How to use this calculator
Adjust the inputs to your own scenario, then review the result alongside the assumptions below. The $ symbol is a currency label; the tool does not convert exchange rates.
Worked example
A $100 risk budget, 0.005 quote-price stop distance, and 1:1 conversion permit 20,000 base units (0.2 of a 100,000-unit lot).
The formula
Base units = floor(account risk ÷ (stop distance × quote-to-account conversion)). P/L = units × directional price move × conversion.
What the result means
Compare the output with the stated assumptions. Changing an input changes the arithmetic; it does not establish how a real trade or investment will perform.
Assumptions and limitations
Requires explicit currency conversion; USD labels represent your account currency. No margin checks, spreads, swap, commission, or changing FX rates. Does not constrain notional to account cash.
