extra order placed

I have an issue with an EA I wrote. It seems to at times place an extra order. It has only been one extra order. It does not do it all the time. Is this a common issue with EAs? Perhaps someone knows the solution right off which would be very helpful. Otherwise I will post the code snippets that handle the order placement. The system allows one long position placed and one short position but checks for open trades before sending new orders. The extra order opened has the same open time as the first order. I wonder if there is a small delay from when the order is placed to when it is registered as open in MetaTrader?

That's a logical conclusion, but the answer is no. The EA will "lock" and wait for the OrderSend(...) function to return before continuing. This means that before the next line of code is executed the function will have either returned with an error or will have succeeded and the new order is accessible via OrderSelect(...).

You're not going to end up with temporarily unaccounted for orders.

Hmmm. I use the _IsTradeAllowed function as explained here: http://articles.mql4.com/141
I find that the 30 second wait is often exceeded before the trading context is freed. I wonder if this could have something to do with it?
I will try and clean up my trade management code sections to post.
Thanks Tesla.

My broker is FXDD. I didn't have this issue in backtesting. Wondering if anyone else with FXDD has had this problem?
