Risk warning. CFDs and leveraged FX carry a high risk of rapid loss; a majority of retail accounts lose money. Prop evaluations are paid products with rules that can end an account instantly. General information, not financial advice.
Ask someone who failed a prop challenge what went wrong and they will usually say "I couldn't hit the target."
Look at the account and it is almost never that. The target was reachable. What ended it was a rule — often one they had read once, understood loosely, and then breached at 3pm on a Wednesday while up on the month.
How an evaluation is structured
Most evaluations run in stages before any funding. A first phase (usually called the challenge) sets a profit target alongside daily and overall loss limits. A second, verification phase repeats the exercise on a lower target with the same kind of loss limits. Pass both and you reach the funded account, where there is usually no profit target to hit, but the loss limits still apply. The exact percentages differ from firm to firm, so take them from the rulebook of the firm you are considering rather than from an advert.
That structure is why the rules below matter more than the target: the target applies to two phases, the loss limits apply to all three, and breaching one, even once, typically ends the attempt.
Rule 1: daily drawdown — the account killer
Almost every evaluation has a maximum daily loss, typically a percentage of starting balance or equity. Breach it by a cent and the account is done, regardless of how profitable the month was.
Three details decide whether this rule is survivable:
When does "the day" start and end? Firms use different reset times, usually a server time you do not live in. A trade held across the reset is exposed to two daily limits.
Balance or equity? If the limit is measured on equity, an open, unrealised loss counts against you in real time — a trade that would have recovered can breach the limit before it does. If measured on balance, only closed losses count. This single distinction changes what strategies are viable.
Is it high-water-marked? Some firms measure the daily limit from the day's starting balance; some from the highest equity reached that day. The second is much stricter and catches people who give back an intraday gain.
Nearly every "unfair" prop-firm story turns out to be an equity-measured, high-water-marked daily drawdown doing exactly what the contract said it would.
Rule 2: overall drawdown — trailing or static
The maximum total loss. The critical question is whether it trails.
| Type | How it moves | Practical effect |
|---|---|---|
| Static | Fixed from the starting balance | Profits give you genuine breathing room |
| Trailing on balance | Rises with closed profits | Locked-in gains permanently raise the floor |
| Trailing on equity | Rises with unrealised highs | A spike you never closed can raise the floor against you |
Trailing-on-equity is the harshest common variant, and it is the one people misread most often. You can be up, close nothing, watch the position round-trip, and find your loss limit moved while you were not looking.
Rule 3: the consistency rule
A newer and much-misunderstood rule. It caps how much of your total profit can come from a single day or a single trade — say, no more than 30–40%.
The intent is reasonable: it stops someone passing an evaluation on one lottery ticket. The effect on honest traders is real too, because a legitimately excellent day can make an otherwise passing account non-compliant.
If your strategy is a small number of large winners, a consistency rule is not a detail. It is a strategy incompatibility, and you should filter firms on it before paying.
Rule 4: news, weekends and holding periods
Common restrictions that sound minor and end accounts:
- No trading during high-impact news, sometimes with a window of several minutes either side.
- No holding over the weekend, or over specified holidays.
- Minimum trading days, which prevents passing in one lucky session — and also prevents finishing early and stopping.
- Maximum lot size or exposure per instrument.
- No copy trading, no EAs, or restrictions on both. Automation rules vary wildly.
If a firm's documentation cannot answer those ten in under fifteen minutes, that is itself the answer.
Why the rules exist (and why that matters)
It is tempting to read the rulebook as a trap. Mostly it is not — it is a risk-management framework for the firm, and most rules map onto something a real trading desk would enforce.
The problem is asymmetry of attention. The firm has read the rules very carefully. The trader, having just paid a fee and feeling optimistic, has skimmed them. That gap, not malice, is where most failures live.
The fix is unglamorous: read the rules as though they are the strategy, because for the duration of the evaluation, they are.
How to trade an evaluation without breaching anything
Not trading advice — a description of what the rules structurally reward:
Size for the daily limit, not for the target. Work out the position size at which your worst realistic day is comfortably inside the daily loss cap, then trade that. The maths is in forex risk management and position sizing and understanding leverage and margin.
Know your reset time in local terms. Write it on a note. Do not hold across it while near the limit.
Do not aim to pass fast. Minimum trading days exist; speed buys nothing and costs risk.
Practise the rules, not just the strategy. A demo account with your own artificial daily limit is free — an AvaTrade demo costs nothing and lets you rehearse the discipline rather than the entry.

Frequently asked
What is the most common reason for failing a prop challenge?
Breaching the daily loss limit, particularly where it is measured on equity and includes unrealised losses. The profit target is rarely the binding constraint.
What is a trailing drawdown?
A maximum-loss level that rises as your account grows. On a balance-trailing rule it rises with closed profits; on an equity-trailing rule it can rise with unrealised highs you never locked in.
Do consistency rules apply to funded accounts too?
Often yes, and sometimes with different thresholds to the evaluation. Check both, because passing the evaluation under one rule set and then being funded under another is a common surprise.
Next: funded account or your own capital, costed over 12 months.

Frequently Asked Questions
What is the most common reason for failing a prop challenge?
The primary cause of failure is breaching the daily loss limit rather than missing the profit target. This frequently happens when accounts measure losses on equity, meaning open and unrealised losses count against the trader in real time and can end the evaluation instantly.
What is a trailing drawdown in a prop challenge?
A trailing drawdown is a maximum-loss level that increases as the account grows. Depending on the specific rules of the firm, it can rise with closed profits or, in the case of equity-trailing rules, with unrealised highs that were never actually locked in by closing the position.
Do consistency rules apply to funded accounts as well?
Consistency rules frequently apply to funded accounts, sometimes featuring different thresholds compared to the evaluation stage. Traders should check the rules for both phases, as passing an evaluation under one set of conditions only to face a different set when funded is a common surprise.
How does an equity-measured daily drawdown affect trading?
When a daily drawdown is measured on equity, open and unrealised losses count against your limit immediately in real time. This means a trade that might have eventually recovered can breach the maximum loss limit before it has the chance to turn around.
