hi
it gets a bit complicated to use a bank per system.
like you said you have to use variables.
bank1
but then you have to link your selections index,bet amount and bet odds with variables.
you can only bet in markets that are a minimum of 10 minutes between start times, but the next bet can only be placed if the bank1 has been updated, so if there is a delay then no bets until the market is settled.
you also have to except the difference of .01 + - because of the calaculations.
