I'm working on a Blackjack Strategies tester (in VB6).
One of the calculations I would like it to give is called Risk of Ruin or ROR.
ROR tells you the percentage chance of losing your whole bank roll before, say, doubling it.

Here's an example of some figures that might come up.
Bank Roll: 3000
Win/Loss Ratio: 96.84% chance of winning each session, or about 30 wins to 1 loss
Average Win Per winning session: $53.33
Average Loss Per losing session: $1,297.97

So can someone think of a formula to give the ROR?
