I trade using robot and 2 weeks ago a couple of trades were executed by the robot as per normal (so I thought), however, they were kept open for the 2 weeks which is not normal for the robot I'm using. So I checked the log file and these two trades are not even in there, it's as if they don't even exist! I've been using this robot for a year and a half and this has never happened.
My question is, how is it possible that a trade was executed but was not logged in the log file? Could there be an issue with the broker MT4 or the robot itself?
