What liquidation actually means

The exchange closes your position because your margin can no longer cover the loss. It is not a warning — it is the end of that trade.

When you trade with leverage you are borrowing. The exchange lends you buying power and holds your margin as collateral. Liquidation is what happens when the loss on the position grows large enough to threaten that collateral: the exchange closes the position for you, and the margin allocated to it is gone.

Why it triggers on mark price

Liquidation does not use the last traded price. It uses a mark price — a smoothed reference built from spot markets across several exchanges. The reason is protective: without it, a single manipulated wick on one venue could liquidate everybody.

The consequence is that the number on your screen is not the number your position is judged against. Liquidation can occur without the visible price printing your liquidation level, and a violent wick may not liquidate you even when it looks like it should.

How far away is it?

As a rough guide, distance to liquidation is the inverse of leverage: about 10% at 10×, 5% at 20×, 2% at 50×. Real formulas include maintenance margin and fees, so always confirm the exact figure on your exchange.

Isolated versus cross margin

Isolated confines the risk to the margin assigned to that position. If it liquidates, you lose that margin and nothing else.

Cross uses your whole balance as collateral. It liquidates far less often — and when it does, considerably more is at stake.

For anyone still learning, isolated is the safer choice. It caps the damage of a single mistake at a number you chose in advance.

How to avoid it

1. Use less leverage than the platform offers. The maximum is a marketing number, not a recommendation.
2. Always place a stop, and place it well inside the liquidation level.
3. Check the liquidation-to-stop ratio before entering — the position size calculator does this automatically and warns you.
4. Never add margin to keep a losing position alive without a written plan. That is how a defined loss becomes an undefined one.

What the exchange is actually doing

When you open a leveraged position, the venue lends you exposure and holds your margin as collateral. It monitors that collateral continuously against the position's loss. Liquidation is simply the moment the collateral can no longer cover the loss with the required buffer.

At that point the exchange closes the position at market to protect itself. You do not choose the price, you cannot negotiate, and the margin assigned to that position is gone — usually with a liquidation penalty applied on top.

It is worth stating plainly: this is not a punishment, and nobody is targeting you. It is the mechanical consequence of an arrangement you agreed to when you chose leverage.

Maintenance margin, and why liquidation comes early

Liquidation does not wait until your collateral reaches zero. Each venue requires a maintenance margin — a minimum percentage that must remain — and closes the position when equity falls to that level.

This means the real liquidation price is closer than the simple inverse-of-leverage estimate suggests. Maintenance requirements also rise with position size on most venues: a large position at 10× may face a stricter requirement than a small one at the same leverage. Always confirm the figure the exchange itself displays rather than relying on a rule of thumb.

Partial liquidation and the cascade

Larger venues often liquidate in stages, closing part of a position to restore the margin ratio rather than eliminating it entirely. This is better than full closure, and it is still a forced sale at a price you did not choose.

Auto-deleveraging, the risk nobody mentions

If a liquidation cannot be filled at a price that covers the loss, the venue's insurance fund absorbs the shortfall. If that fund is exhausted during an extreme event, some exchanges use auto-deleveraging: profitable traders on the opposite side have their positions closed to balance the book.

This means a correct, profitable position can be closed without your consent during a crisis. It is rare, it is disclosed in the terms nobody reads, and it is one more reason that extreme leverage carries risks beyond the obvious one.

Six habits that prevent it

1. Use isolated margin until you can explain precisely why a trade needs cross.
2. Keep liquidation at least twice your stop distance. The position size calculator checks this and warns you.
3. Treat the maximum leverage as a marketing number, not a recommendation. Most venues offer far more than anyone should use.
4. Watch funding on multi-day holds — it erodes margin continuously and moves liquidation closer over time.
5. Never add margin to keep a losing position alive without a written plan. That is how a defined loss becomes an undefined one.
6. Check the exchange's own liquidation figure before submitting, every time.

If it happens

Do not open a replacement position the same day. The impulse to win the money back immediately is the strongest it will ever be, and it is exactly the state the loss cooler exists for: it shows the arithmetic of recovery and starts a thirty-minute pause.

Then log the trade honestly, including the leverage and the reason. Liquidations cluster in journals around specific behaviours — a particular session, a particular market, a particular emotional state. Finding that pattern is the only useful thing a liquidation produces.

Common questions

Can I be liquidated if the price never touches my liquidation level?

Yes. Liquidation uses mark price, a smoothed index built from several spot markets, not the last traded price on your screen. It can differ from what you see, in both directions.

Do I lose everything if I am liquidated?

You lose the margin allocated to that position plus a penalty. In isolated mode that is a defined amount. In cross mode it can draw on the entire account balance.

Is it better to be stopped out or liquidated?

Always stopped out. A stop is a loss you defined, at a price you chose, sized so it does not matter. A liquidation is a loss the exchange defined, at a price set by a cascade, plus a penalty.
