How to show sum of Openint on weekly chart?


I find that the openint value is same as the daily and weekly chart. Any option can change its behaviour.

OpenInt in compressed bars is compressed as "close", i.e. it is last value from given period. So it is number of open interest at the end of the period.

How I show openint as volume because my openint column store money value.

Use Aux1 and Aux2 fields for custom data. They allow user-definable time compression methods (in File->Database settings->Intraday settings)
