hi
i am still working on it, the main problem is getting the profit and loss correct for each bank.
when one bank lay bets and the other back bets in the same market, they can both win or both lose or one win and one lose.
so one bank has to take in to account the other banks profit or loss, so that it can calculate the correct commission deduction, so if one bank wins 4 euro and one bank losses 2 euro, it is only commission on 2 euro not 4 euro, so one bank has to deduct the 2 euro then deduct the commission on 2 euro then add the 2 euro back to the profit.
