What is Leverage?
Leverage allows you to control a large trading position with a relatively small amount of your own capital. It is essentially borrowed money from your broker that multiplies both your potential profits and your potential losses.
Leverage is expressed as a ratio — for example, 1:100 means that for every $1 of your own money, you can control $100 in the market. This makes forex trading accessible to retail traders with smaller accounts, but it also dramatically increases risk.
Leverage is one of the most powerful — and most dangerous — tools in forex trading. Used wisely, it can significantly enhance returns. Used carelessly, it can erase your entire account in minutes.
How Leverage Works
When you open a leveraged trade, your broker temporarily lends you funds to control a larger position. You deposit a small amount (called margin) as collateral, and the broker covers the rest.
The formula:
- Position Size = Margin Deposited × Leverage Ratio
- Required Margin = Position Size ÷ Leverage Ratio
Common leverage ratios in forex:
| Leverage | Margin Required | Controls |
|---|---|---|
| 1:10 | 10% | $10,000 with $1,000 |
| 1:50 | 2% | $50,000 with $1,000 |
| 1:100 | 1% | $100,000 with $1,000 |
| 1:500 | 0.2% | $500,000 with $1,000 |
Leverage Examples
Example 1 — Leverage working in your favour:
- You have $1,000 in your account
- You use 1:100 leverage to open a $100,000 EUR/USD position
- EUR/USD rises 50 pips
- Profit = 50 pips × $10/pip = $500 profit on $1,000 (50% return!)
Example 2 — Leverage working against you:
- Same setup: $1,000 account, 1:100 leverage, $100,000 position
- EUR/USD falls 50 pips
- Loss = 50 pips × $10/pip = $500 loss on $1,000 (50% loss!)
Without leverage, a 50-pip move on $1,000 would have been just $5. Leverage multiplied both the gain and the loss by 100x.
Risks of Leverage
The dangers of leverage are well-documented:
- Amplified losses: A 1% move against a 1:100 leveraged position is a 100% loss of your margin.
- Margin calls: If losses reduce your account balance too low, your broker may close all your positions automatically.
- Emotional pressure: Watching large paper losses (even on small accounts) induces panic and poor decision-making.
- Over-trading: Easy access to big positions tempts traders to risk too much per trade.
Effective leverage management:
- Use a leverage of 1:10 to 1:30 as an effective ratio (position size vs account balance) regardless of what your broker offers.
- Never use all available leverage just because you can.
- Calculate effective leverage: Total Position Value ÷ Account Equity = Effective Leverage
Leverage and Margin
Leverage and margin are two sides of the same coin:
- Leverage determines how large a position you can control.
- Margin is the deposit required by your broker to open and maintain that position.
Higher leverage = lower margin requirement. Lower leverage = higher margin requirement.
A 1:100 leverage on a $100,000 position requires $1,000 margin (1%). A 1:10 leverage on the same position requires $10,000 margin (10%).
Understanding this relationship is fundamental to managing your account's free margin and avoiding liquidation.
