I've always found it hard to answer questions like: How much bankroll do I actually need for the risk I'm comfortable taking? What's a realistic range of outcomes over the next year? How bad could the drawdowns get? What's the probability that I actually reach my bankroll goal? How much does my win rate / variance / volume change the picture? So I built Poker Bankroll Risk Engine to answer those questions with actual simulations rather than just a generic bankroll rule.
