Small interactive tools that do one thing and get out of the way. Calculators, converters, live charts.
Type entry, stop, and exit prices. Get the R-multiple — the gain or loss expressed as a multiple of the risk taken on the trade.
Slide your win rate. See the minimum reward-to-risk ratio your trades need before you start making money. Plus the inverse curve.
Type your account size, risk percentage, entry, and stop. Get the exact position size to take so a stop-out loses no more than the chosen percent.
