The operational logic of leverage ratio and trading practices

Core Concepts of Leverage

The foreign exchange market is attractive to traders mainly because of its leverage mechanism. In simple terms, leverage refers to the method by which traders borrow funds from brokers to control larger positions with less of their own capital.

For example: you have $1,000 but want to trade a currency pair worth $100,000. You don’t need to pay the full amount upfront; instead, you deposit a portion of the funds as margin (usually called the initial margin), and the rest is provided by the broker. This borrowed amount helps you amplify your trading size, thereby increasing potential profits. However, note that while gains are magnified, losses are also proportionally increased.

Definition and Significance of Leverage Ratio

Leverage ratio is an indicator that reflects the proportion between trading capital and actual personal funds. It visually shows how many times your capital can be used for trading.

For example, a 1:100 leverage means: you invest 1 dollar and control a trading position of 100 dollars. A 1:200 leverage indicates that investing 1 dollar allows control of a 200-dollar position. The higher the leverage multiple, the lower the margin requirement.

Margin Requirements and Corresponding Leverage Multiples

Brokers set different margin requirements depending on the currency pair. The lower the margin ratio, the higher the available leverage multiple. Here are common scenarios:

• Margin requirement 1%, corresponding to leverage ratio 1:100
• Margin requirement 0.5%, corresponding to leverage ratio 1:200
• Margin requirement 2%, corresponding to leverage ratio 1:50

It’s important to note that brokers will adjust leverage ratios based on market volatility. When certain currency pairs experience extreme fluctuations, brokers often increase margin requirements to reduce risk exposure.

Practical Example of Leverage Trading

Suppose the current EUR/USD quote is 1.26837, and you plan to buy 1 standard lot (100,000 units of euros).

Without leverage: Total capital needed = 1.26837 × 100,000 = $126,837

With 1:200 leverage:

• Margin required = 126,837 × 0.5% = $634.19
• Remaining funds ($126,202.81) are provided by the broker

The key point is: regardless of leverage used, profit and loss are calculated based on the full position size.

If EUR/USD rises from 1.26837 to 1.26867 (a 30-pip increase):

• Profit = (1.26867 - 1.26837) × 100,000 = $300

Conversely, if it drops to 1.26707 (a 130-pip decrease):

• Loss = (1.26707 - 1.26837) × 100,000 = -$1,300

The same market movement, with only $634 margin invested, results in a $300 profit or a $1,300 loss. The profit/loss relative to the margin is far beyond 100%, which exemplifies the double-edged nature of leverage.

Risks and Management of Leverage Trading

Leverage is a double-edged sword. When the market moves in your favor, leverage amplifies gains; but when it moves against you, losses are also magnified. In extreme cases, you could lose your entire margin in a short period.

Therefore, in actual trading, leverage should be used cautiously:

• Beginners should start with lower multiples (1:50 or 1:100)
• Establish clear stop-loss strategies to control maximum loss per trade
• Regularly review and analyze trading to accumulate leverage experience
• Use demo accounts for risk-free practice until fully understanding leverage mechanisms

Understanding how leverage works and establishing a scientific risk management system are the foundations for long-term stable trading.
