Trading Tools Comparison
Both TradingHabits and ChartWiseHub offer a free risk of ruin calculator. The real difference is whether you want one number back immediately from two inputs, or a simulated range of outcomes built from a fuller strategy profile.
TradingHabits and ChartWiseHub both publish a free risk of ruin calculator, and both point traders toward the same cluster of follow-up tools: an expectancy calculator, a drawdown recovery calculator, and a position size calculator. But the two risk-of-ruin calculators themselves work differently. TradingHabits' version uses the classic closed-form "gambler's ruin" formula: enter your win rate and your risk per trade, and it returns a single risk-of-ruin percentage instantly, assuming a 1:1 risk-to-reward ratio and a fixed size every trade. ChartWiseHub's version runs a Monte Carlo simulation, generating many randomized sequences of wins and losses from a fuller strategy profile (starting balance, win rate, average win and loss in R, an optional fee drag, risk per trade, trade count, and your own ruin threshold), then reports the percentage of simulated paths that crossed that threshold, alongside a spread of other outcomes like median ending balance and percentile results.
The comparison below is based on ChartWiseHub's own published risk of ruin calculator page as of mid-2026.
| TradingHabits | ChartWiseHub | |
|---|---|---|
| Price | Free, all calculators | Free, no signup found on the calculator page |
| Signup required | No account, no email, no login | No account required to use the calculator itself |
| Methodology | Closed-form "gambler's ruin" formula, one deterministic calculation | Monte Carlo simulation across many randomized trade sequences |
| Inputs | Win rate and risk per trade only, assumes a 1:1 risk-to-reward ratio and fixed position size | Starting balance, win rate, average win and loss in R, optional fee drag, risk per trade, number of trades, ruin threshold, simulation count |
| Output format | A single risk-of-ruin percentage | Estimated risk of ruin, probability of profit, median and average ending balance, median max drawdown, 10th-percentile outcome, expectancy per trade, break-even win rate |
| Best for | A fast, directional read on how win rate and risk per trade interact, without entering a full strategy profile | A fuller stress test that accounts for uneven win/loss size, trade-sequence risk, and a range of possible outcomes rather than one number |
Both sites point to nearly the same follow-up cluster for a reason: risk of ruin means more once it's tied to expectancy, losing-streak odds, and drawdown recovery math. A trader could get a fast directional read from TradingHabits' instant formula, then run the same strategy's fuller profile, uneven win/loss sizes and all, through ChartWiseHub's Monte Carlo simulation to see the range of outcomes behind that single number.
