only 1 trade at a time

Can someone plz help me. I need the code that will allow only 1 trade of a particular currency pair at 1 time. In other words...if my ea buys EURUSD...I do not want any more trades of the EURUSD until my first trade concludes.

Thanks in advance for the coding that I'm looking for.

The ea will trade several different currency pairs.

I tried the following code...but it would then only allow 1 total trade. I want more than 1 trade at a time I just dont want more than 1 trade at a time of the same currency pair.

Here is the code....

int total

total = OrdersTotal();

Then I added "total < 1" in my conditional listing. I'm stumped...anyone have an idea?

int allOrders=OrdersTotal();
orderOpen = false;
for(int pos=allOrders-1;pos>=0;pos--)
{
if(OrderSelect(pos,SELECT_BY_POS, MODE_TRADES))
{
if ((OrderSymbol() == Symbol() && OrderMagicNumber()==MAGICBB) && (OrderType() == OP_BUY || OrderType() == OP_SELL)) // can be simplified
{
// Have found an open automated order for this pair.
orderOpen = true;
// add your code here ....
}
}
} // end for

I added your code and then I added a line to my comment string so as to return the value for allOrders. It compiled just fine...but the value that was returned was 3.

There were 3 open orders going at the time....a USDJPY order...a EURJPY order and a GBPJPY order.

A value of 1 is what I was looking for because there is only 1 open order with each pair. The EA attached to each of the 3 currency pairs all returned a value of 3 for allOrders.

I appreciate your help....seems like the code you worked up is very close to what I'm looking for.

You are not interested in the count of all orders. You want to know if an order has been opened for the pair that the EA is running on. That is what orderOpen will tell you. Or did I misunderstand something?

Yes...you are correct. So should I set the first orderOpen to true?

The logic I gave is correct. Assume that no order is open until it has been confirmed inside the loop. There are any number of reasons the order could have been closed outside the EA ie. manual intervention, hitting the SL/TP.
