Hi Oxa,
Someone from your support team has put me straight with this:
IF(AND(consec_losses<=5,losses_1>0),back_size*2,InitialBet)
and it seems to be working fine.
My next question is how to stop the trigger when it reaches a certain profit then reset the profit to zero at say midnight? So in a nutshell it makes a set profit each day and restarts at midnight.
