Counting elapsed bars issue

[MisterGee]

In my strategy I have something similar to (forgive any syntax errors, this is just for general premise)

if (Open[0] > Close[1])
{
EnterLong();
EntryBar = CurrentBar;
}

if (MarketPosition == Long)
{
BarsElapsed = CurrentBar - EntryBar;
Print(BarsElapsed);
}

I have this printing to the output window and when a position is held the output will read sequentially 1, 2. 3. 4 etc.. but randomly it will be something like 1, 2, 3. 4, -2238, 5, 6, 7

I have been running these lines of code for some time now and it has just recently started happening. I am running on replay connection for ES 12-20 and ES 03-21. Strategy is OnBarUpdate

Hello MisterGee,

Is AddDataSeries used in the script in State.Configure?

[MisterGee]

It is, but is not called in the rest of the coding.

Hello MisterGee,

OnBarUpdate will run for every series added to the script.

Likely you are seeing updates from the other series. Add a condition to return if BarsInProgress is not 0.
