Background on Bracket Range in $ Averages Table

These tables give the minimum (Min), average (Avg), maximum (Max) values of
the bracket range in $ for the last 250 trading days, for 5, 10, 15 and 20
day overlays.

For the last 250 trading days the tables ALSO give the 68% deviation (Dev)
of the values about the average for 5, 10 ,15, and 20 day overlays.
i.e. 68% of all the bracket range in $ values in the last 90 days are 
contained in the range: average-68%deviation to average+68%deviation. 

For the appropriate overlay (i.e. 5, 10, 15, 20 day):
High Bracket Range in $ are values greater than 250 day average+68% deviation
Low Bracket Range in $ are values lower than 250 day average-68% deviation
Normal Bracket Range in $ are values between 250 day average-68%deviation and average+68%deviation

Also in the table under the heading "B/T" is ratio of bracketing days to 
non-bracketing days, for 5, 10, 15, 20 day overlays.

Also in the table under the heading "Brackets" are the minimum (Mi), 
average (Av), maximum (Mx) and 68%deviation (Dv) values for the
number of days in an un-interrupted group of bracketing days, for the
last 250 trading days, for 5, 10, 15, 20 day overlays i.e. a measure
of how many days a bracket stays in bracket.

Also in the table under the heading "Non-Brackets" are the minimum (Mi), 
average (Av), maximum (Mx) and 68%deviation (Dv) values for the
number of days in an un-interrupted group of non-bracketing days, for the
last 250 trading days, for 5, 10, 15, 20 day overlays i.e. a measure
of how many days a non-bracket stays a non-bracket i.e how long an
overlay takes to get back into being a bracket.

Also in the table under the heading "Brackets" is the number (No) of
un-interrupted groups of bracketing days, for the last 250 trading days, 
for 5, 10, 15, 20 day overlays. This is similar to the "B/T" ratio
but multiple counting is removed.

The tables are updated daily around 10pm. The leading deliveries are
used for commodities. They are up-to-date for the latest day of trading.
