Need some help refining an EA

Hey there

I have been spending a bit of time trying to develop an EA with an online template and have created a successful one.I want to take it to the next level by refining details.I want to be able to open 3 orders at once with different tp targets aswell as a trailing sl for 3rd position to capture the larger moves.

If anyone can assist would be much appreciated.Current backtest is at 400% over a 12 month period and with only a 3% winning ratio.

Cheers in advance
