VolumetricBars Delta chng

[franki]

Hello, from the page ------> https://ninjatrader.com/support/help...flow_vwap2.htm

I have taken the references, but in the chart there is a parameter that I need, but it does not come in the reference page.
How can I get this value?
I think it's BarDelta [1] - BarDelta [0]
I did the test of
Print ("Delta Chng" + (barsType.Volumes [CurrentBars [1]]. BarDelta - barsType.Volumes [CurrentBars [0]]. BarDelta));

I would appreciate a correction and if possible more extensive documentation of the reference page.
Thank you so much!

Hello franki,

Thank you for the post.

Your code snippet is correct for getting the delta change value. I believe that was not documented because it is not an "atomic" property of volumetric bars. I will submit a request to add a note to the help guide page regarding this.

Thanks in advance for your patience.

Hello, if the code is ok, it has no representation in ninjascript output, in my first message I attached an image ....
At the start of OnBarUpdate I called "CurrentBars" under
if (CurentBars [0] <1)
return;
if (CurrentBars [1] <1)
return;

I've searched for more information at https://ninjatrader.com/support/help...urrentbars.htm
and in more references to CurrentBars
But one makes a call to an indicator and the other references configure multi-timeframe.
I do not find correlation with my need.
Please, do you have a practical example for CurrentBars in the circustance that I am looking for?
I am very grateful for your attention.
Thank you.!

Hello franki,

Thanks for the reply.

You can calculate the delta change like so:

Print("Delta for bar: " + (barsType.Volumes[CurrentBar - 1].BarDelta - barsType.Volumes[CurrentBar].BarDelta));

I have also attached the full test script.

Please let me know if I can assist further.

Hello again!
Thank you very much, the command of the message was enough, so I thank you for the help you have taken to make the script.
Nothing else I had to change the negative sign of position because it differed in the chart and appeared inverse values.
From what I see if I want data from candles afterwards to CurrentBar, I just have to adjust like "[CurrentBar - (nºbars ago)]"
I'm really grateful to you.
