonds, March 22, 2001.
After moving out of the y-z-A congestion the market struggled to
a top in F period.  From C period through the rest of the day
the market is congesting.

Conclusions from Market Value behavior:
MV6) Value is higher on the day, but got there early (B period)
MV7) Market showed congestion early, during first hour or so
MV8) Market spent last 5 hours in congestion
MV9) Except for the quick run in B period this is a congesting market
MV10) Value at 10705 - 10625 provide support/resistance for tomorrow
MV11) Price nearing 10705 (upper limit = 10706) is a warning of impending breakout
MV12) Price below 10625 is a sign of weakness

Trading Strategy (TS) for March 23, Basis both Condition and Value:
Note that all the information used is market developed. Also remember that market condition can change overnight as happened in the Swiss franc example. The trader reads the market and determines a strategy based on current conditions. Any substantial change will be obvious, requiring an upgraded analysis.
TS1) The market is in balance. Price above 10706 is an upside breakout Price below 10528 is a downside breakout
TS2) Risk on breakout for the swing trader is around $330
TS3) Risk on breakout for the day trader is around $160
TS4) Early congestion followed by massive later congestion on 3/22 is indicative of a market confused about underlying demand
TS5) A breakout tomorrow is unlikely because of the congestion picture in the last few market hours of 3/22.
TS6) This is a low priority market for the breakout swing trader
TS7) If tomorrow open is still in the upper area of the Overlay, day traders are looking to short any turndown. If prices reach near the bottom of the Overlay, we will seek to buy bottoms.
TS8) If the upper limit (10706) is exceeded, day traders change to looking to buy into upturns.
TS9) Upper Limit (10706) and upper value area (10705) are nearly coincident. Price there is strongly bullish.
TS10) Day traders turn bearish below 10625, seeking to short downturns.

Trading strategies TS1 through TS10 come from a direct reading of the auction market variables. Another seasoned trader may use the same data in a different way. The starting point is the same: trading on 3/22 began with an upside thrust, a breakout, and then traded down while congesting. The previous day, 3/21, ended in a much more symmetrical balance and that day's Market Profile was likewise quite normal for trading in a balance.

So 3/22 is a colossally failed breakout. Why? How soon in the day's development could a market savvy trader catch on? Congestion tells the tale. We are looking for that transition from trend to balance. We can recognize congestion graphically as in figure SC 10. But if we know more about markets, we have a chance to do some intelligent guessing.


Short Covering Rally

A common phenomena in markets is the 'short covering rally'. Conceptually, imagine that many of the local members on the floor end the day short, rather than the more usual flat. After a sleepless night, they come to work eager to exit. As professionals, they know better than to exit all at once. Each one is looking for an exit that hurts the least. Some trade immediately and some wait. The net is that the market sees demand over the period in which the members are buying in their shorts. This period is typically an hour or two. During the time the members are net buying, public interest is aroused. The public carries the price on up until they realize demand has evaporated. But this takes time. The market is not efficient. The TPO shape of a short covering rally is that of a capital P. Price runs up, stopping past the point where the excess demand is gone. Then there is a period of backing and filling, forming the loop of the P. Look at figure SC 10 again. Do you see the P?

Now we understand the overloading toward the upper prices in the Overlay for March 22 (figure SC 7). The upside breakout was likely driven by a short covering rally. It was merely an accident that the rally occurred near the breakout of the Overlay. Now we have evidence for the failure of the trend. No wonder the Market Profile for March 22 did not fit in with the prior four days.

Additional Market Analysis from Short Covering Data:
TS11) The odds are that the Overlay tomorrow will pull back, i.e. 10708 is a local high.
TS11) Unless new upside demand enters the market, the odds are that the Overlay tomorrow will pull back, i.e. 10708 is a local high.
TS12) Understanding the probable cause of the rise on March 22 does not substantially change our strategy for March 23. Corroboration adds confidence in the original analysis.


Buy/Sell Confirmation of the Original Premise for Short Covering


We cannot look into the minds of the floor traders. But often we can see what they have done. The Chicago Board of Trade releases an end-of-day Buy/Sell report. These data list the four classes of member's volume at each price and also how much of the activity is buying and how much is selling. The Buy/Sell Report for March 21 is in figure SC 11. For the Locals, CTI1, it lists the buying, selling and net for each price, and totals at the bottom. Floor traders indeed ended the day selling more than they bought by over 1000 contracts (2108 sides = 1054 equivalent contracts). Yes, on the 22nd, Locals probably came to work with latent demand and an itch to get out.

Figure SC 11.  Buy/Sell statistics for T-bonds (day), March 21, 2001.
CTI1, floor traders buy (b), sell (s) and net (n) volumes at each price
culminates in a net sell of 2108 sides (side = 1/2 contract).  The other
three classes of traders (CTI2 = Commercials, CTI3 = Off Floor Members and
CTI4 = Members Trading for the Public) show the net only.  Market Profile
symbols are Z = 07:20 to 07:30, $ = 07:30 to 08:00, A = 08:00 to 08:30.
B = 08:30 to 09:00 and so on.

Additional Market Analysis from Buy/Sell Data:
TS13) At the end of March 21 the Locals were net short 1054 contracts. Analysis for March 22 would suggest a potential net demand from the floor traders.


Commercial Capping

Paragraph F) mentioned commercial capping; the process where the commercial members (CTI2) sell heavily at the top (or buy heavily at a bottom) to push price back to balance. March 22 T-bonds moved up on demand that was exhausted at the top. Did the commercials aid the price drop? In figure SC 5 the CTI2 average volume for the day is 6.1 percent of the total. Going down the %CTI2 column we see the first two values of 14.7 and 8.7. Both are substantially larger than the average. The path of price in F period (10:30 to 11:00) is down from 10708 to 10630. Indeed, it appears the commercials capped and drove price well back to the middle.

Additional Market Analysis from Commercial Capping Data:
TS14) Commercial selling at the top indicates the public does not have enough buying power to keep the upward trend in place. Again, commercial data confirms analyses TS4, TS5, TS6 and TS11.


Volatility

Volatility from the half-hour bars is:
    5.0 for March 20,
    6.0 for March 21,
    8.4 for breakout day March 22
    5.0 for March 23
    8.3 for 90 day average.
It is clear that the action of March 22 was not accompanied by the sort of increase in volatility associated with increasing demand.
Volatility casts a vote for a false breakout.


Value Areas from LDB and Market Profile


The Liquidity Data report (LDB) in the CISCO format carries both the volume value area (VA) and the VA developed from the TPO's. Volume VA is centered on the peak volume price, called the 'point of control'. This is the original end-of-day VA. Within the day, Market Profiles develop. These use TPO's to identify market activity, so-called TPO volume. A natural extension led to the TPO VA. A study published in the Market Logic School Alumni Letter (Vol 1, #3, April 1987) compared the two VA methods, showing a close correlation.

At the close of March 22, the T-bonds LDB report give the volume value area as 10704 - 10624, while the TPO VA is 10705 - 10625. They are essentially the same. There is no special demand that skews the distribution. Thus, the VA gives us no additional clues to help interpret this day. The general VA information situation is illustrated in the following.

Recent studies for the special case of the S&P Index show some substantial deviations from correlation. There will always be some deviations between any two methodologies. The peak volume may not correlate with the peak TPO, so the point of control will differ. Volume normally is thought of as directly showing demand. Trading strategies intended to mislead can artificially create large volume at particular prices. This is not true "demand volume", but even an LDB report has no way of telling. On a temporal basis, the artificial volume is fed into the market in a short time to maximize the shock effect. But a short time of activity does not create a lot of TPO's. So the Market Profile VA tends to ignore such strategies. The conclusion is that one best have both VA's. When they disagree, one can go back to the LDB report to determine which best describes the value.

As an example, not a complete study, the difference between the volume value area from the LDB and the TPO value area from tick data for February 2002 S&P's are:

   01/31           8.9                3.5

Table SC-T2.  Value area differences.  TPO value area is subtracted
from volume value area.  1.0 is $250.  

For the upper value area price the average deviation is +1.1. The lower value area price shows an average deviation of -0.6. On the average, the deviation between the two measures is not unreasonable.

But the average is not relevant in the large deviation cases such as February 8. If two measures of the same thing, value, differ wildly something must be wrong with one of them at least. It is a wake-up call for the trader. These data are available in the evening prior to the next day's market. There is time to study the raw LDB data, the source of the value areas. There is time to come to a conclusion on the one to use.

The LDB report for February 8 is in figure SC 13. At the close of February 8, 2002, the S&P Index showed a Volume VA of 109850 - 1108450, with a point of control at 109600 at a volume of 5686. TPO VA is 108770 - 108000. The upper VA is 10.8 points ($2700) apart.

Figure SC 13.  Liquidity Data Bank report for March 2002 S&P futures
on February 8, 2002.  Volume value area is labeled Vol VAU and Vol VAL.
TPO value area is TPO VAU and TPO VAL.
A look at the actual LDB report shows one peak of activity, centered around 108380, the TPO point of control (POC is the maximum TPO count). The volume POC, at the high volume point, is at 109600. What is the source of the excess volume in an otherwise normally trading market? It is easy to see:

    CTI1 Floor Members average percent volume is 53.2. At 109600 it is 43.8.
    CTI2 Commercials average percent volume is 2.3. At 109600 it is 3.0.
    CTI3 Off floor members avg percent volume is 7.1. At 109600 it is 0.6.
    CTI4 Public trading average percent volume is 37.4. At 109600 it is 52.6.

So it is the public that was big at 109600. All this activity came within the closing half-hour period. The public, who hold overnight, are the source of demand. It is possible that the demand picture changed late in the day of February 8 and that change is mirrored in the volume value area. In such a scenario, the TPO value area represents trading that has since been superceded by changing demand. One would go to the overnight market to see if the volume value area is sustained.

Examination of night trading shows the high 109's were sustained throughout the night, with the rise continuing into the next trading day, which closed at 111020.


The T-bond with the largest deviation in Table SC-T2 is February 4. The LDB report is in figure SC 14

Figure SC 14.  Liquidity Data Bank report for March 2002 T-bond futures
on February 4, 2002.  Volume value area is labelled Vol VAU and Vol VAL.
TPO value area is TPO VAU and TPO VAL.
The TPO value area is about 5 points (about $160) above the volume value area. An examination of trading at the volume point of control (peak volume) shows it came early in the day. TPO's Z$ABCD go from opening at 7:20 AM (Z period) through D period (9:30 to 10 AM). Point of control for the TPO's is 10331. TPO's at that price are DEFJKL (9:30 AM through the close at 2:10 PM). Value did move up during the day. The TPO value area reflects the later value. While 5 or 6 ticks is not a lot, it still represents over $150 in locating the day's value. The trader who knows which value area most represents the market has the edge.



Conclusion

Auction Market Theory shows the structure and patterns of auction markets. It provides the tools to convert price to value and value change (Market Profile) and to market condition and risk (Overlay Demand Curve). The theory allows you to deconstruct a market from it's current condition. To look inside, so to speak. In addition to value, condition and risk, you can know which prices are accepted, which rejected. You can often even know what the members are doing. Yes, you can understand your market. You have the salient facts and these facts lead to conclusions. We call these conclusions 'strategy'. Understanding your markets imbues you with a confidence unfamiliar to most traders. When you know, and know that you know, confidence replaces fear.

An advantage of understanding the market and setting up a strategy based on that understanding is that if your strategy turns out to be wrong you know it very quickly. The swing trader will know when a breakout fails. A swing trader will also have a strong clue when a trend falls into congestion--in hours, not days. Day traders, too, will usually know when market conditions change, say from balance to trend, and so can react accordingly.

The generality of the theory makes it a starting point for much new market research. One area, just being explored, is the measurement of reward to risk ratios. An early finding is that the Dow Jones Index has a reward to risk ratio about twice that of the SP Index. Another area is categorizing markets by trading opportunity. Now that the initial development is in place, and with a theory to lean on, there is a vast arena of practical market applications waiting to be discovered.


Unfinished Business

But wait. A lot of analysis went into developing a strategy for trading on March 23. How did it work out? Our trading strategy TS1 - TS14 indicated a small liklihood of any further upward activity. No new demand entered. The market of March 23 confirmed our analysis. It is a classical 'dead' market. The events of March 22 took the wind out of the trader's sails. The day market opened at 10610 and stayed within 10 ticks of that price all day long.

The market congested all day.

Recalling some of our analyses:
TS4) Early congestion followed by massive later congestion on 3/22 is indicative of a market confused about underlying demand
TS5) A breakout tomorrow is unlikely because of the congestion picture in the last few hours of 3/22.
TS6) This is a low priority market for the breakout swing trader
TS11) Unless new upside demand enters the market, the odds are that the Overlay tomorrow will pull back, i.e. 10708 is a local high.
TS12) Understanding the probable cause of the rise on March 22 does not substantially change our strategy for March 23. Corroboration adds confidence in the original analysis.

The Market Profile of March 23, in figure SC 12, fits neatly into the Overlay of March 21. The breakout on March 22 is shown to be a transient, not due to any pemanent change in demand or value. The trader can totally discard the action of March 22. Trading action of March 22 did not alter the value picture of the market. Trading analysis for Monday, March 26 can be based on figure SC 8, the Overlay of March 21!





Disclaimer

Reports such as this one rely on examples to illustrate their principles. Sometimes the case selected has unusual properties, ones that the reader would rarely meet in trading. That is not done here. Our intent is to show how to understand the markets you work with and from that understanding to permit you to develop your own trading strategy. Our example would have shown a loss or possibly a wash if you are a swing trader, and likely a winner if you day trade. The example is intended show a complex market situation and how you can use the theory to make sense of it.

This example was chosen entirely on the basis of a balanced market (March 21) breaking out the next day. No other criteria were applied. It was not known initially that the breakout fit the short-covering-rally picture, nor did we know that the buy/sell data or the commercial trading would support the short covering hypothesis. It is a fortuitous benefit of the analysis that a short covering rally, confirmed by the buy/sell data and commercial capping were found. Had there been no confirmations, the original analysis would have been rechecked with a critical eye. It is a fact that Auction market analyses often uncover surprising and unexpected market features. These always add to market understanding.

Daytrading Support and Resistance


Donald L. Jones
CISCO Futures
July 20, 2002

Day trading the market indexes is a fast growing arena. Market Profile value analysis for short term support and resistance (i.e. the value area) is currently in vogue. Unfortunately, few traders realize that Market Profile values are not at all reliable under certain circumstances. Such situations occur about one-third of the time. In this article we show how to identify and resolve the unreliable situations.

Recently I wrote on Auction Market Theory, the framework within which auction markets operate (ref1, ref2). Three auction market structures are covered: Market Profile, Liquidity Data Bank (LDB) and Overlay Demand Curves. In this work I will draw from the Market Profile (which is being used by many traders) and the LDB (which is not). To briefly review, Market Profile builds a utilization picture of market activity by marking the times at which trading took place. LDB posts volume at price, regardless of time of occurrence. LDB displays typically include a Market Profile.

Market Profile, a Summing Process
In the earlier articles Market Profile was shown to be a tool for finding the market's perceived value at the end of the most recent trading day. A profile is a graphic that sums the frequency of trading at each price with TPOs (trading at a price in a particular timeframe). Profiles post and integrate the trading over the entire day. The net result is a bell shaped price-time chart where the central 70 percent of the action defines value. Price at the peak of the summed activity is called the point of control, or POC. POC of the Market Profile will be identified as "TPO POC". The Market Profile in figure 3 has a TPO POC of 101400 with value area limits 101850 - 101050. A summing process for determining value works well for markets in balance but can be quite wrong if value changes within the day.

Liquidity Data Bank, a Point Process
An alternative method of value measurement, independent of the profile, uses the volume figures from the Liquidity Data Bank (LDB). LDB's in ref2 located the prices at which commercial traders dominated the market. The same volume data can be used to find value. The peak volume price for the LDB is also called the center of value or POC. Unlike the profile, in which the POC is the sum of a number of events, POC on the LDB display can be created by heavy trading in a very short time. The weakness of a point process is that a maximum trading price may be superceded by a region of not-quite-as-much-volume at a group of prices. The new region could dominate in terms of value, but the price from the one big volume point would remain the point of control.

Points of Agreement/Disagreement
In stable markets both profiles and LDBs find essentially the same value centers and value areas. Should demand shift within the day, one or the other will likely be wrong. Below, we examine a shifted value day in which the difference between the profile TPO POC and LDB volume POC are large. The big difference between the two is the tip-off that value has moved. The trader following the correct value figures (LDB, in this case) will have numerous trading opportunities the next day. The profile values offer none.

Value Calculations
There are two value determinations from the S&P of June 11, 2002, the profile and the LDB. Each will provide it's own self_consistent support/resistance, or value areas. Value limits found will be used in trading the market of June 12. We can get both value areas from the Liquidity Data Bank display, which posts price, volume, volume distributed among the four classes of floor members and the Market Profile. We are concerned here with only the price, volume and profile columns (a full discussion of the LDB is on the website of ref3). S&Ps are highly volatile, with wide daily trading ranges. Figure 1 is a shortened LDB report for June 11, to illustrate the format.

Figure 1.  Partial listing of a standard LDB for S&P June 2002, 
June 11 2002.  Volumes are reported in sides, where two sides
make a round turn, or complete trade.  Trading is concentrated 
at the 00 and 05 price levels.  Example:  103600 shows 3214 
sides traded; 103520 shows 1520 sides traded and much less 
trading at the 'odd' prices 103590, 103580, 103570 and 103560. 
The dominance of trading at 00 and 05 is consistent for the S&P.


The S&P is characterized by heavy trading at the 'even' prices 00 and 50, with much less at the 'odd' prices 01, 02, 03, 04, 06, 07, 08 and 09 (odd and even refer to market acceptance, not mathematics). Indeed, even in a relatively heavily traded market some 'odds' are not traded at all (e.g. no trading at 104010, 103990, 103910, etc.).

In a search for the peak volume price, the 'odds' play no role at all and may be ignored.

Figure 2 is the full LDB for June 11, with the 'odds' removed.

Figure 2.  Volume at major 'even' prices.  Columns: 1 is price,
2 is volume (1/2 of round turn) and column 8 is a Market Profile.
Columns 3, 4, 5, 6, and 7 show trading statistics for the four
classes of members on the floor and are not used in this article.
Value areas from the Market Profile (TPO) and from the volume (vol)
are identified by the arrows on the right of the display.

In figure 2, column 2, the peak volume of 4212 occurs at a price of 101400. 101400 is then the center of value (POC) for volume. For the Market Profile on the far right, the peak TPO count (POC) of 6 is at 103500 (or 103550). The centers are far apart. Both cannot describe value at the end of the day. Which is correct?

Auction Market Analysis: Reading the Market
Market Profile is clustered around trading activity in periods B through G (8:30 to 11 AM, each letter identifies a 1/2 hour trading period). The 70% value area is from 104020 to 102510, marked as TPOVaU and TPOVaL on figure 2. The volume value area, centered at 101400 (periods N and O (2:30 to 3:15 PM)), is 103500 to 101210, identified as volVaU and volVaL.

Market Profile says value (demand) is at the top of the trading range, which it is from the open to 11 AM. Volume places maximum demand later in the day, near the bottom of the price range. From the profile part of figure 2, it is clear that the market opened (B period) near the highs and did quite a lot of trading there. Demand began shifting downward around H period (11:30 - 12:00) and moved steadily down the rest of the day. Market Profile value was superceded by the appearance of heavy volume late in the day. In this example the volume value area is the correct descriptor of end of day value.

To recap:
1. Demand centered around the price 103480 until about 11 AM.
2. Then price started down, pausing at the 102700 level (11:30 to 14:00).
3. The next run ended at the 101400 level near the end of the trading day.
Both the profile and LDB are correct for their respective times of day. But the trader needs to know which value area to use for tomorrow and that is clearly
