How to Stop Blowing Prop Firm Accounts (It's Not Your Strategy)

I blew 3 accounts in 1 week (here's what actually happened)

I've told this story before on the about page, but the short version is worth repeating because I keep meeting traders who are doing the exact same thing I did.

Late 2021. I'd just passed three Apex evaluations. Felt invincible. Got funded, sat down at my desk with coffee and confidence, and started trading 10 contracts of MNQ on each account. My drawdown on each one was about $1,500.

Do you see the problem yet? Because I sure didn't.

NQ dropped 30 points that morning. At $0.50/point per contract times 10 contracts, that's $5 per point times 30 points = $150 of loss per contract. Wait, no. Let me redo that math because this is exactly the kind of sloppy thinking that got me into trouble. MNQ is $0.50/point, so 10 MNQ contracts = $5/point. A 30-point drop = $150 loss. Times three accounts = $450 total. Actually, that's not what blew them. What blew them was that I held through a 300-point move thinking it would reverse. $1,500 per account. Gone. All three.

Here's the kicker: NQ reversed that afternoon and ripped 60 points past my entry. The trade idea was completely fine. I just didn't survive the drawdown to see it play out.

That's the part nobody tells you. Most blown accounts aren't bad trades. They're bad sizing on decent trades.

The 3 real reasons traders blow funded accounts

After blowing those accounts (and a few more after that, because apparently I'm a slow learner), I started keeping a journal. Not a trade journal -- I already had one of those. A "why did I blow this account" journal. Very humbling reading. After about a dozen entries, a clear pattern emerged. It was always one of three things.

Reason 1: Oversizing (the big one)

This is responsible for probably 70% of blown accounts, and it's the one traders are most in denial about. Here's how it usually goes:

New funded trader gets a $50K account. Thinks "I can trade 10 NQ." The account says $50K, so 10 contracts feels reasonable, right? No. Your account size is irrelevant. Your drawdown is what matters. And on that $50K account, your drawdown might be $2,500.

Let's do the math. You're trading NQ with a 20-point stop. NQ is $20/point per contract. So each contract risks $400. At 10 contracts, you're risking $4,000 per trade. On a $2,500 drawdown. You literally cannot survive a single full loss.

Even at a more conservative 5 contracts, that's $2,000 per trade. One loser and you've used 80% of your drawdown. Two losers and you're done. That's not trading. That's flipping a coin with your account on the line.

The fix is simple math: figure out your risk per trade, divide your drawdown by that number, and that tells you how many losers you can survive. If that number is under 10, you're oversized. More on this below.

Reason 2: Ignoring drawdown type

This one is sneaky. Not all drawdowns work the same way, and most traders don't realize this until it's too late. I wrote a whole separate post on what drawdown actually means in prop trading, but here's the version that matters for not blowing your account:

Intraday trailing drawdown means your floor chases you upward. If you're up $500, your drawdown floor has moved up $500 too. Which means a winning trade actually reduces your safety buffer. Read that again. A winning trade on an intraday trailing account makes you closer to blowing it, not further away.

Most traders think "I'm up $500, I've got more room now." Wrong. On an intraday trailing account, you have the same room you started with (or less, depending on your high-water mark). The drawdown type fundamentally changes how much risk you can afford to take, and if you're treating all your accounts the same, you're going to get bitten.

Static drawdown? You actually do have more room after a win. EOD trailing? Your floor only moves at end of day, so intraday swings don't tighten it. Each type requires a different mental model, and frankly, different position sizes. If you're not sure what type your accounts use, go read the drawdown post before your next trade.

Reason 3: Revenge trading after a loss

Here's what happens. You take a loss. Maybe it was a good setup that didn't work, maybe you got stopped out on a wick. Either way, you're down $300 on a $2,500 drawdown. Not great, but not fatal.

Then the voice in your head says: "If I double my size on the next trade, I only need half the move to get back to even."

The voice is correct about the math and completely wrong about everything else. Because now you've got double the risk on a drawdown that's already 12% smaller. If this trade loses too, you're down $900 (the original $300 plus $600 at double size). That's 36% of your drawdown gone in two trades. One more average loser at the inflated size and you're done.

The math is cruel and it works against you: after a loss, your drawdown is smaller, which means you should be trading smaller, not bigger. If you lost 10% of your drawdown, you now need to be more conservative because your buffer has shrunk. The blow counter (next section) makes this painfully clear.

The blow counter: the simplest tool in trading

This is the thing I wish someone had shown me before I blew those first three accounts. It's embarrassingly simple, and that's what makes it powerful. You don't need a spreadsheet. You need one division:

Here's how to interpret the number:

• Under 5: You're gambling. This isn't trading, it's a coin flip with extra steps. One bad morning and you're done.
• 5-9: Danger zone. You might survive a normal losing streak, but anything unusual (a volatile news day, a string of stop hunts) will end you.
• 10-19: You'll survive most bad days. This is where serious traders live. A 10-trade losing streak is rare but possible -- at this level, you'd still have something left.
• 20+: You'd need a historically bad streak to blow this account. At 20+ consecutive losers, either the market is doing something unprecedented or your strategy is fundamentally broken. Either way, you'll have plenty of warning before it's over.

Let me put real numbers on this. Say you have a $3,000 drawdown and you're risking $200 per trade. Your blow count is floor(3000 / 200) = 15. That means 15 consecutive losers before you're done. With a 50% win rate, the odds of 15 losses in a row are about 0.003%. You're going to be fine.

Now take that same account but you're risking $600 per trade because you got a little aggressive. Blow count = floor(3000 / 600) = 5. Five consecutive losers. With a 50% win rate, that happens about 3% of the time. Trade long enough and it will happen. Not if, when.

FundedSizer calculates this automatically for every account in your pool. It color-codes the number too: green for 20+, yellow for 10-19, red for under 10. If you see red, reduce your risk before you trade.

My morning routine that stopped the bleeding

After the third or fourth blown account (I lost count, which tells you something), I forced myself into a pre-market routine. It takes about 90 seconds and it has genuinely saved me thousands of dollars in drawdown resets. Here it is:

1. Open each account and note today's available drawdown. Not yesterday's. Not what you think it is. Log in and look at the actual number. Trailing drawdowns move, and you need to know where your floor is right now.
2. Plug the numbers into FundedSizer (or whatever position sizer you use -- I'm biased, obviously). Enter each account with its current drawdown.
3. Set your risk to 1%. Sometimes 0.5% if I had a losing day yesterday. I know, 1% sounds tiny. It is. That's the point. You're trying to survive, not get rich on a single trade.
4. Check the blow counter on every account. If any account shows under 10, I reduce risk further until it's at least 10. Non-negotiable.
5. Write the contract count on a sticky note. Physical sticky note, on my monitor. Old school. Don't laugh -- it works because it removes the decision from the heat of the moment.
6. Do NOT change the size during the session. This is the hardest one. The sticky note says 2 contracts, you trade 2 contracts. Not 3 because you're "feeling it." Not 4 because the setup is "really clean." Two. All day.

I've been doing this for over a year now and I haven't blown an account since. My returns aren't spectacular. I'm not posting screenshots of $10K days on Twitter. But my accounts are alive, I'm collecting payouts, and I sleep fine at night. That's the whole game.

What to do after blowing an account

If you're reading this because you just blew an account: take a breath. It's not the end. Seriously. Every prop trader I know has blown at least one account. Most of the good ones have blown several. It's the cost of doing business in this weird little industry.

Here's what I'd do:

First, don't reset immediately. Take a day. The urge to buy another eval and "get back in" is strong, and it leads to the same mistakes because you haven't processed what went wrong.

Second, figure out which of the three reasons got you. Be honest. Open your trade log and ask:

• Was I oversized? (Check: what was my blow count on that trade?)
• Did I ignore my drawdown type? (Check: was the drawdown trailing, and did I treat it like static?)
• Did I revenge trade? (Check: did my size increase after a loss?)

In my experience, it's almost always #1 or #2. The strategy is usually fine. The position sizing is what kills you.

Third, when you do get back in, start smaller than you think you should. Your confidence is shaken and you'll be tempted to overtrade to prove you've still got it. Resist. Trade the smallest size that's worth your time and build back up over a week or two.

A blown account costs $100-$200 in eval fees. A lesson you actually internalize saves you that fee ten times over. Make sure you get the lesson.
