Pivot Points, a Critique
By Donald L. Jones©
August 14, 2005

There is no 'trading university'. A potential trader typically looks for training and educational courses on the internet or through a brokerage firm. Most of these sources have a goal, brokerages to get the new person trading as soon as possible; purveyors of courses to get the newbie to take their course. Neither route seems to be very successful, since it is reported that some 90 to 95 percent of new traders fail within their first year.

The courses often teach a goodly amount of worthwhile information; a respect for leverage, a reasonable approach to risk management and so forth. Most courses fail where the rubber meets the road, at the trading model level. Most analysis schemes rely on some sort of smoothing, e.g. moving averages and oscillators. Some use an elegant display method called 'Japanese Candlesticks'. Possibly the most egregious model of all is 'Pivot Points'. If the vast majority of new traders lose, it is fair to concede that none of the methods promoted by trainers work. The fault of pivot points is their innate simplicity and their story, that pivot points are used by members on the floor.

Pivot Points Defined
We use a day timeperiod for illustration, but any other consistent timeframe will suffice.
At the end of a day we have the Open, High, Low and Close: O, H, L, C.

Let P = (H + L + C)/3. This is a sort of center of gravity for the day.
The second resistance: R2 = P + H - L. This is the 'far' resistance.
The first resistance: R1 = 2P - L. This is the 'near' resistance.
The center is P.
The first support: S1 = 2P - H. This is the 'near' support.
The second support: S2 = P - H + L. This is the 'far' support.
For example, take the case where H = 110, L = 90 and C = 91:


  P = (110 + 90 + 91)/3  =  97
    R2 = 97 + 110 - 90   = 117
    R1 = 194 - 90        = 104
    S1 = 194 - 110       =  84
    S2 = 97 - 110 + 90   =  77
The formula computes, but what does it mean? Roughly it says that if tomorrow trades exactly like today then 104 is an upside breakout point and 117 is a confirmation of the breakout. The same is true on the downside at 84 and 77. Think for a moment; if tomorrow's market is the same as todays, a price of 104 is not a breakout, because the high will be 110. For the downside, however, a price of 84 is a breakout and really would be a breakout compared to today's prices (the actual point is 90, price below that is a breakout). The formula does not give symmetrical results, but you would expect it to do so. It turns out that the close, in this case, pulls the calculation down. But in a balanced market, the only place where a support and resistance pair can be correctly found, the close rotates within the balance and hence is of minimal importance. You can read about the Meta-Profile which discusses the relative importance of highs, lows and closes in an ongoing market.
Market/Meta Profiles Background

Further, it has been known for many years that markets are not day-to-day serially correlated (ref 1). So, to bet your money on a single sample is pretty risky.

Well, where comes this story that floor members use pivots? It turns out to be true. New floor members are strongly encouraged to minimize their trading risk. Just like the public, they have a tendency to stay with a bad trade too long. Hence the use of pivots. If their position goes against them by a first (near) pivot point, get out. If they are still holding when the position deteriorates to the second (far) pivot point, they know they have been a fool. So they generally use the pivot ranges as an alert that they have stayed too long with a bad trade. But not to get in on or out on the pivot supports/resistances.

In the real world of trading, successful traders know that one day alone rarely guides one's trading. What happens today is important in the context of the market's overall behavior. Is the market in balance? If so, then today is just another undistinguished day in the chain of days in balance. If the market is directional, today is important for showing signs of latent congestion. If congestion appears, then one exits one's directional trade. If there is no congestion showing, then one stays with the trade. A simple calculation of a pivot point offers no information on the congestion question. Remember, it is the trader's job to get aboard a directional move and to exit when congestion sets in.

There is a valid way to find near term support and resistance from one day's trading. The market must be in balance for the Meta-Profile to measure support and resistance from the entire day's trading behavior, examined for multiple periods through the day.
Market/Meta Profiles Background

CISCO teaches market analysis and trader training. Nothing in the CISCO courses suggests that pivot points or any of the other standard 'indicator' methodologies can help a trader to success. Trading is a sophisticated profession and like other professions, there is a learning curve. One formula like the pivot points, even if they gave valid evidence, would simply be a step in the learning process.
