You have to think of this long term like stocks or buying a racehorse with out the purchase cost and other fees.

When we add a runner to the stable it is like buying the stock, we don't have a result until one of three things happen.

1) Runner wins paying more than $3 this would result in a profit.
2) Runner wins returns less than what is need for a profit.
3) Runner has 7 starts since being added to stable or is sent for a spell resulting in a loss.

Overall we need to be in front but i will not calculate this on a daily basis but more looking at the number of open trades compared to the number of winning and losing trades.

This is why i would not like to see say 80 open trades and maybe 15 winning and 5 losing trades as this would put a big strain on the overall bank.

Right now each new runner added to the stable needs 19 units of the bank allocated to it so right now i have room for about 50 open trades, i don't think i will need the full units allocated for each runner but this is the way i have it set up right now.
