Blown prop firm account? Turn every failed evaluation into a rule
What to do after blowing a prop account: a four-line post-mortem (cause, what happened, lesson, rule), why repeated lessons matter, and real example rules.
The account is gone. The email from the firm is in your inbox and the reset button is right there. Before you click it, spend ten minutes on the one thing that makes a blown account worth what it cost: a lesson, written down and turned into a rule.
Here's what to do after blowing a prop account: write a four-line post-mortem. The cause (which rule ended it), what actually happened, the lesson in one sentence, and the rule you'll follow next time. Then check whether you've written that lesson before, because repeated lessons are the clearest signal your journal will ever give you.
The four-line post-mortem
- Cause: the rule that ended it, in the firm's words. Daily loss limit, trailing drawdown, max loss, consistency rule, or a rule break like trading news, holding overnight or going over the contract limit.
- What happened: facts, not feelings. Times, sizes, number of trades. "Down $400 by 10:05, took 4 more trades in 20 minutes, the last one at 3 contracts."
- The lesson: one sentence about you, not the market. "When I'm down early, I size up to get it back."
- The rule: something you can check with a yes or no at the end of the day. "After 2 losses, the day is over."
Write it the same day, after a walk, while the details are fresh but the adrenaline is gone. Four lines is enough. A long essay about how unfair the market was won't help you next time.
A blown account you learned nothing from is the most expensive kind.
A worked example
| Field | Example |
|---|---|
| Account | 50K evaluation, day 6 |
| Cause | Daily loss limit |
| What happened | Two losing trades on MNQ by 9:50 (−$420). Switched to 3 contracts to win it back. Hit the limit at 10:12 after 5 trades in 22 minutes. |
| Lesson | My losses come from trying to get the day back, not from my setups. |
| Rule | After 2 losses, the day is over. |
Notice the lesson isn't "NQ was choppy." The market is always doing something. A lesson that blames the market can't become a rule, because you can't control the market. You can only control what you do after the second loss.
Why repeated lessons matter most
One post-mortem is useful. Ten of them are a dataset. Line them up and count the causes.
A sample trader in our demo blew 28 prop accounts over 28 months. Blown accounts lasted 8 days on average. Here's how they ended:
| Cause | Accounts | Share |
|---|---|---|
| Daily loss limit | 10 | 36% |
| Trailing drawdown | 7 | 25% |
| Rule break | 4 | 14% |
| Max loss | 4 | 14% |
| Consistency rule | 3 | 11% |
Daily loss limit and trailing drawdown together ended 17 of 28 accounts, about 61%. Both are about how a bad day gets handled. So the fix isn't a new setup or a new firm. It's what happens after the second loss.
Here's the part most traders miss: if you've written the same lesson three times, it isn't a lesson anymore. It's a pattern your rules haven't solved. Either the rule isn't specific enough, or you aren't following it. Make it stricter, or make it physical: close the platform, walk away, or use your platform's own daily loss setting if it has one.
What each cause usually points to
The cause is the firm's label. The real lesson sits underneath it. Use this table as a starting point, then check it against what actually happened in your trades that day.
| Cause | What it often points to | A rule to try |
|---|---|---|
| Daily loss limit | Trading on after losses, revenge trades, sizing up to win it back | Your own daily stop at half the firm's limit |
| Trailing drawdown | Giving back open profit, or several green days followed by one big red one | A modest daily goal, and you stop once you reach it |
| Max loss | A run of bad days without cutting size | After two red days in a row, trade half size the next day |
| Consistency rule | One huge day that makes up too much of your total profit | Cap your daily profit target so no single day dominates |
| Rule break | Not knowing the firm's rules on news, overnight holds or contract limits | Write down the three rules that apply to you before day one |
Your own answer may be different. The point is to go one level deeper than the email from the firm, because "daily loss limit" describes how the account ended, not why.
Lessons that became rules
Three lessons from the sample trader's blown accounts, and the rules they turned into:
| Lesson | Rule it became |
|---|---|
| "Every account I blew in the afternoon, I was already up in the morning and kept going." | Done by noon. |
| "New accounts die fastest because I trade full size on day one." | Never more than 2 contracts on a new account. |
| "My worst days are one loss turning into six." | After 2 losses, the day is over. |
Each rule is short enough to put on a sticky note on your monitor. That's the test. If a rule needs a paragraph to explain, you won't remember it at 10:12 when you're down $420. How to turn a bad habit into a rule you'll keep has more on writing rules that stick.
Should you buy the next account yet?
Only after the rule is written, and ideally after you've followed it for a week of sessions on sim or a personal micro account. If you can't name what will be different, the next account will likely end the same way. The account is simulated, but the fee is real money.
If you're deciding between a reset and a fresh evaluation, reset or new account walks through the math. And after a blown account covers the full checklist before you buy again, including the questions to ask about your risk and size.
Keep every lesson in one place
Lessons scattered across notes apps get forgotten. Keep a single list with the date, the account, the cause, the lesson and the rule. Read it before you buy any new evaluation. It takes two minutes and it's the cheapest risk management you'll ever do.
In Market Matrix, Am I getting better? inside My Trading Journey has a Lessons from blown accounts section: why each account ended and the lesson you wrote, side by side. It's also where you can see how long your accounts last, from first to latest.
Lessons also show up as Turning points. When you've written one, the app compares the 60 days before with the 60 days after (once there are 20+ trades on each side and at least three weeks have passed) and shows whether things got better or worse after it. That tells you what happened after the lesson, not that the lesson caused it, but it's the closest thing to a scoreboard for your own rules.

The point of the post-mortem
You can't get the fee back. You can make sure the next account doesn't end the same way. Four lines, one rule, and a quick check for repeats. If you're stuck in the loop of buying and blowing, read why you keep blowing prop accounts next.
