RuinRisk – Investment Risk Through the Lens of Ruin Probability RuinRisk helps traders and individual investors analyze investment risk through the lens of "risk of ruin." From three parameters — win rate, risk:reward ratio, and capital risk per trade — it visualizes risk using both a theoretical formula and Monte Carlo simulation, helping you make decisions based on numbers rather than gut feeling. Key features: • Ruin Probability Calculator (CALC): Shows both the theoretical (Balsara) value and a Monte Carlo–based estimate • Risk Heatmap (HEATMAP): See at a glance how risk changes across parameter combinations, with suggested improvements • Monte Carlo Analysis (ANALYSIS): Simulates drawdown probability. Evaluates risk from three distinct perspectives — Ruin Probability, Monte Carlo Analysis, and the Kelly Criterion — with recommendations tailored to each • Data Matrix (MATRIX): A full table of drawdown probabilities by trade count and drawdown level. Save and compare multiple plans, and export to CSV RuinRisk includes both a simple Legacy Mode and a more detailed Pro Mode. Pro Mode's advanced analysis features can be unlocked via in-app purchase. *The information provided by this app is an estimate for reference purposes only.
