Enter your account size, risk percentage, stop distance, and pip value to instantly calculate how many lots to trade. The daily loss limit field shows how many consecutive losing trades you can absorb before hitting your program’s daily cap — know this number before you enter any position.

How to Use This Calculator

Account size — your current evaluation or funded account balance in USD.

Risk per trade (%) — the fraction of your account you’re willing to lose on this trade. For evaluations, 0.5–1% is the defensible range: it lets normal losing streaks run without breaching your daily loss limit or maximum drawdown.

Stop-loss distance (pips) — the distance in pips between your entry and your stop-loss. This changes with every setup; always size from the stop, not the other way around.

Pip value per standard lot — for EUR/USD this is $10. For JPY pairs and others it differs; check your platform’s contract spec or use $10 as the default for major forex pairs.

Daily loss limit (%) — enter your program’s daily loss limit to see how many consecutive full losses you can take before breaching it. This is your practical circuit breaker; set your personal session stop at two to three trades fewer than the mathematical limit.

Position Sizing and Evaluations

Position sizing is the mechanism that converts your edge into a durable evaluation pass. A strategy with a genuine edge will fail an evaluation if the positions are too large — because normal losing streaks will hit the drawdown floor before the edge has time to assert itself. The calculator above does the arithmetic; the discipline is deciding in advance what size you will trade and not deviating from it mid-session.
