Math, not promises
Calculators and simulators with real math — true Monte Carlo, compounding, percentiles. Free, in your browser, no signup or cookies.
A pretty backtest (green) rises on its own; the real ticks (red) cut through drawdowns that knock you out of the market. These tools measure that gap: risk of ruin, losing streaks, real costs and break-even with true simulation.
With your win rate, ratio and risk per trade: what are the odds you blow the account? 10,000 Monte Carlo simulations with the fan of possible futures.
Open calculator →The exact size in lots from your balance, your risk and your stop-loss. Forex, gold and more. Never over-risk by «eyeballing» again.
Open calculator →What are your REAL odds of passing a challenge (FTMO and similar) without breaching drawdown? See why the enemy isn't the target, it's the risk.
Open simulator →Lose 50% and you need +100% just to get back. The cruel math of big losses, with a reference table and clear bars.
Open calculator →How often must you be right to make money? It depends on your risk/reward ratio. Plus your system's real expectancy.
Open calculator →How your account grows over time and with contributions, with a chart. Plus a reality check: why trading returns aren't a fixed %.
Open calculator →What spread and commissions really take per month and per year, and what % of your account your strategy must beat just to break even.
Open calculator →How much to risk to maximise growth — and why full Kelly blows up accounts. With the honest recommendation of fractional Kelly.
Open calculator →How many losses in a row are normal for your win rate? Real Monte Carlo so you don't quit when the inevitable streak hits.
Open calculator →How much margin your trade locks given leverage, your free margin and how close you are to a margin call.
Open calculator →How much a pip is worth in your trade given the instrument and lots. The piece that translates the chart (pips) into your account (dollars).
Open calculator →Enter your real results and find your profit factor, expectancy per trade and R-multiple: whether your system has a real edge or just looks like it.
Open calculator →The tools help with YOUR manual trading. If you run an EA, the first thing is to know whether its edge is real. We measure that with real ticks in the validation service.
