What Is Liquidation in Crypto, and How Do You Avoid It?

Liquidation is when an exchange automatically closes your leveraged position because your margin can no longer cover its losses. It's the built-in downside of leverage: the more you use, the closer it sits.

Why liquidation happens

When you trade on margin, the exchange requires you to keep a minimum amount of equity behind the position — the maintenance margin. As the trade moves against you and your losses approach your margin, you hit the liquidation price, and the position is force-closed to stop your balance going negative. Higher leverage puts the liquidation price closer to your entry, so a smaller move triggers it.

Mark price, not last price

Liquidations are decided against the mark price — an averaged "fair" price — rather than the last trade on one exchange. This is deliberate: it stops a brief, manipulated wick on a single venue from liquidating positions that the broader market never actually moved against. Always read your liquidation price from the mark price, not the ticker.

What it costs

• Isolated margin — you lose the margin assigned to that position.
• Cross margin — the liquidation can reach your whole balance.
• A liquidation fee usually applies on top.

Exchanges also run insurance funds (and, in extreme cases, auto-deleveraging) to absorb liquidations that can't be filled cleanly — but from your side, the outcome is simply that the position is gone.

How to avoid liquidation

• Use less leverage. This is the single biggest lever — it pushes the liquidation price far from your entry.
• Set a stop-loss before the liquidation price. Exit on your terms, at a smaller, chosen loss.
• Add margin to a position under pressure (or use isolated mode to cap the damage).
• Size by risk. Decide the loss you'll accept first, then back into position size and leverage.

Liquidation isn't bad luck so much as a math certainty at high leverage. Respect the liquidation price and it rarely surprises you. Check where yours sits:
