Since you haven't learned MQL4/5, therefor there is no common language for us to communicate.
If we tell you what you need, you can't code it.
If we give you the code, you don't know how to integrate it into yours.
We are willing to HELP you when you post your attempt (using Code button) and state the nature of your problem, but we are not going to debug your hundreds of lines of code. You are essentially going to be on your own. -
EA builder makes bad code counting up while closing multiple orders.
EA builder makes bad code Bars is unreliable (Max bars in chart), volume is unreliable (miss ticks.) Always use time.
EA builder makes bad code, not adjusting for 4/5 digit brokers, TP/SL and slippage.
EA builder makes bad code, not adjusting for ECN brokers. pre-Build 500)
EA builder makes bad code, not checking return codes. -
EATree uses objects on chart to save values — not persistent storage (files or GV+Flush.) No recovery (crash/power failure.)
