How the calculation works

The calculator answers one question: if my stop is hit, do I lose exactly the amount I chose to risk?

  • Any-market mode: units = money at risk ÷ (entry − stop). A $0.40 stop distance risking $100 means 250 units.
  • Forex mode: one standard lot is 100,000 units of the base currency, and a pip is 0.0001 (0.01 on JPY pairs). Lots = money at risk ÷ (stop in pips × pip value per lot).

Pip values are shown in the pair's quote currency. If your account is in a different currency the exact figure shifts with the exchange rate — the position size moves the same direction, so treat the answer as the honest starting point and round down.
