Consistency Rule
Designed to filter gamblers, or grind you down?
What it is
A consistency rule limits how much of your total profit can come from a single trade or a single day. Typical implementations: no single day can account for more than 30-40% of your total profit, or your best day can't exceed X% of your account.
Why it exists
Firms want to fund traders with repeatable edge, not gamblers who got lucky once. A trader who makes their entire 8% target in one massive trade is statistically more likely to blow up eventually than one who averages 0.5% per day consistently.
Ignore what any firm's rule says. Check your own numbers first, then go find a challenge shaped like the way you actually trade, not the other way around. Enter your two values below to find your consistency score.
FYI: don't use hypothetical inputs, use your own, there's no judgement here. SwingFish's own data currently sits at roughly 10.6% consistency, tracked live in the trading room.
Firms word this rule differently, but the math behind it is always the same ratio. Enter a stated threshold and your best single day, and see what it actually demands before you've traded a thing.
*This is a floor, not a plan. It only holds if every qualifying day happened to land at exactly the maximum the rule allows, which real trading doesn't produce on demand. Use it to tell whether a claimed pass is mathematically possible, not as a daily target to chase.
What does your number mean?
It means nothing, by itself. It's just your trading's volatility expressed as one number, there's no good version or bad version. If your number comes in under whatever a firm requires, it has zero effect on you, you'd never even notice the rule existed. If it comes in over, nothing went wrong either, it just means: keep trading, keep making money, and get paid later instead of now.
How to "fix" your consistency to meet a Firm's Requirement
You don't fix this by changing what already happened, you can't, and you shouldn't want to. If a genuine, once-in-a-while opportunity shows up, take it. The profit is yours regardless of what it does to this ratio, nobody claws back money you actually made. All that's left afterward is to calm back down: keep trading normally, without letting a future day beat that new peak, and let the total grow underneath it. Every ordinary day added past that point pulls the percentage down by itself, because the same peak is now a smaller slice of a bigger total.
The relationship is the same days-floor math as the other tab, just run in reverse: cut your percentage in half and you roughly double the day-count floor underneath it. That sounds like a cost, but it isn't one. That stretch isn't dead time spent waiting for a number to improve, it's ordinary trading, and if the edge is real, you're making money through all of it. There's no sacrifice here, only time you were going to spend trading anyway. A consistency rule is only a genuine obstacle for someone trying to rush a pass off a single outsized trade with nothing behind it. For anyone trading a real edge, a monster day is a good day to have taken, not a mistake to avoid for fear of the ratio, just something to settle back down from afterward.
The two sides
The firm's argument
It filters for real skill vs. luck. Consistent traders are more likely to stay profitable long-term, which is better for both the firm and the trader.
The trader's reality
Consistency rules are a daytrading problem, specifically. Swing and position traders lean on a handful of large, well-timed trades, that's not luck, it's what the style looks like when it's working, and a rule built around daily activity punishes them for trading correctly. If that's you, trade a product without a consistency requirement instead of bending a sound strategy to fit one.
Ceiling rules vs. floor rules
Run the numbers above on FTMO's 50% and it comes out to a 2-day floor: at worst, you'd only need two good days to clear it, best case. That's not an oversight, it's the point. A consistency rule phrased as a ceiling, "no single day above X%", is built to catch one specific edge case: someone passing the whole challenge off a single oversized bet. Trade across even a modest number of days with normal position sizing and a loose ceiling like 40-50% essentially never comes into play. It's a tripwire for gamblers, not a constraint on ordinary trading.
Some firms build the same math into a floor instead: not "no single day may exceed X%," but "you must produce at least this many qualifying days, this size, within this window, or you don't get paid." Minimum profitable days rules are the clearest version of this. The arithmetic is identical, a day-sized percentage measured against a reference balance, but the practical bite is not. A ceiling only punishes an extreme, rare pattern. A floor has to be actively cleared, on schedule, by trading that's otherwise completely normal, a legitimately disciplined trader having a quieter stretch, fewer but larger wins, a slower month, can miss a floor without doing anything wrong. Before accepting a "consistency requirement," check which shape it actually is.
FTMO does this the right way, and the numbers make an easy trap to fall into: its equivalent rule asks for 7 green days against Blue Guardian's 5, a bigger number that looks like a stricter requirement. It isn't. FTMO's version has no minimum percentage attached, just green, which rewards good position management and active loss recovery, clawing a bad session back to breakeven still counts, instead of demanding an artificial daily profit target on top of the challenge's actual target. A bigger day count is not a higher requirement. One version measures whether you can trade. The other measures whether you can hit a number.
