Drawdown in Forex Trading: A Comprehensive Guide to Understanding Risk

Losing money in a trading account is unavoidable. However, what makes a difference is how well you understand and manage drawdown. Drawdown is not just a number showing losses; it’s a crucial risk management indicator and a key to building sustainable trading strategies. When you truly understand drawdown, you can make smarter decisions and significantly reduce the risk of financial failure.

What is Drawdown You Need to Understand

Drawdown refers to the decline in your trading account balance from its peak to its trough during a period of consecutive losses. To clarify, imagine you start with 10,000 THB. After several losing trades, your balance drops to 8,000 THB before recovering. In this case, your drawdown is 2,000 THB.

Why is drawdown important? Because it reflects the real risk you face in the market. Higher drawdowns indicate you need better risk management skills, while lower drawdowns show you can preserve your capital more effectively. It also helps you assess whether your trading strategy is stable.

The 3 Main Types of Drawdown Traders Should Watch

Relative Drawdown: Percentage Perspective

Relative drawdown shows the decline as a percentage of your highest account balance. The calculation is: (Peak - Trough) ÷ Peak × 100.

For example, if your account grows from 10,000 THB to 20,000 THB but then drops to 15,000 THB, the relative drawdown is (20,000 - 15,000) ÷ 20,000 × 100 = 25%.

This type is useful for comparing performance across accounts of different sizes. A high relative drawdown indicates higher risk, while a lower percentage suggests better risk management.

Absolute Drawdown: From the Starting Point

Absolute drawdown measures the monetary loss from your initial deposit. Even if your account grows, this value shows how much you have lost in total. For example, if you start with 10,000 THB and your balance drops to 8,000 THB, the absolute drawdown is 2,000 THB.

This helps determine how much you need to recover to break even. The larger the absolute drawdown, the more effort required to bounce back.

Historical Drawdown: Lessons from the Past

Historical drawdown is the maximum decline your account has experienced historically. It shows how low your account has gone in the worst-case scenario. This information helps you understand the market volatility you need to prepare for.

If your historical drawdown is 30%, you should be prepared to face similar declines again.

Floating vs. Real Drawdown: What’s the Difference?

Equity Drawdown: Real-Time Risk

Equity drawdown measures the current reduction in your account balance, including open (unclosed) trades and closed losses. If your balance drops from 10,000 THB to 9,000 THB before recovering, the equity drawdown is 1,000 THB.

This is important because it reflects the real-time risk you are facing. Monitoring equity drawdown helps you decide whether to close trades now or wait.

Floating Drawdown: Unrealized Losses

Floating drawdown refers to the loss from open trades that are not yet closed. “Floating” means it’s not a realized loss until you close the trade. It fluctuates with market movements.

For example, if your account was 10,000 THB and drops to 9,000 THB due to open trades, the floating drawdown is 1,000 THB. If the market reverses before you close, the floating drawdown can disappear. That’s why timing your decision to let trades run or close is critical.

How to Control Drawdown to Protect Your Capital

Set a Drawdown Limit from the Start

This is the most important step. Decide on the maximum percentage of drawdown you’re willing to accept before stopping trading. For example, you might choose to stop and reassess if your drawdown reaches 10%.

Setting this limit prevents you from trading blindly and losing too much money.

Use Stop Loss for Every Trade

A stop loss is a predetermined price level to close a trade if it moves against you. Using stop losses limits your losses per trade. When the market moves unfavorably, your trade will close automatically at the set level, helping you avoid large drawdowns.

Decide Your Risk Percentage per Trade

Determine how much of your account you’re willing to risk on a single trade. The common rule is risking no more than 2% per trade. For example, if your account has 100,000 THB, you shouldn’t risk more than 2,000 THB on one trade.

This approach ensures that a single loss doesn’t significantly impact your overall account.

Use Risk-Reward Ratio

Before entering a trade, set a risk-to-reward ratio, typically 2:1. This means aiming for twice the profit compared to the potential loss. For example, if you risk 100 THB, aim for a 200 THB profit.

Maintaining this ratio helps ensure your winning trades outweigh your losing ones, reducing overall drawdown.

Take Profits When Appropriate

As your account grows, consider withdrawing some profits. This protects your gains from market reversals or unexpected events, helping preserve your capital over the long term.

Drawdown and Emotional Management in Trading

One major mistake that worsens drawdown is revenge trading. When traders experience losses, frustration and anxiety can lead them to trade impulsively to recover losses. These impulsive trades often lack a clear plan and can cause even larger drawdowns.

Discipline and a solid trading plan are essential. If you suffer significant losses, pause, analyze what went wrong, and revise your strategy. Managing your emotions effectively is the best way to combat drawdown.

Summary: Understanding Drawdown and Its Importance

Drawdown is an inevitable part of Forex trading, but you can manage and control it through good planning and discipline. Understanding different types of drawdown and how to calculate them makes you a smarter trader.

Knowing your drawdown allows you to make better decisions and avoid large losses. Additionally, testing new strategies on a demo account before risking real money is a great way to learn without financial risk. You still have time to practice and better understand your drawdown.
