'sell (instead of buy)' in the log?

 
Hi,

In one of my EA's I've noticed a very strange entry in the log. See below:

09:00:03 Reversal QQE ADV EA(2) EURUSDFXF,H1: open #17943705 sell (instead of buy) 0.10 USDCHFFXF at 0.9977 ok
09:00:03 Reversal QQE ADV EA(2) EURUSDFXF,H1: Order executions slippage is -0.5131

The EA is running on EURUSD and opened a trade on USDCHF! This is very strange as this is not multi-currency EA and it sends orders only for the pair which it is attached. Moreover, notice the thing in parentheses - (instead of buy). I never seen this before. This is the log entry which is generated by MetaTrader terminal. Note the enormous slippage message of > 5000 pips!

Have anybody saw this before and/or know an explanation what is happening? My idea is that this is somehow broker related, so the broker is forex.com on demo account. Any pointer would be appreciated.

Regards,
Michal
