Can Perpetual Contracts Be Liquidated? How to Calculate Liquidation Price

·

Yes!

Perpetual contracts can indeed be liquidated, although their unique design makes them less susceptible to malicious "price manipulation" compared to delivery contracts. Here's what you need to know:

How Perpetual Contracts Minimize Liquidation Risks

  1. Auto-Deleveraging: Reduces counterparty positions to lower market risk.
  2. Price Mechanism: Designed to resist forced liquidations (no "price spikes" or "split losses").
  3. No Expiry: Unlike delivery contracts, perpetuals avoid repeated rollover costs and missed opportunities.

    P&L = Size × (Exit - Entry)
  2. Quanto (COIN-M)
    Value = Size × Price × Conversion Rate
    P&L = Size × (Exit - Entry) × Conversion Rate
  3. Inverse (BTC/USD)
    Value = Size ÷ Price
    P&L = Size × (1/Entry - 1/Exit)
