Prop firm EA consistency rule: calculate the best-day ratio

A prop firm’s consistency condition measures a defined distribution of results; it does not promise a smooth or profitable equity curve. An EA follows its code, but realised daily results still depend on the market, costs and execution. Start with the exact programme and account version, then calculate the ratio using that programme’s definition.

Identify the rule before configuring an EA

Save the provider, programme, evaluation or funded stage, order date, account mergers, measurement period, day boundary, numerator, denominator and consequence of an unmet condition. A profit target, minimum trading days, daily loss limit and best-day ratio are separate tests. Passing one does not satisfy the others. A platform’s generic “consistency score”, Sharpe ratio or smooth chart cannot replace the contractual calculation.

Do not assume that every firm applies a 30–35% cap or that a percentage limits the profit you may book in one day. The relevant condition might instead delay completion or reward eligibility until the required distribution is achieved. Provider permission for the exact EA, ownership, copying and trading methods needs a separate check.

FTMO: distinguish current 1-Step, legacy and Instant

Checked on 16 October 2026, the official CFD Trading Objectives set a 50% Consistency condition for the applicable 1-Step cohort: best closed-profit day divided by total closed profit across all days, including loss days. It applies to completing the 1-Step Challenge and reward eligibility on the corresponding 1-Step Account.

The 8 October transition notice specifies new 1-Step orders from 12 October 2026 at 09:00 MetaTrader platform time, GMT+3, and 1-Step Accounts merged on or after 12 October. Earlier orders retain the legacy Best Day Rule unless the relevant merger transition applies. Passing, a reward withdrawal or receiving a subsequent account does not alone change that legacy cohort.

Legacy uses a 50% limit against Positive Days’ Profit: sum each profitable day’s net closed result and exclude losing days from that denominator. Current 1-Step includes those losing days. FTMO Instant is separate and uses a 30% total-profit condition for reward eligibility. Do not transfer either formula to 2-Step or another provider. FTMO says exceeding these best-day limits is not itself a rule breach; the condition remains unmet until sufficient eligible profit is built. Loss limits and prohibited conduct still apply.

A daily ledger that exposes the difference

Fictional results in one account currency, not an EA forecast: assume these are already the provider’s eligible net closed daily figures.

The best day is 600. Current 1-Step gives 600/1,000 = 60%, above 50%. Legacy Positive Days’ Profit is 600 + 400 + 200 = 1,200, so 600/1,200 = 50%. The same history therefore satisfies that legacy ratio but not the current ratio. This is only one condition, not a pass or payout decision.

If the best day stays 600, a 50% total-profit condition needs total eligible net profit of at least 600/0.50 = 1,200. From 1,000 that is 200 additional net profit. At 30%, the algebraic total would be 600/0.30 = 2,000. These are conditional calculations, not profit targets to chase. A new larger best day or further loss changes the answer. A zero or negative denominator does not yield a meaningful satisfied positive-profit ratio; use the provider’s treatment and dashboard.

Reconcile the EA export with the provider

Group closed transactions by the provider’s day boundary. FTMO’s objectives use 00:00 CE(S)T; that is different from assuming your computer’s midnight or confusing the transition notice’s platform time with the daily cutoff. Reconcile commissions, swaps and adjustments under the provider’s definition; do not deduct a cost twice if the export is already net. Deposits, withdrawals and floating profit are not interchangeable with closed trading profit.

Retain transaction references, account currency, timestamps, rule version and the dashboard comparison. Check both the end-of-day figures and any point where the provider assesses other completed objectives. If the export disagrees with Account MetriX, resolve the difference before treating your own spreadsheet as eligibility proof.

What automation can and cannot change

Closing a 600 profit as 200 and 400 on the same eligible day still makes 600. Likewise, two pairs producing 300 each on that day contribute 600 together. More tickets, partial closes or adding strategies do not automatically reduce a daily ratio. Moving a close to another day changes market exposure and may conflict with other conditions; it is not a compliance shortcut.

Test any documented risk or pause controls on the exact file and platform, including restart, disconnection, missing costs and a changed day boundary. Pausing new entries does not close or protect existing positions. Diversification, smaller positions and stop orders can alter exposure; none guarantees a profit distribution, execution price or evaluation result. Avoid fitting parameters solely to make one historical ratio look acceptable.

The JPTC EA Hub concerns customer-operated software; verify each file’s documentation rather than assuming an automatic best-day monitor or universal firm approval. The separate JPTC Algo is hosted by JPTC: its customer installs or runs nothing and needs no VPS. Company-published broker-statement figures describe the stated Algo period, not an independent audit, EA Hub consistency test or customer challenge-pass study.
