Liquidation is what happens when a leveraged position no longer has enough collateral to satisfy the platform's risk requirements. The position is reduced or closed so losses do not keep growing unchecked.

If you trade perpetual futures, liquidation is not an edge case. It is part of the product's core risk engine. You should know where your liquidation price is, what price source can trigger it, and how much collateral is at risk before you enter any position.

## Liquidation in One Paragraph

When you trade with leverage, you post margin to support a larger position. As the market moves, your unrealized PnL changes your equity. If your equity falls below the required **maintenance margin**, the platform can liquidate the position. Depending on venue rules and position size, liquidation may reduce part of the position first or close it entirely.

<Callout variant="key">
The goal of the liquidation engine is to keep the system solvent. The cost to the trader is that liquidation is a *forced* exit — often at a bad time, sometimes with less collateral returned than expected, and usually with a liquidation fee on top.
</Callout>

## Initial Margin vs. Maintenance Margin

Two margin concepts matter, and they are not the same number:

<CompareTable
  caption="The two margin thresholds"
  columns={["", "Initial margin", "Maintenance margin"]}
  rows={[
    { label: "What it does", values: ["Collateral required to open", "Minimum to keep the position open"], emphasis: [0, 1] },
    { label: "When it applies", values: ["At entry only", "Continuously, on every mark price tick"], emphasis: [0, 1] },
    { label: "Typical size (10× position)", values: ["~10% of notional", "~0.5–1% of notional"], emphasis: [0, 1] },
    { label: "Falling below it…", values: ["Order is rejected", "Position is liquidated"], emphasis: [1] }
  ]}
/>

Maintenance margin is usually lower than initial margin, but it is not zero. That is why a 10× position is not safely liquidated only after an exact 10% move against you. Fees, funding, maintenance margin, and mark-price movement can all bring liquidation closer than the simple headline leverage suggests.

## A Simple Example

You have $1,000 and open a 10× long ETH perp at $3,000. Position notional is $10,000.

<ScenarioCompare
  caption="The same trade, two market paths"
  scenarios={[
    {
      label: "Cushion intact · ETH → $2,900",
      headline: "−$333",
      tone: "neutral",
      body: "ETH dropped 3.3%. The position is down about $333 before fees and funding. You still have meaningful margin left — the trade is not in danger.",
      metrics: [
        { k: "Mark price", v: "$2,900" },
        { k: "Unrealized PnL", v: "−$333" },
        { k: "Remaining margin", v: "~$667" },
        { k: "Liquidation distance", v: "~6% away" }
      ],
      spark: [40, 38, 38, 36, 34, 34, 32, 30, 30, 28, 28]
    },
    {
      label: "Cushion thin · ETH → $2,800",
      headline: "−$667",
      tone: "short",
      body: "ETH dropped 6.7%. The position is down ~$667. Your cushion is thin — fees, funding, and a few more bad ticks against you could trip maintenance.",
      metrics: [
        { k: "Mark price", v: "$2,800" },
        { k: "Unrealized PnL", v: "−$667" },
        { k: "Remaining margin", v: "~$333" },
        { k: "Liquidation distance", v: "~3% away" }
      ],
      spark: [40, 38, 36, 32, 28, 24, 22, 20, 18, 16, 14]
    }
  ]}
/>

If ETH keeps falling, the platform will not wait until every dollar of margin is gone. Once equity approaches the maintenance margin threshold, the position becomes liquidatable. Use the stress test below to see where that line sits:

<LiquidationMeter side="long" entry={3000} current={2900} liquidation={2725} symbol="ETH" />

The exact liquidation price depends on venue parameters, mark price, fees, funding, position size, and margin mode. Treat liquidation price as a *live estimate* tied to risk parameters — not a decorative number on the order ticket.

## Mark Price vs. Last Price

Liquidations are generally triggered by a **mark price** or fair reference price, not simply the last traded price.

<Callout variant="warn" title="Why this matters">
The last traded price is the most recent execution on a venue. It can be noisy, especially in thin markets. **Mark price** is designed to represent fair value using oracle / reference pricing — and, in some systems, order-book conditions. This reduces the chance that a single odd trade or temporary wick unfairly liquidates users. *The chart price you are watching may not be the exact trigger source.*
</Callout>

Always check the platform's displayed liquidation price and mark-price methodology. The two prices usually move together, but in a sharp move or a flash wick, the gap can be the difference between getting liquidated and not.

## Partial Liquidation vs. Full Liquidation

Liquidation does not always mean the entire position disappears immediately. Most modern venues — Liquid included — try to close *just enough* to restore margin first.

<ScenarioCompare
  caption="Two ways the same liquidation can resolve"
  scenarios={[
    {
      label: "Partial liquidation",
      headline: "Reduced",
      tone: "neutral",
      body: "The system closes part of the position to restore margin requirements. You keep a smaller position and the remaining collateral, minus liquidation fees. Best-case path when liquidity is healthy.",
      metrics: [
        { k: "Position after", v: "Smaller" },
        { k: "Margin restored", v: "Yes" },
        { k: "Collateral kept", v: "Partial" },
        { k: "Fee impact", v: "Lower" }
      ]
    },
    {
      label: "Full liquidation",
      headline: "Closed",
      tone: "short",
      body: "Market is moving too quickly or liquidity is too thin to safely reduce. The whole position is closed. Backstop systems may engage if the close itself can't be filled cleanly.",
      metrics: [
        { k: "Position after", v: "Zero" },
        { k: "Margin restored", v: "—" },
        { k: "Collateral kept", v: "Whatever's left" },
        { k: "Fee impact", v: "Higher" }
      ]
    }
  ]}
/>

## Backstop Liquidation

If a normal market liquidation cannot close the position safely, a venue may use a **backstop liquidation** mechanism — the position and its associated collateral are transferred to a designated liquidator, protocol backstop, or insurance vault.

<Callout variant="danger" title="The cost of the last-resort path">
Backstop liquidation is a failsafe for fast markets and thin liquidity. It also means some or all of your maintenance margin may not be returned — the backstop needs a buffer to absorb execution and market risk. **Do not treat liquidation as a clean, fee-free stop loss.** It is a last-resort risk process and the worst path to exit a trade.
</Callout>

## What Determines Your Liquidation Price

Liquidation price is not a single static number on your order ticket — it is the output of six live inputs:

<CompareTable
  caption="The inputs your risk engine watches"
  columns={["Input", "What it does", "How to control it"]}
  rows={[
    { label: "Leverage", values: ["Higher leverage = less room", "Pick lower leverage at entry"], emphasis: [0] },
    { label: "Position size", values: ["Larger notional = larger PnL swings", "Size down on volatile assets"], emphasis: [0] },
    { label: "Maintenance margin %", values: ["Higher requirement = closer liquidation", "Read the asset's risk page"], emphasis: [0] },
    { label: "Margin mode", values: ["Cross pools, isolated walls", "Match mode to your trade thesis"], emphasis: [0] },
    { label: "Fees & funding", values: ["Erode equity over time", "Plan for holding cost"], emphasis: [0] },
    { label: "Mark price", values: ["The actual trigger source", "Compare to chart price live"], emphasis: [0] }
  ]}
/>

## Cross Margin vs. Isolated Margin Liquidation

With [isolated margin](/learn/cross-margin-vs-isolated-margin), only the collateral assigned to one position is directly at risk. With cross margin, positions share an account-level collateral pool — better survival on any single trade, more contagion if one really blows up.

<MarginModeDiagram totalCollateral={10000} loss={2500} positions={[
  { label: "ETH long (the loser)", size: "$4,000" },
  { label: "BTC short", size: "$3,500" },
  { label: "SOL long", size: "$2,500" }
]} />

Cross margin lowers the chance of isolated-position liquidation. It does not lower *total* risk. It changes where the risk is pooled.

## How to Reduce Liquidation Risk

<StepFlow
  caption="Six ways to reduce liquidation risk"
  steps={[
    { title: "Use lower leverage", body: "The simplest, most reliable fix. Lower leverage gives normal volatility more room before maintenance margin trips." },
    { title: "Set a stop before liquidation", body: <>Your <a href="/learn/what-is-a-stop-loss">stop loss</a> is your chosen exit. Liquidation is the platform's forced exit. You want your stop to trigger <strong>first</strong>.</> },
    { title: "Monitor liquidation distance, not just PnL", body: "A position can look manageable in dollar terms while sitting too close to liquidation. Always check the price gap, not just the unrealized loss." },
    { title: "Account for funding", body: <>Funding payments can reduce margin over time, especially on large notional positions. See <a href="/learn/what-are-funding-rates">how funding rates work</a>.</> },
    { title: "Add collateral only with a plan", body: "Adding margin moves liquidation further away — but it also increases capital at risk if the thesis is wrong. Refusing to add is sometimes the better trade." },
    { title: "Avoid high leverage during events", body: "Earnings, token unlocks, CPI prints, central-bank decisions, and major protocol events can move markets faster than normal stop logic expects." }
  ]}
/>

## Liquidation Cascades

A **liquidation cascade** happens when forced closures push price further in the direction of the move, causing more liquidations at nearby levels — and so on.

For longs, liquidation means *selling into a falling market*. For shorts, liquidation means *buying into a rising market*, which can create or intensify a [short squeeze](/learn/what-is-a-short-squeeze). Crypto and perp markets can cascade quickly because leverage is high, trading is continuous, and liquidation engines operate automatically.

<Callout variant="warn" title="Why traders watch liquidation clusters">
Liquidation clusters become important liquidity zones. Price can accelerate sharply when a large cluster is triggered — and slow down when the cluster has been cleared. Many discretionary traders track open interest and funding alongside liquidation maps for exactly this reason.
