TOTAL BETS IN PLAY AND THE AMOUNT

Create a variable "set user variable" name it maybe "Recoup" then use it as a true/false boolian-variable by setting it to Recoup=1 when the Recoup-trigger has been executed. You could then have a trigger-condition for the Recoup-trigger saying only execute trigger when Recoup=0.

Reset the Recoup=0 when the market has been settled. You would need conditions to mask out which hist_X_pl that comes from the recoup-trigger (it's a bit work).

I believe all this could be more easily solved by using variables for Min and Max balance? You would know if you have a recoup-potential if Max-Min>0.
