WORTH / KNOWINGKnow your room before you trade.
Estimate your remaining drawdown room and daily-loss room (static or trailing), then translate a buffered risk budget into an illustrative position size using your stop distance.
Enter the firm’s limits and your current account state to estimate what room remains.
Illustrative estimates only, not trading advice. Trading fees, funding, spread, and slippage reduce effective loss room when charged to the account; enter estimated round-trip costs above for position sizing, and include costs already posted in current/reset equity only once. Evaluation purchase fees are usually paid separately, so they do not reduce the program’s trading loss limit unless the firm’s rules or account mechanics explicitly charge them to that account. Firms may calculate limits from balance or equity, use different reset times, or apply trailing-floor rules differently. This estimate is not a leverage or margin recommendation.
Read the rule, not just the number.
Firms differ on whether limits use balance or equity, when daily limits reset, and how trailing floors move. This calculator uses your chosen assumptions to make the arithmetic visible; it cannot model every rule or predict losses. Compare the firm’s published calculation method before relying on any estimate.
