Position Size & R-Multiple Calculator & Lot Size Calculator
Calculates your lot size from a fixed percentage of account risk, so position size is never a decision you make in the heat of a setup.
Drag Entry, Stop Loss and Take Profit on the chart. The script returns the exact lot to trade, the dollar and percentage risk, the R:R, and a mechanical exit plan — all recalculating live as you move the levels.
What it shows
Lot size — derived from account balance, risk %, and stop distance. Always rounded down to your broker's lot step, so you can never accidentally size above your limit.
Risk in $ and % — turns red if the trade breaches your hard cap.
R:R — flagged if it falls below your minimum.
1R / 2R / 3R levels drawn on the chart, plus the exact half-lot to close at 1R and the breakeven stop that follows.
Verdict bar — a single green/orange/red line telling you whether the trade meets your own rules before you click buy.
Setup
Set your account balance and risk % once in Settings. Choose a contract preset (gold, silver, FX major) or enter a custom contract size. For non-USD-quoted symbols, set the quote conversion rate.
Why fixed risk
Inconsistent position sizing is what turns a run of small losses into a hole. Sizing every trade to the same percentage means your worst trade costs the same as your best one — and a losing streak stays survivable.
Not financial advice. This is a sizing tool, not a signal generator; it takes no view on whether a trade is worth taking.
