What Is Leverage?
Leverage is borrowing capital from your broker to control a position larger than your account balance. A leverage of 1:100 means for every $1 in your account, you can control $100 in the market. This amplifies both profits and losses by the same factor.
💡 Example
With $1,000 and 1:100 leverage, you can open a position worth $100,000 (1 standard lot). If EUR/USD moves 1% in your favor, you gain $1,000 — a 100% return on your account. If it moves 1% against you, you lose your entire $1,000.
Leverage Ratios Explained
| Leverage | Position per $1,000 | Move to Wipe Account |
|---|---|---|
| 1:10 | $10,000 | 10% adverse move |
| 1:30 | $30,000 | 3.3% adverse move |
| 1:100 | $100,000 | 1% adverse move |
| 1:500 | $500,000 | 0.2% adverse move |
Margin — The Other Side of Leverage
Margin is the amount of capital your broker requires as a deposit to open a leveraged position. With 1:100 leverage and a $100,000 position, you need $1,000 in margin.
Free margin is your account equity minus used margin — it determines how much you can still trade and absorb losses before a margin call.
Margin call: When your losses reduce your account equity to a threshold (typically 50–100% of used margin), your broker issues a margin call and may automatically close your positions to prevent further losses.
How Leverage Affects Volatility Risk
EUR/USD moves approximately 80–100 pips on an average day. With 1:100 leverage and a 1 standard lot position, each pip = $10. A 100-pip adverse move = $1,000 loss — your entire $1,000 account. This is why professional traders:
- Never use maximum leverage
- Risk only 1–2% of account per trade
- Always use stop-loss orders
- Keep free margin above 1,000% of used margin
Regulatory Leverage Caps — Why They Exist
ESMA (EU) and FCA (UK) capped retail trader leverage at 1:30 for major pairs in 2018, following research showing that the majority of retail traders lost money — with higher leverage correlating directly with larger losses. The US CFTC caps leverage at 1:50. These caps are genuinely protective for most traders.
The 1% Rule — How Professional Traders Use Leverage
Even with access to 1:500 leverage, most professional traders risk 1% or less of their account per trade. On a $10,000 account, that means a maximum loss of $100 per trade. Your position size is then calculated to ensure a stop-loss represents this 1% risk — regardless of what leverage is available.
This approach allows you to endure 20–30 consecutive losing trades before risking serious account damage — giving your strategy time to prove itself without being wiped out by normal drawdown periods.
My Recommendation
Use the minimum leverage necessary to achieve your profit targets given your account size and risk tolerance. If you're new to trading, I recommend starting with no more than 1:10 leverage until you have a proven track record across at least 100 trades on a demo account.
⚠ Risk Disclaimer
Leveraged trading involves significant risk. Losses can exceed your initial deposit. Never trade with money you cannot afford to lose.
