Introducing RangeSight Studio: Monte Carlo for Every Trader
Why We Built RangeSight
RangeSight Studio is a Monte Carlo simulation app for iOS that runs 10,000 randomized trade sequences using real historical market volatility to calculate risk of ruin, survival probability, and drawdown distributions. Most retail traders evaluate strategies by looking at a single backtest curve. Institutions, by contrast, run thousands of simulations — a practice documented by Aaron Brown in *Red-Blooded Risk* (Wiley, 2011) as the standard methodology at firms like AQR and Citadel.
We wanted to close that gap.
What You Can Do
- Run 10,000 Monte Carlo paths using real historical volatility for any ticker
- See your survival probability across different position sizes
- Visualize drawdown curves showing P5, P50, and P95 scenarios
- Compare strategies side by side with different risk parameters
How It Works
Enter your win rate, risk per trade, and average R-multiple. Choose a ticker for real volatility data. RangeSight runs the simulation and shows you the distribution of outcomes, not just the average. Unlike spreadsheet calculators that assume constant volatility, RangeSight incorporates volatility clustering and fat-tailed distributions from actual market data.
What's Next
We're building more tools for serious traders. Follow the blog for articles on risk management, or try the free Risk of Ruin Calculator to get started.
Key Takeaway
RangeSight Studio brings Monte Carlo simulation to retail traders. See how it works and what makes it different from traditional risk calculators. RangeSight Studio uses Monte Carlo simulation to give traders institutional-grade risk analysis — 10,000 paths, real volatility, full drawdown curves.
This explains the concept.
But outcomes vary in practice. Test your strategy to see how consistent it actually is → Run survival test
