Hi, I am looking for suggestions about matters to be careful for in my EA, to open/close/modify orders together with security. As an example, what error handling should I do, and what other things should I program my EA to check to ensure I am doing such things safely (for example to guarantee it will not open orders with a dimension I did not need, and also to guarantee the order was received and executed by the host ). If you were able to show code which you use to open/close orders or merely give a few suggestions it would be fantastic. Thanks
