Why liquidation should sit twice as far as your stop

Your stop is the exit you chose. Liquidation is the exit the exchange chooses for you.

Every leveraged position has two exits. One you place deliberately at the level where your idea is proven wrong. The other is placed by the exchange at the point where your margin is exhausted. Most traders spend all their attention on the first and never calculate the second, which is precisely backwards — because only one of those two exits is optional.

How liquidation distance works

As a rough guide, the distance from your entry to liquidation is the inverse of your leverage. At 5x it sits around 20% away, at 10x around 10%, at 20x around 5%, and at 50x around 2%.

These are approximations. Real formulas differ by venue and include maintenance margin, fees and, in cross-margin mode, the rest of your balance. Always confirm the exact figure on the platform you are trading. But the shape of the relationship never changes: more leverage, less room.

The detail that catches people out

The practical consequence is that liquidation can occur without the visible price ever printing your liquidation level, and equally that a violent wick may not liquidate you when it appears to have done so. You cannot precisely predict either case, which is exactly why you build in margin for error rather than trying to calculate the edge.

The rule

If your stop sits 3% from entry, liquidation should be at least 6% away. If your stop is 5% away, you need 10%. When the ratio falls below two, ordinary volatility can remove the position before your stop is ever reached — and being liquidated means losing the entire margin allocated to that position, not the small amount you had defined as your risk.

A worked case

You want to buy at $60,000 with a stop at $58,200. That is a 3% stop. You are considering 20x leverage, which puts liquidation roughly 5% away, at about $57,000.

The ratio is 5 ÷ 3, or 1.67. Below two. The position is fragile: a 4% dip that recovers immediately would leave your stop untouched but could still liquidate you depending on mark price. Reduce to 10x and liquidation moves to roughly 10% away, giving a ratio of 3.3. Same trade, same stop, same risk in dollars — but now the exchange is unlikely to close it before your own plan does.

Leverage does not change your risk. It changes your survival room.

This is the part that confuses people. If you size positions properly, your risk in dollars is set by your stop distance, not by leverage. Whether you use 2x or 20x, a 3% stop on a correctly sized position loses the same amount of money.

What leverage actually changes is how much noise the position can absorb before the decision is taken away from you. Low leverage buys room. High leverage sells that room in exchange for using less margin — a trade almost nobody consciously agrees to when it is phrased that way.

Before every leveraged entry

1. Place the stop where your idea is invalidated, and measure that distance as a percentage.
2. Calculate liquidation distance for the leverage you intend to use.
3. Divide the second by the first. If the answer is under two, lower the leverage or widen the stop.
4. Check funding. On a multi-day hold it is a real cost, not a footnote.
5. Confirm the exchange's own liquidation figure before you submit.

The Preflight position size panel performs steps two and three automatically and warns you when the ratio breaks. It takes about fifteen seconds — considerably less time than recovering from a liquidation.
