Liquidation in Perpetual Futures: Starter Guide

Liquidation is the forced closing of a leveraged position when its collateral can no longer cover potential losses. It is the single most important risk to understand before trading perpetual futures. On SorooshX you trade Hyperliquid perpetuals from your own wallet, with USDC as collateral, and liquidation is handled by Hyperliquid's rules. This starter guide explains why liquidation happens, how to see how close you are, and how to avoid it.

Why liquidation exists

With leverage you control a position larger than your margin. For example, 10x leverage lets 100 USDC of margin control a 1,000 USDC position. If the price moves against you, losses come out of that margin. Before losses can exceed the collateral, the position is closed so that the shortfall does not fall on other traders. That forced close is liquidation.

Key terms

• Initial margin: the USDC you lock to open the position. In the order ticket this is shown as Margin Required, equal to order value divided by leverage.
• Maintenance margin: the minimum collateral a position must keep. It is a fraction of the initial margin at the market's maximum leverage, set by Hyperliquid per market.
• Mark price: the price used for profit and loss and for liquidations. It is a smoothed blend of order-book and oracle prices, so a brief spike in the last traded price alone does not liquidate you.
• Liquidation price: the estimated mark price at which your position would be liquidated.

How liquidation works on Hyperliquid

When your account value (for cross positions) or your position's margin (for isolated positions) falls below the maintenance margin requirement, the position becomes eligible for liquidation. Hyperliquid first tries to close it with market orders in the order book. If the book cannot absorb it, a backstop mechanism takes over the position. In either case, you lose the margin backing the position, and the position is gone.

On SorooshX, the MMR gauge on the trading page shows your maintenance margin ratio, from Safe to Watch to Danger. At 100% the most-leveraged position is closed automatically.

Worked example

Illustrative example only. Round numbers, ignoring fees, funding and the exact maintenance margin.

You open a 10x long on BTC at 100,000 USDC with 1,000 USDC of isolated margin, a position worth 10,000 USDC (0.1 BTC).

• A 1% drop to 99,000 costs 0.1 × 1,000 = 100 USDC, which is 10% of your margin.
• A 10% drop would cost the full 1,000 USDC. Because maintenance margin must stay in the account, liquidation happens before that point, somewhat less than a 10% move.
• At 2x leverage, the same 1,000 USDC margin would back a 2,000 USDC position, and it would take a far larger move to reach liquidation.

The lesson: the higher the leverage, the smaller the price move needed to liquidate you.

How to monitor and reduce liquidation risk in SorooshX

1. Check before you trade. The order confirmation shows Est. Liquidation for the trade you are about to place.
2. Watch open positions. The Positions tab below the chart shows each position's Liq. price, mark price and margin. Your Portfolio shows the same.
3. Use moderate leverage. Set it in Adjust Leverage. Higher leverage increases liquidation risk.
4. Set a stop loss. Use Take Profit / Stop Loss in the order ticket, or the TP / SL button on an open position, so you exit at a planned price well before liquidation.
5. Choose the right margin mode. Isolated limits the loss to one position's margin; cross shares your whole balance. See Isolated vs Cross Margin.

Common mistakes

• Maximum leverage by default. It leaves almost no room for normal volatility.
• No stop loss. A liquidation is a worse exit than a stop loss you chose yourself.
• Ignoring funding. Hourly funding payments slowly change your margin and therefore your liquidation price.
• Adding to a losing position without a plan. It can move your liquidation price closer, not further away.

FAQ

Will I lose more than my margin?

In isolated mode the loss on liquidation is limited to that position's margin. In cross mode, liquidation can use your cross margin balance.

Why was I liquidated when the chart never touched my liquidation price?

Liquidation uses the mark price, not the last trade on your chart. Funding and fees also move the liquidation price over time.

Can SorooshX stop a liquidation?

No. Liquidation is enforced by Hyperliquid's protocol rules. Your own risk controls are the only protection.

Where can I practise these ideas?

The lessons in SorooshX School cover leverage and risk step by step.

Risk reminder: leveraged trading can lose your entire margin quickly; only trade amounts you can afford to lose.
