I want to know if the volume is greater than the volume within the past 30 bars.
This is what I am working with so far..obviously not working...

if (CountIf(delegate {return Volume[0] > Volume[0];}, 30) > Volume[30])
{

}

try to use a list that adds the volumevalues every bar. you then can always look back the last 30 entries and compare whatever want to compare, which i didnt even understand. the sum of the last 30 candles, the average or the maximum or what?

look at this post for a sample of a code that has a very similar mechanic.

EDIT2:
make sure to use
using System.Collections.Generic;
using System.Linq;

1. The part marked in blue is obviously never true, so ...
2. What does the request mean? This statement is impossible to understand: "... the volume is greater than the volume within the past 30 bars. "

Hello brucelevy,

Thank you for your inquiry.

Can you please clarify what you mean by "the volume is greater than the volume within the past 30 bars"?

If you're trying to find the highest volume over the last 30 bars, you can utilize the MAX indicator: https://ninjatrader.com/support/help...aximum_max.htm

For example:

// prints the highest volume value over the last 30 bars
double value = MAX(Volume, 30)[0];
Print("The highest volume over the last 30 bars is " + value.ToString());

Yes, thank you it seems I may have been very unclear. I was however able to utilize the MAX method by searching for the max volume, then checking if the current volume was higher.

Thanks again.
