Maximum trade triggers of an EA

Hi,

I attached an EA on 20 different pairs 1 Hour charts, the EA suppose to trigger trades on ALL pairs simultaneously that met the criteria.
But I noticed there were instances where 15 pairs met the criteria but only 3 pairs triggered the trades, another instance where 12 pairs met the criteria, only 2 pairs triggered the trades.

Is there any limitations on trade triggers by an EA ?

Appreciate anyone could shed some light or share your experience please.

TIA.

It might help if you said what platform you are using ? Ninja, MT4, MT5 ?
20 pips a day isn't too much to ask . . .

Hi RaptorUK,

It is on MT4 build 509.

And there is no error in the log/journal, that's why it beats me what could have failed.

The person who coded the EA would know the explanation. Without knowing the details of how it works, it is very hard for someone else to figure out.

Hi CodeMeister,

The EA is working fine, code wise. I'm wondering is there any MQL4 internal program code restrict that ? If someone's EA managed to open simultaneous multiple trades from different pairs accordingly, then, at least I know it is not the MQL4 code restriction.

That could be. I have no way of knowing. That is why I suggested contacting the original coder.

Another possibility is some kind of trading error which the code is not handling properly. Mohan suggests a trade context busy error. Others would be improper stops or insufficeint margin.

adding this to the end or beginning of the code won't hurt either when you are troubleshooting.

int error = GetLastError();
if(error != 0) Print(error);
