Could someone explain to me why my EA never executes simultaneous trades in different pairs. It can execute in all pairs but cannot do it simultaneously. Each time a trade opens in one pair, it stalls all potential trades with other pairs.

Here's the code that defines when to start the trade:

total=OrdersTotal(); // check the total active orders

for(count=0;count<total;count++) // if there are active totals then proceed
{
OrderSelect(count, SELECT_BY_POS, MODE_TRADES);
if(OrderType()<=OP_SELL && OrderSymbol()==Symbol() && (OrderMagicNumber()==MAGIC))
{
<code>: The code here is never reached if one order is open in a specific pair.

Thanks for your help in advance.

If you need the whole code, please let me know so I can send it to you by email.

Hi,

why do you have: if(OrderType()<=OP_SELL.....

??

this should be

if(OrderType()==OP_SELL.....

This means that only OP_BUY and OP_SELL are concerned, not the pendings.

I think the order takes a while to reach the brokers server and be verified there. This is only a guess. One ea I had was made to trade at exactly 12H00 - but could only do so on 2 currencies simultaneously else it got a 'dispatch busy' kind of error.
