The Math Behind the FTUK Consistency Rule
The FTUK consistency rule uses: Consistency % = (Best Day Profit ÷ Total Profit) × 100. It must stay ≤20%. One oversized winning day fails even when you hit the profit target.
Exact mathematics behind FTUK's consistency requirement — and how to stay compliant while passing fast.
The Formula
Consistency % = (Largest Single-Day Profit ÷ Cumulative Profit) × 100
FTUK requires this ratio to stay at or below 20% on funded payouts and many challenge verifications. Consistency requirements on funded account payouts.
Worked Example
Suppose you are up $4,000 total and your best day contributed $1,200. Consistency = (1,200 ÷ 4,000) × 100 = 30%. That fails a 20% rule even though you are profitable.
Fix: cap each day at roughly 1/5 of running total profit until the distribution evens out.
Why Traders Fail This Rule
Hero days feel like success but mathematically guarantee payout rejection.
Revenge trading after a red day creates a second spike day when recovery comes too fast.
Oversizing after a win streak concentrates gains into one session.
- Set a hard session stop in dollars, not just R-multiples
- Log cumulative profit before every new entry
- Use Prop Survival to simulate pass paths with capped daily gains

How do I lower my consistency score after a spike day?
Stop trading until additional smaller green days increase total profit without adding to the best-day numerator. Alternatively, cap every session prospectively using the 7-Day Playbook profit caps.
