Leverage Explained: How Small Price Moves Can Lead to Big Losses

Leverage allows you to open a larger market position with a smaller amount of money. It can give traders more market exposure, but it also means that even a small price movement can have a bigger impact on their account.

For beginners, understanding how leverage works is essential before opening a CFD position.

How Does Leverage Work?

Let's look at a simple example.

Suppose you have $100 in your trading account and use 10:1 leverage. This allows you to open a position worth $1,000.

Now, imagine the market moves:

1. If the price rises by 1%, your position gains $10.
2. If the price falls by 1%, your position loses $10.

That's a 10% gain or loss compared with your initial $100, before trading costs.

Without leverage, a $100 position moving by 1% would only result in a $1 gain or loss.

This is why leverage can make both profits and losses larger relative to the money you put up.

Why Can High Leverage Be Risky?

The biggest mistake beginners make is assuming that higher leverage means a better chance of making money.

It doesn't.

Higher leverage allows you to control a larger position, but it also means your account balance can be affected much faster when the market moves against you.

For example, with 20:1 leverage, a $100 account could control a $2,000 position. A 2% price move against that position would result in a $40 loss, equal to 40% of your initial funds, before costs.

If the market keeps moving in the wrong direction, losses can build quickly. Depending on your account terms and margin requirements, your position may also be closed automatically.

3 Things Beginners Should Remember

1. Don't use the maximum leverage available.

Just because your account allows higher leverage doesn't mean you need to use it. Start with a position size you can afford to manage.

2. Know how much you could lose.

Before opening a position, work out how much a price move against you could cost. Never focus only on the potential profit.

3. Use stop-loss orders carefully.

A stop-loss can help limit losses by closing a position at a chosen price. However, execution may differ in fast-moving or gapping markets, so it cannot guarantee an exact exit price.

The Bottom Line

Leverage is a tool, not a shortcut to bigger profits. It can increase your market exposure, but it also increases the impact of price movements on your account.

For new traders, the goal should not be to use as much leverage as possible. It's to understand the risks, control position sizes and avoid putting too much capital at risk on a single trade.
