Thank you for the help.

Lets say that I bet $ 4 with ratio 2.0 (the ratio is constantly changing according to the card that appears now, assume first card).

Then I want to bet on the second card in $ 8 that includes the $ 4 profit.

Suppose second card appears at a ratio of 1.3 profit together are so 8 times 1.3 gives 10.4.

How do I calculate the total price up to the card that appears now ?

How do I calculate the total profit including the initial bet at each round ?

Thanks
