Jaouahr Younes: Hello, please can somebody help me with this code?
Traders and coders are working for free:
if it is interesting for them personally, or
if it is interesting for many members on this forum.
Freelance section of the forum should be used in most of the cases.
NOTE: some details in your code are common for AI-generated, so it can be hardly helped (would need considerable human review/corrections before being usable in a live trading environment).

Why did you post your coding question in the MT5 General section (a miscellaneous catch-all category) instead of the MT5 EA section (non-indicator coding)?
General rules and best pratices of the Forum. - General - MQL5 programming forum? (2017)
Next time, post in the correct place. I have moved this thread.
