Why it exists
Without a minimum day count, an evaluation could be passed by putting the whole account on one trade. Some would pass; most would not; the firm would learn nothing about either group. Requiring four, five or ten trading days forces a sample that means something.
It is one of the few rules that is straightforwardly in your interest as well as the firm's, because it filters out exactly the behaviour that destroys funded accounts.
What counts as a day
This is where firms differ and where people get caught:
- A closed trade on that day — the most common definition.
- Any open position during the day, including one carried over from yesterday. More forgiving.
- A minimum result — a few firms require the day to have produced some minimum profit or volume, which is much stricter.
Also check whether the day is defined by the firm's reset hour, which is the same boundary discussed in daily loss limits and reset times. A trade closed at 23:50 your time may fall on a different calendar day for the firm.
The awkward case: target hit early
You reach the profit target on day two of a required five. You now have three days where you must place trades but have nothing to gain and an account to lose. This is where evaluations are most often thrown away.
The sensible approach is to reduce risk to a token level. Place the minimum size that qualifies, take the setup only if it is the best one you see, and accept that the objective for those days is survival rather than profit. You have already passed; you are just waiting for the calendar.
Some traders reverse this and trade larger, reasoning that they have a cushion. That cushion is the thing that gets you funded. Under a trailing drawdown it is also the thing that has already raised your breach level.
Weekends, holidays and thin sessions
Days on which the market is closed do not count, which can stretch a five-day requirement across two calendar weeks around a holiday period. If your evaluation has a time limit as well — increasingly rare, but check — that interaction matters.
Thin holiday sessions are also poor conditions for forced trading. If you need days and the market is dead, taking a small position in a liquid instrument to register the day is a reasonable use of the rule, provided the firm's definition allows it.
On funded accounts
Some firms carry a minimum-day requirement into the funded account, usually as a condition for a payout rather than for keeping the account. If so, it interacts with the consistency rule: you may need both a minimum number of days and a distribution of profit across them.
Check both before you plan a payout request.
