Strange stop loss execution

New comment
 

I have an EA that places 2 trades with size 0.1  with the same stoploss

Running in Strategy tester

The trade hits stoploss  a while later    with a sell of 1.4 lots.

Where the heck did the size 1.4 come from???  Must be missing something vital in my code or what?

Multiple deals on the same symbol combine to become one position . . . perhaps you had 14 x 0.1 lot sell deals on EURUSD ?  we can see 2 in the log excerpt you posted . . .  
 

Just found that out. Thanks anyhow.

Takes time to get the new way of order handling into the mindset. Working on porting a rather complex EA of mine from MQL4 to MQL5.
