Orders for Expert Advisors development - Forex - new

I want to develop a fully automated trading robot from scratch. The project includes 8 different pdf - one for Settings of the EA & Trade Management. Other 7 are different St (trading strategies/logics). All Settings & St are to be housed in a single MQL5 EA. The EA is to be attached to a single chart, but it must work on every chart of 65 symbols at a time without any failing or compromise with performance/speed. I

Need a simple one indicator EA to duplicate what I've been doing manually. It should have the usual inputs; Break-even, SL, TP, lot size et al Based on pending orders and drawing lines with these orders. Thanks
