Consistency Calculator — Prop Firm Trading Rules

The consistency calculator helps prop firm traders verify that their trading performance meets the consistency rules required by funded account programs. Most prop firms require that no single trading day accounts for more than 30–50% of your total profits — this ensures traders are not "lucky" on one day but consistently profitable. Enter your total profit and your best single day profit to instantly see your consistency score and whether you pass or fail the rule. Use this calculator throughout your prop firm challenge to stay compliant and avoid disqualification.

Consistency Calculator — Frequently Asked Questions

Q.What is the consistency rule in prop firm trading?

Most prop firms require that your single best trading day does not exceed 30–50% of your total profits. This prevents traders from passing a challenge by having one lucky day and losing money on all other days. It ensures your profitability comes from consistent, repeatable performance.

Q.What consistency percentage do prop firms use?

It varies by firm. FTMO uses a 30% rule for some accounts. MyForexFunds uses 40–50%. The Funded Trader uses 30%. Always check your specific firm's terms — this calculator lets you set your own limit to match any firm's rules.

Q.What happens if I fail the consistency rule?

Failing the consistency rule typically means you will not receive your payout or will be asked to continue trading until your overall performance becomes more balanced. Some firms will disqualify your account entirely. Always check consistency before requesting a withdrawal.

Q.How do I improve my consistency score?

Take smaller positions on high-conviction days so no single day dominates your P&L. Aim for similar profit targets each day. Avoid "revenge trading" or oversizing after a good day. A consistent equity curve with similar daily returns is the goal of professional prop trading.

Q.What is the FTMO consistency rule and how does it work?

FTMO's consistency rule requires that your single best trading day does not exceed a set percentage of your total profits. Typically, no single day should account for more than 40–50% of your total profit across the evaluation. This prevents traders from making one lucky large trade and withdrawing — it proves consistent skill. Use this calculator to check if your best day violates the rule before requesting payout.
