If you understand the meaning of leverage accurately, your trading game changes dramatically. I recently went over this, and I found that beginners really miss a lot. Let’s start with what leverage actually is.

Leverage is, simply put, a way of trading by borrowing money from a broker. It’s like using a lever to lift something heavy with little force—meaning you can make large-scale trades with a small amount of capital. For example, if you have 1,000,000 won and use 10x leverage, you can trade in a 10,000,000 won position.

Once you know the meaning of leverage, its effect becomes easier to understand. Think about what happens when the price rises by 1%. Without leverage, investing 1,000,000 won gives you a profit of 10,000 won. But with 10x leverage, investing 10,000,000 won results in a profit of 100,000 won. Conversely, if the price drops by 1%, a 10,000 won loss becomes amplified to a 100,000 won loss. This is the key point.

For a more extreme example, with 1,000,000 won and 20x leverage, if the price increases by 5%, you can earn the entire 1,000,000 won principal. But if it falls by 5%, you lose all of your capital. This is the double-edged sword of leverage trading.

The concept of margin is also important. Margin is the amount of money you must deposit as collateral in order to keep your position. If you can’t meet the margin requirements, a margin call will occur—meaning you’ll need to deposit additional funds, or your position may be forcibly liquidated. The leverage ratio refers to the ratio of tradable funds relative to your margin. So if it’s 10:1, it means you trade a 10,000,000 won position using 1,000,000 won of margin.

If you truly understand the meaning of leverage, you should now look at its pros and cons. The advantage is that potential returns are higher—you can trade large positions with little capital, and you can also trade expensive assets more easily. Portfolio diversification also becomes easier, because with the same capital you can open more positions.

However, the disadvantages are also significant. The biggest problem is that losses are magnified as well. If the price drops by 10% and you use 10x leverage, you take a 100% loss and can wipe out your entire capital. There are risks like margin call risk, risk caused by market volatility, and the burden of borrowing costs, along with considerable psychological stress. Even small price movements can lead to big losses, so it’s easy to get swept up emotionally.

You should think about whether leverage trading is right for you. You need to check whether you’re prepared to accept losses larger than your initial investment, whether you can manage your emotions well, and whether you understand the market sufficiently. It can be a good tool for experienced traders, but it can be risky for beginners.

Risk management is crucial. You must set stop-loss orders and adjust your position size according to your capital. You should spread your portfolio across multiple assets and continuously monitor market conditions. Use trailing stops to protect your profits, and avoid excessive leverage. Keeping a trading journal to analyze past trades also helps.

Leverage can be used across various products such as the forex market, CFDs, futures, and options. In the forex market, because exchange-rate fluctuations are relatively small, many traders use high leverage of 100:1 or more. With CFDs, you can profit from price movements without directly owning the underlying asset. Futures and options are also commonly used for leveraged trading.

In conclusion, if you know the meaning of leverage correctly and manage risk properly, you can maximize your profits. However, the risks are substantial too, so you should approach it carefully. The most important thing is to decide based on your risk tolerance, experience, and capital situation.
