Dear all,
I'm developing EAs by processing OnTradeTransaction events. Everything ran fine until tomorrow when an opened position was stopped after price reaching SL. Through my logs I verified my EA received an TRADE_TRANSACTION_DEAL_ADD event twice. To clarify (and facilitate my debuging processing), I simultaneouly ran a simple EA in a different timeframe (in parallel with the EAs I developed) that captured all events happening in MT5 (it is attached in this topic).
The events captured by this simple EA are here:

These results were extracted from a MT5 client provided by Five Percent Online Ltd (www.the5ers.com) - I suppressed other log messages to emphasize the problem. It is important to mencioned that I ran the same environment (EAs, Indicators, scripts) in other MT5 clients (the one you download from official MT5 website, the one provided by FTMO Global Markets Ltd (www.ftmo.com), in parallel way (same time, same machine, different accounts) and I did not observed such behavior.
My question is: is it possible to have duplicated events coming from the server? In what circunstance this happens? Do I need to check additional information from this deals to differentiated them?
I could expect missing events in high load environments due to the size of the MT5 client event queue, but duplicated messages?
Thanks in advance.
