Failing Prop Firm Evaluations Repeatedly: What's Actually Going Wrong

Failing one prop firm evaluation is ordinary. Failing three or more usually means the same thing keeps going wrong, and the account history will usually show what. The fix depends on which failure you have, so the first job is to sort them.

Sort every failure into a category

Pull up each evaluation and write down the exact rule or result that ended it. Then match it:

Category	What the log shows	First fix
A. One large loss	A single day or trade erased the cushion	Stops that are always live, hard daily limit
B. Slow bleed	Many small losses, no single disaster	Measure expectancy after costs
C. Ran out of time	Alive but short of the target	Size math against target and limits
D. Consistency rule	Target met, approval blocked	Cap your best day
E. Other rule	News, size cap, banned behavior	One page rules sheet

Applying the wrong fix wastes the next fee. A trader who bleeds slowly and answers with tighter stops just bleeds faster.

A: The single large loss

A loss that big almost always comes from a stop that was moved, removed or never placed. Make the stop part of the entry. In NinjaTrader 8, an ATM Strategy submits the stop and target with the entry, so there's no gap where you're in a position without one. Test it in a SIM account first and confirm on the order grid that the stop is working before you rely on it. How a stop is held (by your platform, your broker or the exchange) depends on the setup, so check that rather than assume it.

Even a live stop can slip in a fast market, so size positions as if some stops will fill worse than planned. Add a daily loss limit on top: stop trading for the day at a fixed dollar loss, written before the session. Some platforms and brokers offer an automatic limit. Check what yours does.

B: The slow bleed

Compare average winner to average loser, then subtract costs. Hypothetical: 55% winners at $120 and 45% losers at $100 gives $66 minus $45, or $21 per trade. At four trades a day for 20 days that's $1,680 gross. If costs are $5 per trade, it drops to $1,280. A small change in win rate or fills can turn the whole thing negative.

The honest check is a full log of entries, stops, targets and costs. If expectancy is negative or near zero in sim, an evaluation won't change that. It only charges you to measure it. Sim also flatters you, because simulated fills aren't exchange queue position or real slippage, so a positive sim result is a reason to keep going, not proof.

C: Out of time before the target

Here the size is mismatched to the target. Hypothetical: your average day nets 2 points on one MES. That's $10 a day, or $200 over 20 trading days. A $3,000 target needs about 15 times that size, roughly 15 MES. With an 8 point stop, 15 MES risks 15 x $5 x 8 = $600 per trade.

Now compare $600 to the firm's daily loss limit and drawdown, taken from its own rule document. If a few normal losing trades would breach it, the evaluation doesn't fit your current edge. Find a structure with a more reachable target relative to its loss limits, or don't take the test yet. Raising size just to hit the target recreates Category A.

D: The consistency rule

Rules differ by firm, so read how yours defines it. A common shape limits any single day to a percentage of total profit. Hypothetical: with a 30% limit and a $3,000 target, no day can exceed about $900 of profit at the time of review. One huge day followed by flat weeks fails it.

Keep size identical every session, and decide in advance to stop or cut size once you approach your best-day cap. It feels wrong to leave money on a good day. Passing the review is the objective of that session.

E: Other rule violations

These are the most preventable. Before opening an evaluation, write one page with the daily loss limit, drawdown type and amount, target, news restrictions with times (label the timezone), maximum position size, consistency parameters, and prohibited instruments or methods. Rules differ between firms and even between account versions at the same firm, and futures firms trading exchange products are not interchangeable with CFD style firms such as FTMO. Check the official rules page for the exact account you bought, and keep it visible during the session.

Before you pay for the next attempt

1. Keep a complete sim log for at least three months: every entry, stop, target and cost.
2. Compute expectancy after costs on at least 200 trades, and treat it as a screen, not proof.
3. Check stop compliance in the log. I'd want 95 clean trades out of 100.
4. Do the size math from Category C against the firm's actual limits.
5. Write the one page rules sheet and review it against the account's own terms.

You can test the expectancy math in the free edge calculator. Track every fee you pay as a cost line. If the total is climbing with no change in your process, the problem isn't the firm.
