Yes, this is the same error message indicating that your bets were taken before they could be cancelled. I'd recommend increasing the threshold for the Stop-Loss function, as obviously 2 ticks does not make it far enough for the bets to stay unmatched why the program is cancelling them.
Oh, just occurred to me: if there were some bets to cancel, how did they appear in the market? Did you place them manually outside the Auto-Greenup function or was the "Attempt to green up" option turned on after all?
