Values from volumetric bars don't match

[PedroNunes]

"Hello, I have a script that prints the MaxPositiveDelta and MaxNegativeDelta for the last closed volumetric candle, but the values don't match those shown in the bar statistics grid.
Can you help me?"

VolumetricBarsType barsType = Bars.BarsSeries.BarsType as VolumetricBarsType;

if (barsType == null)
return;

Print("Bar: " + (CurrentBar - 1));
Print("Maximum Positive Delta: " + barsType.Volumes[CurrentBar - 1].GetMaximumPositiveDelta());
Print("Maximum Negative Delta: " + barsType.Volumes[CurrentBar - 1].GetMaximumNegativeDelta());

Hello PedroNunes,

The last closed candle would be only CurrentBar, you are currently using CurrentBar - 1 which would be the bar before the last closed bar. I can see on my end the values are matching the chart for the 3rd bar from the right which would be 1 bar before the last closed bar.

Thank you for your fast response. I am using volumetric volume bars and the values still don't match.

Hello PedroNunes,

The value you are printing should not match the most recent closed bar, you are printing the 1 bars ago value. Do you also have delta mode enabled by changing the chart style to delta? By default the bars don't show the delta.

[PedroNunes]

I am sorry, my mistake. What I want to include in my strategy is the max. delta and min. delta for the entire closed bar (the ones from bar statistics). Is it possible to print that?

Hello PedroNunes,

That is what you are printing in the code you provided but you are printing the 1 bars ago value. To print the current bars value you would need to use CurrentBar in that syntax and not CurrentBar - 1. The - 1 is subtracting 1 from the CurrentBar variable giving you 1 BarsAgo data.

As long as you have the chart style set to Delta you should be able to see that print match the chart bars.

Print("Maximum Positive Delta: " + barsType.Volumes[CurrentBar].GetMaximumPositiveDelta());
Print("Maximum Negative Delta: " + barsType.Volumes[CurrentBar].GetMaximumNegativeDelta());

Hello, here is a screenshot of what I want in my strategy.
Thank you

Ok, I think this is it:
Print("Max seen delta (bar): "+barsType.Volumes[CurrentBar].MaxSeenDelta);
Print("Min seen delta (bar): "+barsType.Volumes[CurrentBar].MinSeenDelta);
