Background on Daily Price Range Averages Table

There is the daily price range table and the daily price range in dollars
table.

These tables give the minimum (Min), average (Avg), maximum (Max) values of
the daily price range 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 daily price range  
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.

High daily range values are greater than the 90 day average+68% deviation
Low daily range values are lower than the 90 day average-68% deviation
Normal daily range values are between average-68%deviation and average+68%deviation

The use of this information in a trading strategy is covered elsewhere.
