Trading Strategy Calculator
Read full descriptionHide full description
Before you risk real money, find out if your trading strategy actually makes mathematical sense. Trading Strategy Calculator turns your win rate, average win, average loss and costs into growth per trade, then runs a Monte Carlo risk report: 2,000 simulated runs that show whether your edge compounds, stalls or quietly bleeds out β and how deep the drawdowns get on the way. WHAT IT DOES β’ Risk report β one random run of your strategy, then 2,000 more that grow around it as bands, over 100, 1,000 or 10,000 trades: the range of outcomes, chance of profit, max drawdown, chance of a β20% drawdown, risk of ruin (a β50% drawdown) and the longest losing streak. Simulated from your inputs, not a forecast β’ Growth per trade β your edge before fees, what fees take, the break-even win rate and how many trades it takes to double or halve the balance β’ Fees + slippage β one round-trip cost per trade; enter it negative to model maker rebates β’ Compounding or flat stake β risk a percentage of a balance that moves, or the same dollar amount every trade β’ Until $1B β 2,000 runs that each go until $1B or bust (up to 1,000,000 compounding trades): the chance of getting there, the chance of going bust and how many trades it typically takes β’ Stop-loss and take-profit β exact prices from your entry and reward:risk ratio β’ Position size β your capital and risk % become the exact size of the next trade, with margin, leverage and a warning when liquidation would hit before your stop β’ Fee-aware sizing β add your round-trip fee and the size shrinks so a stopped-out trade loses exactly your risk, fees included; reward and R:R are shown net of fees β’ Simulate this setup β one tap loads the trade you just sized into the analyzer: win rate, average win, average loss and fees Everything above is free and stays free. KELLY CRITERION (PRO) Kelly turns your win rate and reward:risk, net of your round-trip fee, into the most your edge can justify risking per trade β a ceiling, not a target β and tells you to skip the trade when there is no edge. Full, Half and Quarter Kelly are one tap apart, it warns when your current risk is past what your edge supports, and one tap writes the size into your risk per trade. The Kelly ladder simulates 2,000 runs of 250 trades at Full, Half and Quarter Kelly and at your own risk, side by side: typical end balance, max drawdown and the chance of a β50% drawdown β so you see why a fraction of Kelly is the sane bet. Pro also includes two Pro app icons. Pro is a one-time unlock: buy it once, keep it forever. No subscription, no trial, no ads, no account. WHO IT'S FOR β’ Crypto and futures traders sizing the next position β’ Forex / FX scalpers stress-testing an edge before risking capital β’ Day traders and swing traders who want to know their drawdowns and risk of ruin before they live through them β’ Anyone curious whether their '60% win rate' actually compounds PRIVACY-FIRST β’ No accounts. No ads. No analytics. No data collection. β’ Everything runs on your device. Your strategy stays yours. Built by traders who got tired of finding out the hard way.
