Drawdown
Definition
Drawdown is the percentage drop from an account’s peak value to a subsequent low before a new peak is reached.
What is drawdown?
Drawdown is the decline in a trading account, portfolio, or strategy from its most recent high-water mark (peak equity) to a later low point (trough), usually expressed as a percentage of that peak. In crypto trading risk management, drawdown is one of the clearest ways to describe “how bad it got” during a losing stretch, because it focuses on the fall from a prior best level rather than day-to-day volatility. For example, if your account rises to $10,000 and later falls to $8,500, the drawdown is 15% ($1,500 ÷ $10,000). Drawdown can be discussed at a single moment in time (current drawdown) or across a history of returns (a series of drawdowns), and it’s often paired with other risk metrics like the sharpe ratio to judge whether returns were worth the downside.
Max drawdown
Max drawdown is the single worst peak-to-trough decline observed over a chosen period for an asset, portfolio, or trading strategy. It answers the question: “What is the largest percentage loss I would have had to sit through before the account made a new high?” To compute it, you track the running peak value, measure each subsequent drop from that peak, and then take the largest of those drops. If an account goes $10,000 → $12,000 → $9,000 → $11,000 → $13,000, the max drawdown is 25% (from $12,000 down to $9,000), even though the account later recovered and made a new peak. Traders use max drawdown to stress-test sizing decisions—your position size determines how quickly a normal losing streak can become an unacceptable equity hit.
Portfolio drawdown
Portfolio drawdown measures the peak-to-trough decline of the entire portfolio’s equity curve, not just a single coin or one open trade. This matters in crypto because correlations can spike during market stress: several positions that look diversified can fall together, producing a larger portfolio drawdown than you’d expect from looking at each asset in isolation. Portfolio drawdown is typically calculated from the portfolio’s total value over time (including cash, spot holdings, and derivatives PnL), using the same peak-to-trough percentage method. It’s also sensitive to how you allocate risk across positions: two trades with the same stop distance can create very different portfolio drawdowns depending on leverage, concentration, and position size. In practice, many traders set a “maximum tolerable portfolio drawdown” (for example, a level at which they reduce exposure or pause trading) to keep losses survivable.
Why drawdown matters
Drawdown matters because it captures the real constraint most traders face: you can’t compound returns if you’re forced to quit, get liquidated, or lose confidence during a deep equity decline. Two strategies can have similar average returns, yet the one with smaller drawdowns is often more usable in the real world—especially when capital is limited and emotions are involved. Drawdown also connects directly to recovery math: after a 50% drawdown, you need a 100% gain just to get back to breakeven, so avoiding large drawdowns can be more important than chasing the highest upside. Used alongside the sharpe ratio, drawdown helps you distinguish “smooth” performance from performance that relies on enduring big drops. For more definitions and related concepts (like limits, stops, and sizing frameworks), see the risk management glossary, and remember that controlling drawdown is a core goal of crypto trading risk management.
Frequently Asked Questions
How do you calculate drawdown?
Drawdown is calculated as (peak value − trough value) ÷ peak value, usually expressed as a percentage. The “peak” is the highest account or portfolio value reached before the decline, and the “trough” is the lowest value reached before a new peak occurs.
What is the difference between drawdown and a loss?
A loss can refer to a single trade or a period’s negative return, while drawdown specifically measures the drop from a prior peak to a subsequent low. You can have losses without setting a new drawdown if your account is still above its previous peak.
What is a good max drawdown for a crypto trading strategy?
There isn’t one universal “good” number because it depends on the strategy, time horizon, and your risk tolerance. As a rule, smaller max drawdowns are easier to stick with and require less recovery, but they may come with lower returns or fewer opportunities.
Why is drawdown important for position sizing?
Position sizing determines how much your equity moves when a trade goes against you, which directly impacts drawdown. Oversized positions can turn normal volatility into large peak-to-trough declines, increasing the chance of liquidation or abandoning the strategy.
Is drawdown the same as volatility or the sharpe ratio?
No—volatility measures how widely returns fluctuate, while drawdown focuses on peak-to-trough declines. The sharpe ratio compares returns to volatility, whereas drawdown-based metrics focus on downside depth and recovery behavior.
