Leverage, margin and liquidation
Leverage lets a small deposit control a large position. It multiplies losses just as fast as gains.
What it is
Leverage lets you open a position larger than your deposit. At 10× a 1% price move changes your equity by 10%. Margin is the deposit that backs the position. If price moves against you far enough, the exchange closes the position: liquidation.
Leverage does not change what a good trade is. It changes how much room you have to be wrong. The professional approach is to size by risk (distance to the stop) and treat leverage only as the margin tool that lets you hold that size.
How to use it
- Choose position size from your stop distance (see position sizing).
- Use only enough leverage so that the liquidation price is far beyond your stop.
- Prefer isolated margin so one position cannot drain the whole account.
- Never add margin to a losing position to avoid liquidation.
Common mistakes
- Using 50–100× leverage for a tiny edge.
- Having the stop beyond the liquidation price, so the exchange stops you first.
- Averaging down into a leveraged loser.
