RuinRisk
Risk of Ruin Calculator
$1.99
Instantly visualize your risk of ruin with simple sliders. Use heatmaps and Monte Carlo analysis to understand risk, validate strategies, and improve money management.
[Overview]
RuinRisk is a risk analysis app that helps visualize the “Probability of Ruin” in investing and trading.
With simple slider controls, users can easily perform risk evaluations without needing to understand complex calculations.
[Key Features]
■ Intuitive Probability of Ruin Simulation
Adjust parameters such as risk per trade, payoff ratio, and win rate to calculate the probability of ruin in real time.
Even without advanced mathematical knowledge, users can instantly understand the level of trading risk.
■ Heatmap-Based Risk Visualization
Display the distribution of probability of ruin using heatmaps based on the selected parameters.
This allows users to visually compare the risk balance of different strategies.
■ Practical Risk Analysis (Pro Mode)
Pro Mode provides access to more advanced analysis features.
• Risk analysis using Monte Carlo simulations
• Maximum expected drawdown estimation
• Drawdown probability analysis
• Insight-based risk evaluation summaries
These features provide more realistic risk assessments beyond simple theoretical values.
■ Calculation Methodology
The probability of ruin calculations in this app are based on mathematical models derived from money management and risk management principles.
Parameters such as win rate, payoff ratio, and risk per trade are used to evaluate long-term capital risk.
In Pro Mode, Monte Carlo simulations generate a large number of randomized trading scenarios to analyze more realistic drawdowns and risk distributions.
[What You Can Do]
• Check trading risk before entering positions
• Compare and evaluate trading strategies
• Improve money management practices
