Spread the word onHow does a consistency rule work?
A consistency rule caps how much of your total profit can come from your best day. Under a 50% rule, your best day must be no more than half of your total profit when you pass. On a $3,000 target that means no day above $1,500, if you want to pass at exactly the target.
Say your first four days are +$420, +$1,350, −$310 and +$720. That’s $2,180 of profit, and the $1,350 day is 62% of it: over the limit for now. You still need the $3,000 target, so $820 more. One more day between $820 and $2,180 passes you: $820 brings you to $3,000, where $1,350 is 45%, and at $2,180 that new day is exactly half of your $4,360 total.
Why can one big day hold you back?
A big day raises the total you need. Make $2,500 on day one of a 50% plan and you need $5,000 of total profit before you can pass, not the $3,000 target. At MyFundedFutures going over doesn’t fail the evaluation; you just trade more days until the best day is a small enough share. That’s why the calculator shows Today’s Cap: up to it, a good day leaves the total you need where it is.
What is the blown line?
The blown line is the balance at which the account hits its maximum loss. On an end-of-day trailing plan it sits the max loss below your best closing balance, so it rises as you make new highs and never comes back down. Room to Lose is the gap between your balance and that line. MyFundedFutures lists no lock on it during the evaluation; its +$100 lock applies only in the funded stage.
Common questions
How do you work out a consistency rule?
Divide your best day by your total profit. Under a 50% rule the answer must be 50% or less when you pass, so a $1,350 best day needs at least $2,700 of total profit - and the plan’s target, if that is higher.
Do losing days count?
The calculator counts your net profit: winning days minus losing days, as your account balance shows it. A losing day lowers your total, so your best day becomes a bigger share of it.
What happens if one day is too big?
At MyFundedFutures, going over the consistency limit doesn’t fail the evaluation. You keep trading until your best day is a small enough share of your total profit, so a very big day raises the profit you need before you can pass.
