Make indicator code lighter to run faster

Hi, I need to fix the code of an indicator that is heavy and slows down backtests when integrated into an EA through iCustom or into a multi-symbol dashboard. The problem is neither with the EAs nor with the dashboards because with other indicators they work quickly (even non-native indicators), so it is really a question of bugs in some loop or other type of bug.

I request the final file as source code in mq5.

Thank you
