Strange trades being opened

 

Hi

Im trying to understand why my EA is opening these strange trades - see image.

I'm sure my EA would not - at least deliberately - open these trades, with these comments.

The comments allude to the trades being matched.

Strange Trades

Any ideas why these trades would occur?

 
With no code is impossible to guess... could you attach the EA?
 
It seems it opened 0.51 lot but it closed only 0.50. I suppose you killed the orphans manually, didn't you.
 
Your EA is closing partial positions and MT4 is re-assigning a new ticket number to the remainder of the trade
