Leverage and margin are two of the most important, and most misunderstood, ideas in trading. Used well, leverage is a tool. Used carelessly, it’s how accounts get wiped out. Here’s how they really work.
What leverage is
Leverage lets you control a larger position with a smaller deposit. Expressed as a ratio like 1:100, it means the controlled position can be one hundred times the deposited margin. Crucially, it magnifies both gains and losses, so a small move can have a much larger effect on your account.
What margin is
Margin is the deposit required to open and hold a leveraged position, it’s collateral, not a fee, and it’s returned when you close the trade. The higher the leverage, the less margin a position needs.
The risk to understand
Because leverage magnifies losses, a position that’s too large for your account can lose money fast. If losses erode your margin, you may get a margin call, and positions can be closed automatically at the stop-out level. This is why position sizing matters so much.
Using leverage responsibly
- Start with modest position sizes while you learn.
- Always use a stop loss, so a leveraged move can’t run away from you.
- Think in terms of controlled position risk, not the maximum size you’re allowed.
- Understand that higher leverage is not ‘more buying power’, it’s more risk.
- Leverage controls a larger position with a smaller deposit
- It magnifies gains and losses equally
- Margin is the collateral to hold a position, not a fee
- Use leverage with small sizes and a stop loss, always
