Why Most Prop Traders Fail: The Hidden Trap of Relative Drawdowns Explained

Many aspiring proprietary traders fail their evaluations not because they lack talent, but by misunderstanding one of the most crucial and least forgiving rules in the prop trading world: relative drawdowns.

While inexperience, poor discipline, over-leverage, and weak risk management all contribute to failure, misunderstanding relative drawdowns is one of the biggest reasons even profitable traders lose their funded accounts.

The Real Reason Many Prop Traders Fail

Prop firm evaluations are designed to assess a trader’s ability to make consistent profits while controlling risk. However, one rule often tilts the odds in favor of the prop firm, the relative drawdown rule.

Many traders enter an evaluation believing that as long as they don’t lose more than the maximum percentage from their starting balance, they’ll pass. But that’s not how it works. The drawdown limit is relative to your peak balance, not your initial one.

This means that as your account grows, your allowable drawdown level moves up,and so does your risk of breaching the rule.

Relative Drawdown vs. Absolute Drawdown

Relative Drawdown

A relative drawdown measures how much an account drops from its highest point (the “high-water mark”) to its lowest point.

• Formula:
  Relative Drawdown (%)=Peak EquityPeak Equity−Lowest Equity After Peak​×100
• This value changes as your account grows and falls, making it dynamic and harder to manage.

Absolute Drawdown

An absolute drawdown measures how far your account falls from the initial deposit—not from the highest point.

• Formula:
  Absolute Drawdown (%)=Initial DepositInitial Deposit−Lowest Equity​×100
• It’s static, meaning the maximum loss limit doesn’t change even if your account grows.

Example: How Relative Drawdowns Can Catch You Off Guard

Let’s say you’re taking a $100,000 prop firm evaluation with a 6% relative drawdown and a 10% profit target.

Starting Point:

• Initial balance: $100,000
• Initial max drawdown: $94,000 (6% of $100,000)

Account Grows:

You do well and grow your balance to $106,000.

Your new drawdown limit becomes:
$106,000 × (1 − 0.06) = $99,640

Now, let’s say you lose $4,000, bringing your account back to $102,000.

Even though you’re still up $2,000 overall, your maximum loss limit has now shrunk dramatically.

• You can only lose $2,360 more ($102,000 − $99,640) before breaching the drawdown rule.

If you hit that limit—even while remaining profitable—you’ll fail the evaluation.

Why Relative Drawdowns Favor Prop Firms

Relative drawdowns protect prop firms by tightening risk controls as traders make profits. However, for traders, this rule creates a moving target that requires active management.

Each time you make new highs, your risk cushion narrows unless you lock in profits or reduce position sizes. Failing to adjust your strategy can turn a winning streak into a failed evaluation.

How to Manage Relative Drawdowns Effectively

1. Track your high-water mark after every profitable trade.
2. Reduce trade size once you start achieving gains—protect what you’ve earned.
3. Avoid overtrading to recover small losses; this can quickly erode your remaining drawdown buffer.
4. Withdraw profits if the prop firm allows—this resets your risk level and locks in gains.
5. Use tighter stop-losses when approaching your relative drawdown threshold.

Understanding relative drawdowns can make the difference between passing and failing your prop firm evaluation. You can be a profitable trader and still fail if you don’t actively manage your account in line with this rule.

Before joining any prop firm, make sure you understand how drawdowns are calculated, how they move with your equity curve, and how to manage them effectively.

Because in prop trading, it’s not just about making money. It’s about keeping your account alive long enough to do so.
