Prop Firm Consistency Rules Explained: How the 50% Rule Works

What a consistency rule is

A consistency rule limits how much of your result can come from a single trading day. It exists because an evaluation is supposed to measure a repeatable process, and one oversized winning day tells a firm very little about whether you can do it again next week.

It is also the rule traders understand least. Most people learn the loss limits on day one, because breaking them ends the account. The consistency rule rarely ends anything, so it gets skimmed, and then it shows up as a surprise when the profit target looks hit but the evaluation has not passed.

This guide covers the two common ways firms calculate it, how ours works in dollars, and how to plan a pass around it.

The two common versions

Firms word their consistency rules differently, but most fall into one of two families.

A cap measured against the profit target. No single day may contribute more than a fixed share of the target. The target never moves, so the cap is a fixed dollar figure you can write down before your first trade. This is the version Funded With Forex uses.

A cap measured against your total profit. No single day may be more than a fixed share of all the profit you have made so far. Here the cap moves with your results. One big day raises the total you need before that day stops being "too big", so the finish line moves further away the better your best day was.

Some firms use a variation that looks only at profitable days. FTMO, for example, describes a Best Day Rule: no single day above 50% of profitable days, per FTMO's published rules (verified 2026-08-10). Others state no rule at all on some plans: FundedNext lists no striking system on the plan we compared, per FundedNext's published rules (verified 2026-08-10). Always read the exact wording on the firm's own page, because the same "50%" can mean very different things.

How the 50% rule works at Funded With Forex

On every evaluation, no single day can make up more than 50% of your profit target. Three details matter:

• It is measured against the target, not your running total. On a $50K one step evaluation the target is $5,000, so the most any one day can count is $2,500. That number is fixed from the moment the account opens.
• Going over the cap does not breach you. The account stays open and the profit stays in your balance. The part above the cap simply does not count toward passing.
• It only applies to evaluations. Once you are funded there is no consistency cap at all.

Because no single day can count for more than half, every pass takes at least two profitable days. That pairs with the minimum of 2 trading days on the one step, both listed on the evaluation rules page.

Worked example: a big first day

Take a $50K one step evaluation. The target is $5,000, and no day counts for more than $2,500.

• Day 1: +$3,200. Counts as $2,500. The extra $700 is real profit in your balance; it just does not count toward the target.
• Day 2: +$1,500. Counted total: $4,000.
• Day 3: +$1,000. Counted total: $5,000. Target reached.

Your balance is up $5,700 and you passed on day three. The big first day did not hurt you. It meant the target took one more day than the raw numbers suggested, nothing more.

Now run the same week under a cap measured against total profit, also at 50%. After the $3,200 day, your total profit would have to reach at least $6,400 before that day stops being more than half of it. You would need $3,200 more from other days, not $2,500. The bigger your best day, the further the finish line moves.

That is the practical difference between the two families. Under a target based cap, the finish line is fixed. Under a total based cap, it moves with your best day.

Worked example: the 2 step

The 2 step evaluation applies the same 50% cap in both phases, each measured against that phase's own target.

On a $100K 2 step, Phase 1 has an 8% target of $8,000, so no day counts for more than $4,000. Phase 2 has a 5% target of $5,000, so the cap drops to $2,500 a day. Traders who size up after clearing Phase 1 are working against a smaller cap, which is backwards. If anything, Phase 2 rewards smaller, steadier days.

Why firms use it, and why it is not a trap

From the firm's side, the evaluation is a measurement. A single outsized day is the signature of a trade sized far beyond a sensible risk budget that happened to work. The consistency rule asks for a second and third data point before treating that result as skill.

From the trader's side, the cap lines up with good risk management anyway. If your plan risks 0.5% to 1% per trade, a single day producing half of a 10% target means you made 5% in one session. That is possible, but it usually means the position size was bigger than the plan. Traders who stick to the position sizing formula rarely meet the cap at all.

How to plan a pass around it

• Write your cap down before day one. Divide the target by two. On a $25K one step that is $1,250, on a $50K it is $2,500, on a $100K it is $5,000 and on a $150K it is $7,500.
• Treat the cap as a great day, not a goal. Hitting it is a strong session. Chasing it is how traders breach the 3% daily loss limit.
• Stop adding risk once you are near the cap. Profit above it does not move you closer to passing, but a loss still comes out of your balance and out of your daily loss allowance. Extra size above the cap is all risk and no progress.
• Check your consistency share on the dashboard. Vera Charts shows it live next to your distance to target, daily loss used and max loss floor, updated with every fill.

What changes once you are funded

Nothing caps your best day on a funded account. One strong session can be your whole month.

What remains is the payout eligibility rule: to request a payout you need at least five qualifying days, each with $250 or more of realized profit. It is not a consistency cap, but it does mean a single big day on its own will not unlock a payout. The payouts page and our explainer on how prop firm payouts work cover the full cycle, and the funded forex account guide lists every rule for every account size in dollars.

How other firms compare

Consistency rules are one of the least standardised parts of this industry, which is why we put the wording side by side rather than a single yes or no. Our FTMO comparison quotes their Best Day Rule in full, and the comparison index covers the other firms we track.

Common questions

Can the consistency rule fail my evaluation? No. Exceeding the cap never breaches an account. Only the daily loss limit and the max loss floor end an evaluation, both explained in our drawdown rules guide.

Does the cap change with account size? The percentage is the same at every size. The dollar figure scales with the target: half of a 10% target is $1,250 on a $25K and $7,500 on a $150K.

Is there a consistency rule on the funded account? No. It only applies during evaluations, on both the one step and the 2 step.

Does a big day slow me down? Only slightly. Under our rule, the profit above the cap still sits in your balance, and you need other profitable days to finish the target. Plan for at least two or three good days rather than one great one.
