Load a sample trade and watch every calculator answer at once: size, margin, liquidation, reward to risk, costs, Kelly, drawdown and risk of ruin. Change the numbers to test your own plan.
Each calculator answers one question. A trade raises all of them at the same time: the size depends on the stop, the margin on the leverage, the leverage on the liquidation, the whole plan on whether the win rate and payoff hold up over a run of trades. The simulator puts them side by side so you can see which one fails first.
Try the over-leveraged scenario to see a stop that sits beyond liquidation, and the losing-streak scenario to see how a plan that looks fine on one trade behaves over a long run. Nothing is sent anywhere: the numbers stay in your browser.
Questions people ask
Is the data real?
No. The scenarios are invented round numbers chosen to show how the calculators behave. They are not market data, signals or a recommendation.
Can I use my own numbers?
Yes. Change any field and every result updates. The simulator runs entirely in your browser and nothing is sent to a server.
What is the downloadable app?
A single HTML file with all the calculators and this simulator. It runs offline in any browser. It is free with a subscription to the channel.
