Sorry, @Oxa!
I attached a example, in this particular case, it suposed to enter to win 100 (100/(back_price-1)), but he enter in to win 96,77, altering the loss, and maximising the lost, if it enter correctly, i would win 100, and the lost is much less...
I think thats is because the stop loss option activated... The is another way to fixate the win/lost in the especified value??
Thanks;
