Leverage basics: How advanced traders use leverage to diversify risk

Most traders associate leverage with increased risk, but is that the whole story? Learn the difference between account leverage and real leverage, and how leverage can help diversify trading risk instead of simply increasing it.

In CFD retail trading, leverage is frequently marketed as a tool to open bigger trade sizes and amplify short-term returns. Brokers often highlight ratios like 1:100 or 1:500 to show how small deposits can control larger trade volume.

However, using leverage solely to increase trade volume on a single instrument raises the risk of trading failure.

When managed correctly, professional traders do not view leverage as a mechanism for taking oversized risks on a single asset. Instead, they use leverage as a capital efficiency tool to diversify their trading portfolio/position. This is because leverage reduces the amount of margin locked in any single trade, freeing up more capital to be distributed across multiple instruments.

Account leverage vs real leverage

To utilize leverage properly and diversify your trading risk, you must understand that "leverage" operates on two distinct levels: account leverage versus real leverage.

Account leverage (leverage settings)

Account leverage is a leverage cap set in your trading account, often shown as a ratio like 1:100 or 1:500, and dictates the required margin calculation to open a trade.

For example, you want to open a 1 lot USDCHF trade with an account leverage of 1:100; in this case, following the margin requirement formula:

Trading Volume / Leverage = Margin

Example:

• Account’s equity 10,000 USD
• Account’s leverage 1:100
• Trading volume 100,000 USD (1 lot USDCHF)

100,000 USD / 100 = 1,000 USD margin

Therefore, if you have 10,000 USD in your account, you can open a trade up to 10 lots USDCHF.

Real leverage (actual leverage used in a trade)

Real leverage represents your actual risk or market exposure. It is the actual leverage you utilize when opening trades. 

It is calculated based on the trade volume relative to the account’s equity. 

Trading volume / Equity = Real leverage

Example:

• Account’s equity 10,000 USD 
• Account’s leverage 1:100
• Trading volume 100,000 USD (1 lot USDCHF)

100,000 USD volume / 10,000 USD equity = 10 In this case, real leverage for your 1 lot USDCHF trade is 1:10 (10,000 USD/100,000 USD)

Real leverage is your real risk

Account leverage defines the limit on how much trading volume you can open in comparison to the amount of funds in your account, but does not inherently create risk. Your risk comes from your executed trade volume.

The bigger your real (order size) leverage compared to your equity, the higher your trading risk. Using appropriate position sizing helps keep your market exposure aligned with your risk tolerance.

For example, imagine you have 1,000 USD in equity in your account and you open a 1 lot USDCHF trade (100,000 USD trading volume). This means you are controlling 100,000 USD in trade volume with just 1% of actual funds, effectively making your real leverage 1:100 (1,000 USD equity/100,000 USD trading volume).

Now, if the USDCHF price moves by approximately 1% in the opposite direction of your trade (USD to CHF exchange rate changes by 1%), the loss would be about 1,000 USD. Therefore, with just 1% price movement, your account could be completely wiped out.

But if you trade a smaller volume, like 0.1 lot USDCHF (10,000 USD trading volume), the same 1% move would only cause a 100 USD loss. 

Use leverage to diversify trading risk

Using higher (real) leverage in your trading activity does increase your trading risk. However, understanding the relationship between leverage and margin and using it correctly, can make leverage a valuable tool for diversifying trading risk and reducing the overall risk of your trading activity.

Trading portfolio allocation

Instead of deploying your entire account leverage capacity into a single high-risk trade position, you can diversify your trading risk across several different positions. This can help reduce the impact of an unfavorable price movement in one specific instrument.

Example:

• Account Equity: 1,000 USD
• Account Leverage: 1:100

Portfolio allocation of 100,000 USD trading volume:

• 0.10 lot USDCHF
• 0.10 lot USDJPY
• 0.10 lot USDCAD
• 0.14 lot AUDUSD
• 0.08 lot EURUSD
• 0.07 lot GBPUSD
• 0.17 lot NZDUSD
• 0.08 lot EURGBP
• 0.08 lot EURAUD
• 0.08 lot EURCHF

Disclaimer: the position sizes shown above are approximate examples for educational purposes only. Actual margin requirements and position values may differ due to market price movements, currency conversion rates, instrument specifications, and account currency calculations.

By spreading exposure across multiple instruments, a trader reduces reliance on the outcome of a single position. For example, if one trade moves negatively, the potential loss may be partially or even fully offset by gains from other positions, depending on the relationship between the instruments and overall market conditions.

The misconception of portfolio allocation

The concept behind diversification is based on managing concentration risk. Financial markets are interconnected, and different currencies' value may strengthen or weaken relative to each other based on economic conditions, interest rates, geopolitical events, and market sentiment. Because currency pairs represent the relative value between two currencies, movements in one pair may create opportunities or risks in another pair.

However, diversification should not be considered a guaranteed trading solution or a "holy grail". Opening multiple positions does not automatically reduce risk if those positions are highly correlated or exposed to the same underlying factor. Effective risk management depends on understanding the relationship between instruments as well. 

For example, opening “buy” positions on:

• USDCHF
• USDJPY
• USDCAD

This may appear to be diversification because it involves three different currency pairs. However, all three positions buy USD as the base currency, creating exposure only to the US dollar.

If the USD weakens significantly, all three positions may move negatively at the same time. Therefore, although the trader has multiple positions, the overall risk is still concentrated on the same currency.

True diversification requires looking beyond the number of trades and considering the underlying drivers of each position. A well-diversified portfolio should aim to balance different types of exposure rather than simply increasing the number of open trades across multiple instruments.

How to build a well-diversified trading portfolio

Building a well-diversified trading portfolio is not simply about opening multiple positions across different instruments. The objective of diversification is to create a balance of different types of market exposure, reducing the risk of being overly dependent on a single currency alone.

A diversified portfolio considers what drives each instrument’s price movement, how different positions interact with each other, and whether the overall exposure is concentrated in one direction.

Understand the source of each market exposure

Before adding a new position, traders should consider what factors influence the instrument’s price.

Different markets react to different economic and market conditions:

• Currencies (Forex): Primarily influenced by interest rates, central bank policies, economic growth, inflation data, and geopolitical events.
• Metals and energies: Often influenced by inflation expectations, interest rates, US dollar movements, and demand for safe-haven assets.
• Stocks and indices: Influenced by company performance, economic conditions, market sentiment, and investor expectations.

A portfolio becomes more balanced when positions are influenced by different drivers rather than relying on the same market factors.

Consider correlation between instruments

Correlation refers to how similarly two or more instruments tend to move in response to market conditions.

Highly correlated positions may increase risk concentration even when they appear to be different trades.

For example:

• Several positions that benefit from USD strength may carry similar exposure. For example, buying USD and USOIL at the same time.
• Multiple positions in risk-sensitive assets may react similarly during periods of market uncertainty.

Before adding a new trade, traders should ask:

"Does this position provide a new source of exposure, or does it increase my existing exposure?" This type of assessment should form part of a broader risk management framework.

A position that behaves similarly to existing trades may add more risk rather than meaningful portfolio diversification.

Balance different market conditions

A well-diversified portfolio should consider how positions may perform under different market environments.

For example:

• Some instruments may benefit during periods of economic growth.
• Some may perform better during periods of uncertainty or increased demand for defensive assets.
• Some may react strongly to changes in interest rate expectations.

The purpose is not to predict every market scenario, but to avoid having the entire portfolio dependent on one specific outcome.

Manage position sizes across the portfolio

Diversification is only effective when combined with appropriate position sizing.

A portfolio with ten positions can still carry significant risk if some positions are too large compared to the others. A balanced portfolio focuses not only on the number of trades but also on the risk level attached to each position.

Fortunately, Exness Terminal has a Risk calculator to help traders calculate an appropriate position size before opening a trade. The calculation is based on the amount of risk the trader is comfortable with and the stop loss level defined by their trading strategy.

The Risk Calculator feature in Exness Terminal

Managing risk effectively starts before you enter a trade. That is why Exness Terminal provides the Risk calculator—a simple yet powerful tool designed to help traders determine a more suitable position size based on their risk preference and planned stop loss level.

The Exness Terminal Risk Calculator supports leverage risk management by helping traders calculate an appropriate position size before entering a trade, making portfolio diversification in trading easier to manage.

Instead of manually calculating trade volume, traders can simply enter their desired risk amount and stop loss distance from the entry price. The tool will automatically calculate the appropriate order size, helping traders align their position size with their trading strategy and risk management approach.

Once the calculation is complete, traders can review the suggested position size and execute the trade with just a few clicks.

Using the Risk calculator, traders spend less time on complex calculations and more time focusing on making informed trading decisions.

Regularly review and adjust portfolio exposure

Market conditions change over time. A portfolio that is diversified today may become concentrated later due to changes in market conditions.

Regular portfolio reviews can help traders identify:

• Increasing exposure to a specific currency or market
• Positions that have become highly correlated
• Whether the overall risk level remains appropriate

Final thoughts

Leverage is neither good nor bad. Like any tool, its impact depends on how it is used. While excessive leverage applied to a single position can significantly increase the risk of large losses, a thoughtful approach to leverage can provide traders with greater flexibility to manage their capital and diversify their market exposure.

The key difference between inexperienced and disciplined traders is not the amount of leverage available, but how they manage their actual exposure. Understanding the difference between account leverage and real leverage allows traders to make better decisions about position sizing, risk management, and portfolio allocation.

A well-constructed trading portfolio is not built by simply opening more trades. True diversification comes from understanding what drives each market, managing correlations between instruments, and balancing different types of exposure. The goal is not to eliminate risk—which is impossible in trading—but to manage it in a more structured and intentional way.

Ultimately, successful risk management begins before entering a trade. By combining appropriate position sizing, diversification principles, and tools such as the Risk calculator in Exness Terminal, traders can make more informed decisions and build a trading approach that focuses not only on potential opportunities but also on protecting their capital.

Remember: Leverage does not determine your risk—your decisions determine your risk.
