hi
you could make a trigger to do it, 3 triggers in all
1 to set a variable per market to 0
1 to set a variable per market to 1 when there is at least 1 matched back bet and the amount of matched back bet equal the matched lay bets
1 to distribute the profit choosing the selection with the most profit, set to no more than 0.10
this keeps distributing the profit until all are in profit, sorry but not all profits are high some could be as little as .01 and others a lot higher.
