The D'Alembert (cancellation) betting strategy for casino games (negative progression)

D’Alembert believed in the equilibrium of nature, suggesting that if an event happened more frequently than expected (for example 5 blacks in a row in Roulette) then the universe would balance itself by increasing the probability of red going forward.

The system is simple:

If you win an even money bet, you decrease the amount of the next bet by one unit.
If you lose, you increase the bet by one unit. This is based on the logic that wins make losses more likely, and vice versa.

Let us simulate this betting strategy to see whether it works.

Adjust the various winning ratios according to your game.
