7413276 2021.01.04 17:16

Hello everyone, I would need your help with my EA. I would like to send when the purchase conditions are met, at the same time a "buy" order and a "buystop" order, and when the sale conditions are met , I would like to send a "sell" order and a "sellstop" order ... it's been a while since I tried several methods to get there without success ..... thank you in advance.

"Hedging" in Forex trading -Why do it? - Trading Systems - MQL5 programming forum 2017.01.18

Good evening William Roeder

This is not a "hedging" because the orders are not in opposition but carried out in the same direction when a signal is presented ... either: 1 buy + 1 buy stop, .... or: 1 sell + 1sellstop ... it's one or the other but not both at the same time ... the goal is to strengthen a position that goes in the right direction ... thank you for your intervention.
