Leverage in Forex: How It Works and Why It Cuts Both Ways

Leverage in forex lets you control a position much larger than the money you put up, by borrowing buying power from your broker. At 1:500 leverage, $1 of your own money supports $500 of market exposure. That can make small accounts workable, but it magnifies losses exactly as much as it magnifies gains.

How does leverage in forex work?

When you open a leveraged trade, your account does not pay the full value of the position. Instead, it sets aside a fraction called margin, and the broker covers the rest. The leverage ratio tells you the size of that fraction. At 1:100 you set aside 1% of the position's value, and at 1:500 you set aside 0.2%.

All three DMA Capitals account types offer leverage up to 1:500. It is a ceiling, not a target. You choose how much of it to use through your position size, and using less is usually wiser.

A worked example at 1:500

Suppose EUR/USD is at 1.1000 and you want to buy 0.10 lot, which is 10,000 euros, worth about $11,000. These are illustrative figures.

• Position value: about $11,000
• Margin needed at 1:500: $11,000 ÷ 500 = $22
• Margin needed at 1:50: $11,000 ÷ 50 = $220

With a $1,000 account you could, in principle, hold a position vastly larger than the account itself. The margin calculator shows the exact figure for any pair and size.

Why leverage cuts both ways

Leverage changes the size of the position you can hold. The profit and loss are driven by that position, not by your deposit. A mini lot on EUR/USD is worth $1 per pip, so a 30 pip move is $30 whichever leverage you use.

Now compare two accounts of $1,000 that both hold one standard lot, $10 per pip.

• A 20 pip move in your favour: +$200, a 20% gain
• A 20 pip move against you: −$200, a 20% loss
• A 100 pip move against you: −$1,000, the entire account

The same trade that looks exciting when it works can end the account within a normal day's movement. This is why the risk warning says leveraged trading can lose more than a beginner expects.

Leverage does not change how often you are right. It only changes how much being wrong costs.

Leverage versus effective leverage

The ratio on your account is only the maximum. What matters in practice is effective leverage: the total value of your open positions divided by your account balance.

For example, a $1,000 account holding $11,000 of EUR/USD has effective leverage of 11 to 1. That is far below the 1:500 ceiling, and far easier to survive a bad run with. Many experienced traders keep effective leverage in single digits. A very high effective leverage means a tiny price move can wipe out the account, and it brings the danger of a margin call.

How to use leverage sensibly

1. Decide the money you will risk, often 1% or less of the account.
2. Place a stop loss at a sensible distance, then size the position from it using the risk calculator.
3. Check the margin the trade needs, and make sure it is a small part of your balance.
4. Leave plenty of free margin, so that normal swings do not close your trade.

Notice that leverage is the last thing you think about. It is a tool that lets the position exist, not a reason to make it bigger. Our guide to lot size in forex works through the sizing step by step.

A quick note on high and low leverage

Some traders assume that choosing a lower ratio is the safe option and a higher one the risky option. In reality the ratio only sets the ceiling on position size. Two traders at 1:500 can run very different risk: one holds a 0.04 lot on a $1,000 account, the other holds a full standard lot. The first is risking a few dollars per pip, the second ten. The difference is the decision about size, not the setting on the account.

Lower ratios do have one practical benefit. They stop you opening a position that is too large by accident, because the margin needed rises and the platform refuses the order. If you find yourself clicking quickly, that built-in limit can act as a brake. Whichever ratio you hold, the habit that protects you is the same: choose the money at risk first, then the stop, then the size.

What to do next

Try different position sizes on a demo account and watch how the margin used and the profit and loss figures change. Pay attention to how little price movement it takes to move the account when the position is large. You will find more answers in our FAQs.
