What Is Drawdown in Trading?

So, what is drawdown in trading, and why does it matter more than a single losing trade?

A drawdown is the decline in the value of a trading account, investment portfolio or asset from a previous peak to a subsequent low. It measures the distance between the highest level your equity reaches and the lowest point it falls to before returning to that peak.

Understanding what is drawdown in trading also means recognising that a drawdown is not simply one losing trade. It usually reflects a sustained period of falling equity that can test both your risk controls and your ability to make disciplined decisions.

For retail CFD traders, understanding drawdown is a core part of what is risk management in trading. Contracts for Difference (CFDs) use leverage, which means losses and drawdowns can build quickly. How you manage them can determine whether your account survives a losing period or reaches a margin close-out level.

Quick Takeaways

• Definition: What is drawdown in trading? It measures the decline in capital from a previous peak to a subsequent trough.
• Floating vs realised: Floating drawdown reduces available margin even before a position is closed.
• Asymmetrical recovery: A 50% loss requires a 100% gain to return to the starting balance.
• Trading costs: Wider spreads and overnight fees can deepen a drawdown even when the market moves only slightly.
• Behavioural risk: Large drawdowns can lead to panic selling, revenge trading and other emotional decisions.

How Does Drawdown Work in Leveraged Trading?

Once you know what is drawdown in trading conceptually, the next step is seeing how it is usually expressed as a percentage of the account's peak equity.

For example, suppose your trading account rises to £10,000 and then falls to £8,000 before recovering to £10,000.

• Account peak: £10,000
• Account trough: £8,000
• Calculation: (£10,000 − £8,000) ÷ £10,000 = 20%
• Drawdown: 20%

The drawdown remains open until the account’s equity rises above the previous peak. Any further losses while equity remains below that level contribute to the same drawdown period.

Floating vs Realised Drawdown

Retail traders sometimes focus only on closed losses when thinking about what is drawdown in trading, overlooking floating, or unrealised, drawdown.

Realised Drawdown

Realised drawdown occurs when losing positions are closed, permanently reducing the account balance.

Floating Drawdown

Floating drawdown reflects losses on positions that are still open. These losses may change as market prices move, but they still affect the account’s real-time equity.

In leveraged CFD trading, floating drawdown creates a direct operational risk. A trader may decide to keep a losing position open, but the broker continues to calculate margin using the account’s current equity.

As floating losses increase, they reduce the amount of usable margin. Under FCA rules, retail CFD providers must close out a client's position once their funds fall to 50% of the margin needed to maintain their open positions — a protection designed to prevent losses from exceeding what the account can absorb (see the FCA's confirmed CFD restrictions).

What Is Maximum Drawdown?

Once you understand what is drawdown in trading at a basic level, the next concept to grasp is Maximum Drawdown, often shortened to MDD, which is the largest peak-to-trough decline recorded over a particular period.

While an account may experience several smaller drawdowns, MDD identifies the deepest historical fall. Traders often use it to assess the risk profile of a strategy, portfolio or trading system.

Maximum Drawdown Example

• Start: £10,000
• Peak 1: £15,000
• Trough 1: £12,000 — a 20% decline
• Recovery
• Peak 2: £20,000
• Trough 2: £10,000 — a 50% decline
• Recovery
• Peak 3: £25,000

The account’s Maximum Drawdown is 50%.

MDD shows the worst decline a strategy has experienced historically. However, it does not guarantee that future losses will remain within the same limit.

A strategy may show strong long-term returns while also carrying a Maximum Drawdown of 60%. Anyone using that strategy would need to accept the possibility of losing more than half of their account equity during difficult market conditions.

Why Is Recovering From a Drawdown So Difficult?

Anyone asking what is drawdown in trading should also understand why recovering from one becomes progressively harder as the loss increases, simply because the remaining capital base is smaller and must generate a larger percentage return to recover the original amount.

For example, an account that falls from £10,000 to £5,000 has lost 50%. To return from £5,000 to £10,000, it must then gain 100%.

In practice, many traders do not fully appreciate that after a 50% drawdown, repeating the same percentage performance that preceded the loss will not restore the account. The remaining capital must double simply to return to the previous peak.

This is why protecting capital is generally more important than trying to maximise returns.

How Do Spreads and Overnight Fees Affect Drawdown?

Part of understanding what is drawdown in trading is recognising that it does not result only from unfavourable market movements — trading costs can also reduce equity and make recovery more difficult.

1. Bid-Ask Spreads

The bid-ask spread is the difference between the price at which you can buy an asset and the price at which you can sell it.

When you open a trade, the spread means the position usually begins with a small floating loss. This cost may be larger when trading volatile markets or during periods of low liquidity.

If spreads widen sharply around major news releases or outside the most active trading hours, they can deepen a floating drawdown immediately.

2. Overnight Fees

An overnight fee may be charged or credited when a leveraged CFD position remains open after the trading day ends.

The fee is usually calculated using the full nominal value of the position rather than only the margin deposited. If a losing position remains open for several days or weeks, these charges may build up and reduce account equity further.

As a result, overnight fees can deepen the drawdown and increase the return needed to reach break-even.

How Can Drawdown Affect Trading Psychology?

Beyond the numbers, what is drawdown in trading also has a psychological dimension that can place traders under considerable emotional pressure, often leading them to abandon their normal risk rules precisely when those rules matter most.

Revenge Trading

Revenge trading happens when a trader tries to recover losses quickly by increasing position sizes or opening low-quality trades.

With leveraged products, this behaviour can accelerate losses and increase the risk of reaching a margin close-out level.

Panic Liquidation

Panic liquidation occurs when a trader closes positions because of fear or exhaustion rather than because the original trading plan has been invalidated.

In some cases, this may mean closing a position near the lowest point of a market move and realising a large loss shortly before prices recover. However, there is no guarantee that a recovery will occur.

Recognising drawdown as a normal statistical feature of trading can help traders respond more calmly. It does not remove the risk, but it can reduce the likelihood of impulsive decisions.

How Can Traders Manage Drawdown?

Since no risk-management method can remove what is drawdown in trading completely, traders can take steps to limit its effect instead.

• Use smaller position sizes.
• Set a maximum amount of capital to risk on each trade.
• Avoid holding too many highly correlated positions.
• Monitor both account balance and real-time equity.
• Include spreads, commissions and overnight fees in risk calculations.
• Set a maximum acceptable drawdown for the overall strategy.
• Reduce exposure after a series of losses rather than increasing it.
• Review whether a drawdown reflects normal strategy behaviour or a breakdown in market conditions.

Once you understand what is drawdown in trading, it follows that any drawdown limit should be based on the trader's financial circumstances, risk tolerance and strategy, not chosen only from historical returns.

What Is the Difference Between Drawdown and Loss?

A common point of confusion when learning what is drawdown in trading is how it differs from a simple loss.

Understanding what is drawdown in trading also means seeing how it relates to, but is not identical with, a simple loss: a loss describes a reduction in value, often from a single trade or group of trades.

For example, a trader may lose £200 on one trade without creating a significant drawdown if the account remains close to its highest value. Several losses in succession may create a much deeper drawdown.

Is Drawdown Always a Sign of a Bad Strategy?

So, is drawdown in trading always a sign of a bad strategy? No — almost every trading strategy experiences periods of drawdown.

The more important questions are:

• How deep is the drawdown?
• How long does it last?
• Is it consistent with the strategy’s historical behaviour?
• Can the trader continue following the strategy without exceeding acceptable risk?
• Has the underlying market environment changed?

A strategy becomes more concerning when the drawdown is much deeper or longer than expected, or when the trader no longer understands why it is occurring.

Conclusion

In short, what is drawdown in trading? It is the decline in a trading account's equity from a previous peak to a subsequent trough, and one of the clearest ways to assess the risk of a trading strategy.

For retail CFD traders, drawdown has practical consequences. Floating losses reduce available margin, while spreads and overnight fees may deepen the decline. Because larger losses require increasingly large gains to recover, protecting the account’s capital base is an important part of long-term risk management.
