Why Most Traders Fail Prop Firm Challenges (And It's Always Drawdown)
You pass the profit target. You're 2 days away from getting funded. Then one bad trade wipes out 15% of your account. Challenge failed.
Sound familiar? It happens because most traders don't understand the two metrics that prop firms use to track your risk: maximum drawdown and relative drawdown.
Here's the truth: prop firms don't care how much money you make. They care how much you lose. Their entire system is built around drawdown limits. If you don't understand these numbers, you're trading blind.
Let's fix that. Right now.
What Is Maximum Drawdown? (The Dollar Amount That Ends Your Challenge)
Maximum drawdown measures the largest dollar decline from your account's peak equity to its lowest point during a specific period.
Think of it this way: your account grows to $110,000. Then a losing streak drops it to $95,000. The maximum drawdown is $15,000 — the biggest loss from your highest point to your lowest point.
Here's the formula:
Maximum Drawdown ($) = Peak Equity − Trough Equity
Real example using EUR/USD:
You start with a $100,000 prop firm account. After 3 winning trades, your equity hits $108,500. Then you take a bad trade — EUR/USD drops 80 pips against you on 0.5 lots. Your equity drops to $104,500.
Maximum drawdown so far: $108,500 − $104,500 = $4,000
Most prop firms set a maximum drawdown limit of 6-10% of your starting balance. On a $100K account, that's $6,000 to $10,000. Push past that, and your challenge is over.
What Is Relative Drawdown? (The Percentage Your Prop Firm Actually Cares About)
Relative drawdown measures the same thing — but as a percentage of your peak equity. This is the number that prop firms use to enforce their rules.
Formula:
Relative Drawdown (%) = (Peak Equity − Trough Equity) ÷ Peak Equity × 100
Same example, different view:
Peak equity: $108,500
Trough equity: $104,500
Relative drawdown: ($108,500 − $104,500) ÷ $108,500 × 100 = 3.69%
Here's why this matters more: your account grows, so the percentage changes. A $4,000 loss when your account is at $108,500 is 3.69%. But if your account peaks at $115,000 and you lose $4,000, it's only 3.48%.
Prop firms track relative drawdown because it scales with your account size. A 5% relative drawdown on a $200K account is $10,000. On a $50K account, it's $2,500. The percentage stays fair.
Maximum Drawdown vs Relative Drawdown: The Comparison Table
| Feature | Maximum Drawdown | Relative Drawdown |
|---|---|---|
| What it measures | Largest dollar decline from peak to trough | Percentage decline from peak equity |
| Unit | Dollars ($) | Percentage (%) |
| What prop firms use | Starting balance-based limits (e.g., 8% of initial) | Peak equity-based limits (e.g., 5% of peak) |
| Scales with account growth? | No — fixed dollar limit | Yes — percentage adjusts as equity grows |
| Example (100K account) | $8,000 max loss from starting balance | 5% max loss from peak equity |
| Best for | Tracking absolute risk exposure | Comparing performance across accounts |
The Wrong Way vs The Right Way (Real Trade Example)
The Wrong Way:
You have a $100K prop firm challenge. Your relative drawdown limit is 6% ($6,000). You take a trade on GBP/USD at 1.2650. You set your stop loss at 1.2580 — 70 pips. You trade 1 standard lot.
70 pips × $10 per pip = $700 risk per trade
You take 3 losing trades in a row: $700 + $700 + $700 = $2,100 loss. Your equity drops to $97,900. You're still within the 6% limit. But then you take a revenge trade — 2 lots this time. GBP/USD drops another 50 pips.
50 pips × $20 per pip = $1,000 loss
Total loss: $3,100. Your equity is now $96,900. You're still under $6,000 — but barely. One more bad trade and you're done.
The Right Way:
Same $100K account. Same 6% relative drawdown limit. But this time, you calculate your risk properly.
You decide to risk no more than 0.5% per trade. That's $500 per trade. You trade EUR/USD at 1.0850. Your stop loss is 25 pips.
25 pips × $10 per pip = $250 per standard lot. To risk $500, you trade 2 standard lots. But that's too much size. Instead, you trade 0.5 lots: 25 pips × $5 per pip = $125 risk per trade.
You take 5 losing trades in a row: $125 × 5 = $625 loss. Your equity is $99,375. You're still at 0.625% relative drawdown. You have room to breathe. You can take 48 more losing trades before hitting your 6% limit.
That's the difference between gambling and trading.
How To Calculate Both Drawdowns In 30 Seconds
Step 1: Track Your Peak Equity
Log into your trading platform. Find the highest equity your account has ever reached. Write it down.
Step 2: Track Your Trough Equity
Find the lowest equity point after that peak. This is usually after your worst losing streak.
Step 3: Do The Math
Maximum Drawdown = Peak − Trough
Relative Drawdown = (Peak − Trough) ÷ Peak × 100
Step 4: Compare To Your Prop Firm Rules
If your max drawdown limit is $6,000 and your current drawdown is $3,500, you have $2,500 of room. If your relative drawdown limit is 6% and you're at 3.5%, you have 2.5% of room.

FAQ
Is maximum drawdown the same as relative drawdown?
No. Maximum drawdown measures the dollar amount lost from peak to trough. Relative drawdown measures the same loss as a percentage of the peak equity. Prop firms often use both.
What is a good maximum drawdown percentage?
Most professional traders aim for 5-10% maximum drawdown. Prop firms typically set limits at 6-10% of the starting balance. Keeping your drawdown under 5% shows strong risk management.
Can I recover from a maximum drawdown?
You can recover your account value, but the maximum drawdown metric stays recorded. Prop firms track the largest peak-to-trough decline — not just your current balance. Even if you recover, that drawdown number is permanent.
Which drawdown do prop firms care about more?
Most prop firms use relative drawdown as their primary rule because it scales with your account growth. But many also enforce a maximum drawdown limit based on your starting balance. Read your challenge rules carefully — both matter.
📝 Quick Recap
- Maximum drawdown = largest dollar decline from peak equity to trough equity
- Relative drawdown = percentage decline from peak equity — the number prop firms enforce
- Prop firms use both to protect their capital. You must track both to protect your challenge
- Risk 0.5-1% per trade to keep your drawdown manageable. On a $100K account, that's $500-$1,000 per trade
- Your action item: calculate your current maximum drawdown and relative drawdown right now
Your Quick Win
Open your trading platform. Look at your account history. Find your highest equity point and your lowest equity point after that. Calculate your maximum drawdown in dollars. Then calculate your relative drawdown as a percentage. Write these numbers down. Compare them to your prop firm's rules. If you're close to the limit — stop trading and evaluate your strategy. If you're under 3% — you're doing well. Keep going.
