Understanding "Drawdown": Relative vs. Absolute Limits
In the world of proprietary trading, "Profit Target" gets all the glory, but "Drawdown" is the one calling the shots.
It is the most common reason traders fail their challenges. You might have a winning strategy, great psychology, and perfect execution, but if you misunderstand how your Prop Firm calculates drawdown, you can lose your account while you are actually in profit.
At PropW, we believe transparency is the foundation of a long-term partnership. Today, we are breaking down the math behind the "Game Over" line: Absolute vs. Relative (Trailing) Drawdown, and the crucial difference between Balance and Equity.
1. The Basics: What is Drawdown?
In simple terms, drawdown is the peak-to-trough decline of your account. It measures how much money you have lost from your highest point.
In a personal account, you can lose 50% and still keep trading (though it’s painful). In a Prop Firm Challenge, you usually have a hard limit (e.g., 10%). If your account equity touches this line for even a second, the account is breached.
But where that line sits depends on the type of drawdown.
2. Absolute Drawdown (The "Static" Floor)
This is the simplest and most trader-friendly form, though it is becoming rarer in the industry.
Definition: The loss limit is fixed to the initial starting balance. It never moves.
Example:
Starting Balance: $100,000
Max Drawdown: 10% ($10,000)
The Hard Stop: $90,000
If you make $5,000 profit (Balance: $105,000), your hard stop is still at $90,000. This means you now have a $15,000 buffer. As you grow the account, it becomes harder and harder to fail.
Pros: Great for swing traders; allows you to build a massive safety net.
Cons: Most firms view this as "low risk" for the trader eventually, so they often use...
3. Relative (Trailing) Drawdown (The "Moving" Target)
This is the industry standard for most modern prop firms. It is designed to protect the firm's capital and ensure traders practice consistent risk management.
Definition: The loss limit trails (follows) your account balance or equity as it grows. It moves up with your profits, but it never moves down.
Example:
Starting Balance: $100,000
Max Drawdown: 10% (Trailing)
Initial Hard Stop: $90,000
Scenario A: You profit $5,000.
New Balance: $105,000.
New Hard Stop: $95,000 (The limit trailed up by $5,000).
Your Buffer: Still $10,000.
The Trap: If you lose that $5,000 profit the next day, your balance is back to $100,000, but your hard stop remains at $95,000. You now only have a 5% buffer left, not 10%.
Key Takeaway: With Trailing Drawdown, you cannot "bank" volatility. You must protect your profits as aggressively as your principal.
4. The Hidden Killer: Balance vs. Equity Based
This is the detail that separates the "Pros" from the "Gamblers." Even if you understand Trailing Drawdown, you must ask: "Is it calculated on Balance or Equity?"
A. Balance-Based Drawdown (Trader Friendly)
The drawdown is calculated only on Closed Trades.
If you are in a trade that is up $2,000 (floating profit) and then it drops back to break-even, your drawdown limit does not move.
This allows you to let winning trades run without fear of being penalized for normal market breathing.
B. Equity-Based / High-Water Mark (Strict)
The drawdown is calculated on your Open Floating Profit.
Scenario: You buy BTC. It pumps, and you are up $5,000 floating profit. Your account Equity hits $105,000.
The Reaction: Your Trailing Drawdown immediately moves up to lock in that high-water mark.
The Crash: BTC retraces, and you close the trade at Break Even ($100,000).
The Result: You didn't lose money, but your Breach Level is now higher. You have lost $5,000 of your breathing room without booking a single dollar.
5. How to Adapt Your Strategy
Knowing the rules dictates your style.
If trading Absolute Drawdown: You can aim for home runs. Once you build a buffer, you can increase position size slightly.
If trading Trailing Drawdown: You must be a "Sniper."
Lock Profits: Don't let huge winners turn into losers.
Scalp More: Shorter duration trades reduce the risk of giving back floating P/L.
Understand the "Lock Point": Most trailing drawdowns stop trailing once you reach the starting balance (e.g., once your breach level hits $100k, it stays there). Your goal is to race to that point.
Conclusion: Read the Fine Print
At PropW, we design our rules to find consistent, profitable traders—not to trick you.
Before you buy any challenge, look at the FAQ. Don't just look at the price tag. A cheaper challenge with "Equity-Based High-Water Mark Trailing Drawdown" is mathematically much harder to pass than a slightly more expensive one with "Balance-Based Drawdown."
Know your limits, protect your downside, and let the upside take care of itself.
