Leverage and Margin

Think about buying a house with a home loan. You put down $20,000 and the bank lends you $80,000 for a $100,000 home. If the house rises 10% to $110,000, your $20,000 stake becomes $30,000, a 50% gain. If it falls 20% to $80,000, your entire stake is gone. Leverage in trading works the same way, except the deposit is far smaller and the price moves happen in hours, not years.

What leverage really does

Leverage lets you control a position much larger than the money in your account. A leverage of 1:100 means every $1 of your money controls $100 in the market.

Here is the one sentence to remember from this lesson:

Leverage does not change how much the market moves. It changes how much that move costs or pays you.

A 0.5% move in EUR/USD is a 0.5% move whether you have $100 or $100,000 on the line. Leverage just decides which of those amounts it is.

What is margin?

Margin is the amount of your own money the broker sets aside to keep a leveraged trade open. It is a deposit, not a fee. You get it back when the trade closes, plus or minus your profit or loss.

Margin required = position value ÷ leverage

A few more terms you will see on every platform:

• Equity is your account balance plus or minus the profit or loss on open trades.
• Free margin is equity minus the margin already in use. It is what you have left to absorb losses or open new trades.
• Margin level is equity ÷ used margin × 100%.
• A margin call is a warning that your margin level has dropped too low (often at 100%).
• A stop out is when the broker automatically closes your trades because your margin level fell even further (often at 50%). Exact levels vary by broker.

Worked example: one trade, two endings

You have a $1,000 account. Your broker offers 1:200 leverage, which is common at some offshore brokers.

You buy 1 standard lot (100,000 units) of EUR/USD at 1.1000.

• Position value: €100,000 × 1.1000 = $110,000
• Margin required: $110,000 ÷ 200 = $550
• Pip value: $10 per pip
• Your effective leverage: $110,000 ÷ $1,000 = 110 times your account

Ending 1: the gain

EUR/USD rises 50 pips to 1.1050.

• 50 pips × $10 = +$500
• Your account grows to $1,500, a 50% gain from a 0.45% move in the euro.

This is the ending people show in advertisements.

Ending 2: the wipeout

EUR/USD falls instead.

Price	Pips against you	Loss	Equity	Margin level	What happens
1.1000	0	$0	$1,000	182%	Trade opened
1.0955	45	−$450	$550	100%	Margin call warning
1.0928	about 72	about −$725	about $275	50%	Broker closes your trade

A move of well under 1% in the euro took away almost three quarters of your account. Moves of that size happen regularly, sometimes within a single afternoon. And in a fast market, prices can jump past the stop-out level before your trade is closed. Some regions require brokers to offer negative balance protection; without it, you could end up owing the broker money.

The same idea, smaller size

Now look at the same 50-pip move with smaller positions on the same $1,000 account:

Position size	Pip value	50-pip move	Share of account
1 standard lot (100,000)	$10	$500	50%
1 mini lot (10,000)	$1	$50	5%
1 micro lot (1,000)	$0.10	$5	0.5%

Same market, same move, same leverage on offer. The only difference is how much of it you chose to use.

Why regulators cap leverage

Regulators have seen what high leverage does to retail traders. In the US, forex leverage is capped at 1:50 on major pairs. In the UK and EU, retail traders are capped at 1:30 on majors. Under a 1:30 cap, our $110,000 trade would need about $3,667 in margin, so the $1,000 account could not even open it. That is the point.

Why beginners keep leverage low

• Room to be wrong. Every trader has losing streaks. Low leverage means a streak hurts instead of ending your account.
• Time to think. With small positions, a sudden move is uncomfortable, not panic-inducing. Panic leads to bad decisions.
• Available is not required. Your broker may offer 1:500. You do not have to use it. What matters is how big your positions are compared to your account.

The best way to control leverage is to size every trade by how much you are willing to lose, usually 1% of your account or less. Do that, and your leverage stays low on its own. The Risk & Psychology course shows you exactly how.

Risk note: High leverage is the most common way beginners lose their accounts. If a broker pushes high leverage as a selling point, treat that as a warning sign, not a feature.

Key takeaways

• Leverage lets you control a large position with a small deposit; it magnifies gains and losses equally.
• Margin is a deposit set aside by your broker, not a fee.
• Margin calls and stop outs can close your trades automatically when losses pile up.
• A move of less than 1% can wipe out most of an over-leveraged account.
• Keep position sizes small and leverage low, whatever your broker offers.
