MQL4 - How to close 2 orders without delay?

Hello,

I need to close orders in pairs within a very short time. Any delay could mean a loss. If both can't be closed right now, better close none.
How do you code a bulletproof way to do this with MT4 ?

One order may be closed while suddenly the connection breaks down, we get TradeContextBusy and all this crap .. is there any way to work around this and close two orders 100% or not at all ?

It seems the only way is to set a StopLoss as orders will be closed server side, but what if only one order gets the SL set and while I try to set the 2nd SL problems happen ?

My EA can be found here:

100% - good luck finding a solution.

Server side is your best option, as this takes away the communications risk.

In any case, there's no way for an EA to close 2 orders at a time. MT4 platform is allowed to send 1 request only at a time. Each order is then subject to the broker's delay (liquidity/slippage/requote...).

Yes your best option is to set a TP or SL when you see your exit point is coming.

You need to use 2 EAs or 2 Scripts, MT4 can now support upto 8 trading threads so if you have more than one EA you should no longer get "trade context busy" due to the conflict between EAs.
20 pips a day isn't too much to ask . . .

Yes but in this case, the 2 orders to be closed by 2 differents scripts must have a different ID. If not, both scripts will try to close both orders. It might work but in some cases there will be conflict.

Thats simple to take care of, for the case where there are 2 orders to be closed one script/EA is configured to close the higher ticket number the other to close the lower ticket number. There are probably other ways of doing this without conflict.
