Getting Volumetric data for previous bars

[Ousher]

This code below grabs the max/min delta of the current bar along with the prices.

double maxprice;
double minprice;
double maxdelta = maxprice = double.MinValue;
double mindelta = minprice = double.MaxValue;
for (double p = High[0]; p >= Low[0]; p -= TickSize)
{
if (barsType.Volumes[CurrentBar].GetDeltaForPrice(p) > maxdelta)
{
maxdelta = barsType.Volumes[CurrentBar].GetDeltaForPrice(p);
maxprice = p;
}

if (barsType.Volumes[CurrentBar].GetDeltaForPrice(p) < mindelta)
{
mindelta = barsType.Volumes[CurrentBar].GetDeltaForPrice(p);
minprice = p;
}
}

What I'm trying to get is the previous bar data as well. I changed

[CurrentBar]

to

[CurrentBar-1]

but that didnt work.
Any help?

Thanks!

Hello Ousher,

The volumetric data uses the CurrentBar for the index instead of a BarsAgo, if you wanted previous data you need to use CurrentBar - 1 for the previous bar.

Are you sure the values for the given prices were different?

I can see different values printing the CurrentBar and CurrentBar -1 for the other Volumetric values.
