Position Size Calculator
Position Size Calculator (PSC) helps size trades by dollar risk.
Set your Risk Amount ($).
Choose risk unit: ADR (avg high–low) or ATR (Wilder’s, gap-aware).
Shares = round(Risk $ / risk_unit).
Capital = Shares × current close.
Small table shows Risk $, Shares, Capital, and a mapped sector ETF (e.g., XLK, XLE).
Use ATR for gap-aware sizing; ADR for a simpler range. Adjust period to fit your stop style (shorter = more responsive). PSC is display-only (no orders), works on any symbol/timeframe, and updates on the latest bar.
