Topic: Error in execution operation: Invalid Ticket. What happened?

Note: I post this under the Strategy builder column.  Realised it should be under Strategy Trader column instead and hence I post this again.

Hi, whenever my strategy tried to place an order, eg. EurUSD Entry Order Sent with SL=0 but TP=1.35xx etc. 

3 minutes later, I get this message in the Strategy Trader journal -Error in operation execution: Invalid ticket.

And the order that was initially sent and executed, was closed and hence made a loss 3 min later when the error message came in.

Could you kindly advice me what went wrong and how can i correct this problem.

Thanks

Regards
Hannah

Can you attach the strategy in the forum for test? What broker do you use?
