Close all pending when first order go Stop Loss

[Luca De Andrea]

Hi guys, I'm new on this forum.

I have an EA that under certain conditions opens multiple buy or sell orders, the first to market, the others are pending. I want that if the first market order goes to stop loss, all other pending orders are automatically closed. Can someone help me? I guess it must use the magic number

i use MT4, I don't know if it's correct to post the topic here

Sorry for my bad english

1. You posted your MT4 question in MQL4 section, (bottom of the Root page?) or it has already been moved there.

2. Once one order opens, monitor your open orders count. If there aren't any then delete all pending.

3. Magic number just allows you to identify the EA's orders from all others. Using OrdersTotal/OrdersHistoryTotal (MT4) or PositionsTotal (MT5), directly and/or no Magic number filtering on your OrderSelect/Position select loop means your code is incompatible with every EA (including itself on other charts and manual trading.)
