The mistakes that blow a prop firm challenge
A challenge is rarely lost on a bad chart read. It is lost on a size that is too big, a revenge trade, a chased signal or a stop you touch after placing it. The six mistakes my trading journal asks you to tick, what they do to the account, and the ones I made during my Apex evaluation.

These are not analysis mistakes
On an evaluation account, the loss threshold is the one thing that does not forgive. A wrong analysis costs a stop, planned and sized. What blows an account is straying from the plan: it turns a planned loss into an unplanned one, or a bad day into the last day.
The site’s trading journal lets you tick six mistakes after each trade. The table shows what each one does to the account and the counter I apply. I leave aside each firm’s own rules (trading hours, news, consistency of gains): they are in the article on passing a challenge, and above all on the firm’s own site.
| Mistake ticked | What it does to the account | The counter |
|---|---|---|
| Size too big | Two or three losses reach the threshold | Risk computed on the room left |
| Overtrading | A bad day becomes the last one | Number of trades set before the session |
| Off plan | A loss nothing justified | No signal, no confirmation: no trade |
| Entered too early | A stop hit before the move starts | Wait for the confirmation |
| Moved the stop | Widened: a bigger loss than planned | The stop never moves away |
| Exited too early | Does not blow it, but lengthens the challenge | Management decided before the entry |

Size: two losses, and it is over
Take a $50,000 account with a $2,000 drawdown. At 2% of the account per trade, each full loss costs $1,000: two in a row are enough to reach the threshold. That was my risk during the evaluation, for instance 16 MNQ with a 31.25-point stop on September 28, so $1,000. It held, but with no reserve at all.
The right denominator is not the balance shown, it is the room to the threshold, and it moves every day. The table counts the full losses possible on a fresh account. On the funded account, I moved down to 1%.
| Risk per trade | Full loss | Losses in a row before the threshold |
|---|---|---|
| 2% | $1,000 | 2 |
| 1% | $500 | 4 |
| 0.5% | $250 | 8 |

Revenge: my October 1
On Thursday, October 1, 2026, a Nasdaq short closes in profit, then a gold short is stopped out. At 08:36, New York time, I buy 7 MNQ after an indicator signal given at 07:25, more than an hour earlier, without a real confirmation. Cut 30 points lower. The journal records that trade at −$428.30, fees included, with the “Off plan” mistake.
The day ends at −$1,005.02 and I have $994.98 left above the threshold. That trade was not analysis: it was the urge to end the session green. My counter since: the number of trades is set before the open, and a dented room cuts size instead of adding a trade.

Chasing a signal that left without you
On Tuesday, October 6, 2026, the indicator gives a buy on the Nasdaq at 04:30, with the CISD (change in state of delivery) and a 5-minute FVG just above. I wanted to take it; price left without me, all the way to the target. This time, I did not chase it.
It is the same situation as October 1, with the opposite decision. Entering far from the signal means a wider or flimsier stop for a move that has already happened. A missed signal costs nothing; the same signal chased can cost a day. The next day, I waited for the next one.

The stop, in either direction
Widening your stop as price closes in means deciding, in the middle of a loss, that the planned risk is no longer enough. That is the mistake that turns a 1% loss into a 3% one, and on a prop firm account, the one that reaches the threshold fastest.
The other way, moving it up too early does not blow the account, but it slows it down. On September 28, I brought three trades back to break-even; one of them then went on to its target without me. A challenge that lasts longer means more sessions, so more chances to make the mistakes above.

Where the indicator comes in
FTS Liquidity Sweep Pro spots liquidity sweeps and shows its signals, with their time. It draws neither stop nor target, and it knows nothing about your account: size, the number of trades and management stay your decisions. What it changes is the starting point. Every trade has a signal time, which makes “Off plan” and “Entered too early” checkable after the fact.
On October 1, the gap between 07:25 and 08:36 can be read on the chart. On October 6, so can the signal that left without me. No indicator prevents a revenge trade; it only makes visible the moment you left the plan, and that is what the journal then counts.
