Good evening! Thanks for accepting me in the forum.
In a old conversation about Waddah Attar Explosion, I found a Multi Time frame version which I would like to use for testing some EAs. However When I run this indicator in backtesting, it freezes and it does not update higher time frames, photo below. I don't know if it freezes also in real time but I'm not able to understand the problem and if this is a problem that I can resolve in some manner.

I also attach the indicator which I found, coded by mladen.

Thanks for your help in advance!
