Is there a way to get the number of bars between two times on a chart?

[ErikY]

I am trying to do an interpolation calculation for an indicator. I cannot use the actual dates of the interpolation because it does not account for market closed time.

Wondering if there is a way to do this off of bar count. So for example, if I want to calculate the rate of change between say 1/1/2021 and 1/10/2021, I want to do something like this, Rate = (Price 1 - Price 0 ) / (count of Bars between 1/1/2021 and 1/10/2021)

If I do this with date diff to seconds, my interpolation is scrwed up because of the closed market. Only way I can think to do this is with bar counts, but open to other ideas if anyone has

Hello ErikY,

It is possible to get the number of bars between two bars selected with Bars.GetBar().

https://ninjatrader.com/support/helpGuides/nt8/getbar.htm

DateTime startDateTime = new DateTime(2021, 10, 24, 0, 0, 0);
DateTime endDateTime = new Date(2021, 10, 24, 15, 0, 0);

int numBarsBetweenBars = Bars.GetBar(endDateTime) - Bars.GetBar(startDateTime);
