What Is Leverage in Trading?
Leverage lets you control a position larger than your cash by borrowing from your broker. Here is how it works, a clear example, and why it magnifies losses as much as gains. Educational, not financial advice.
Leverage lets you control a position larger than your own cash by borrowing the rest from your broker. Expressed as a ratio, 10:1 leverage means $1,000 of your money controls a $10,000 position. It magnifies both gains and losses — the same price move makes, or costs, ten times as much. Educational, not financial advice.
How it works
With 10:1 leverage and $1,000, you control $10,000. A 1% move in your favour is $100 — a 10% gain on your cash. But a 1% move against you is also $100 — a 10% loss. Leverage does not change the market's move; it changes how big that move is relative to your money.
The double-edged risk
- Losses are magnified exactly as much as gains.
- A move against a highly leveraged position can trigger a margin call — the broker closing your position, or asking for more funds, to cover the loss.
- Higher leverage means a smaller adverse move can wipe out your cash.

Leverage does not change good risk management
| Leverage | $100 risk on a trade |
|---|---|
| None | Still $100 |
| 10:1 | Still $100 — if you size to your risk |
The 1% rule and position sizing still apply: your risk per trade should be the same small fraction whether or not leverage is available. Leverage is a tool for capital efficiency, not a reason to risk more.
Takeaway
Leverage lets a small amount of cash control a larger position, magnifying gains and losses equally and adding margin-call risk. Treat it as capital efficiency, keep your risk per trade fixed and small, and respect that it cuts both ways.
