Attempting to add volume bars together for a given period

[loujen213]

I am all over the place trying to figure this out. Two places I am having trouble. I want to add the volume of each bar together for a set period. That is what I thought I was doing below.

{
double volSum = 0;
for (int i = 0; i < period; i++)
{volSum+= Volume[i];}
Value.Set(volSum);
}

I also want period 1 to start at the open of the RTH.

I have set my period to 435 for the number of period bars on the 1 minute chart. I am trying to run a cumulative total for volume for the RTH 9:30 to 4:15

loujen213, you would also need to reset the count at the session break, so each RTH part is counted.

Sorry my programming understanding is very limited. How would I code that in my above line. Thank you

There are several ways to do this, one would be for example -

Value.Set(SUM(VOL(), Bars.BarsSinceSession)[0]);
