What happens when stop loss operates

[Sneck55]

Hello, how should I make my EA aware that a stop loss has occurred please? At the moment, when this happens, a lot of errors occur because the program doesn't know the position has been closed automatically. Thank you.

when orders hit stoploss, then orders closed with comment: [sl]

Yes I realise that but how do I make the EA aware of the order being closed by the stop loss?

it's a good question buddy by the way you talk about mql4 or mql5?

There's a  number of different ways you can do it and it's really going to depend on the logic of your code and also if it's mql4 or 5. Some quick suggestions:

• Don't set a hard stop (order SL). Control the stop in your code
• Hold open order tickets in a variable (struct, array etc) then check to see if they're still open
• Select and analyze closed orders from the pool using MODE_HISTORY
• And more....

Hope that gets you started

Cheers
