need help whit an indicator

[Nigry]

If you want to try my transformation into that indicator's strategy. Unfortunately, the openings of the operations take place at the closing of the previous candles (obviously) and this is the difference between automatic strategies and indicators. Of course, I do not know if my code is correct, I'm just an amateur, maybe the experts of this forum will be able to improve my work ...

However, for me, the outcome is not bad on high timeframe (Daily / 4 hours), even if I did not have time to find optimized parameters ...

Code:
