The problem is obviously not in the loop.
Any ideas what the problem is? Algorithm within the loop can't be the reason.

I think there is a problem with the implementation of the old IndicatorCounted() function
There are so many errors it is amazing that something is displayed.
Have you read documentation on indicator with MQL5 ?
I draw your special attention to timeseries access.
P.S: Moreover, there are also small errors in the version MQL4.
I haven't check the entire code, but you should change
into DRAW_HISTOGRAM.
Thank you phi.nuts for your info, but I think there is more than this. Same result.
I think I have to study all the stuff that angevoyageur recommended. One day I will find the error even more...
Thank's for your suggestions.

You are welcome. Keep us informed of your progress.
I post you what I have tried with your code, but I don't have more time to continue. May be that help you.

Hy,
I want to have an indicator which was originally coded in MQL4 in MQL5. Everyting is ok so far. Just one warning with data conversion. But that is ok.
My question is about the indicator loop in function OnCalculate(). I'am not sure with the new code for the old indicator loop:
Old version
My new version for MQL5:
The result in MT4
And the result for my MT5-Code :-(
I'am looking for some help with the indicator loop above.
Thanks
