Background on Exchange Total Contract Volume Averages Table

These table gives the minimum (Min), average (Avg), maximum (Max) values of
the Exchange contract volumes for the last 90, 5, 10, 15, 20, 40, and 60 
trading days. 

For the last 90 trading days the tables ALSO give the 68% deviation (Dev)
of the values about the average i.e. 68% of all the Exchange contract volume  
values in the last 90 days are contained in the range: average-68%deviation 
to average+68%deviation. 

The tables are updated daily around 10pm. The leading deliveries are
used for those commodities that are not asterisked. For the asterisked
commodities the nearest delivery is used and for them there is often
insufficient data to calculate the 90 day deviation.

The tables are up-to-date on the day of trading.

Since the Exchange contract volumes ONLY become available at 10 am the
morning following trading, the tables are a day behind as far as being
up-to-date.

High Volume is values greater than 90 day average+68% deviation
Low  Volume is values lower than 90 day average-68% deviation
Normal Volume is values between average-68%deviation and average+68%deviation
