Not so sure this would work.

Lets say we lay selections in the $50 - $100 range and have a 99% strike rate.

5000/SR = 52 which would fail on 1 loss.

Perhaps if your laying to lose an amount it would work ok.

For example

5000/SR = 52 per 1 unit. So to lay to lose $100 you would need at least 5200 bank.
