What Is Liquidation Engine?
The liquidation engine is the automated system on derivatives exchanges that monitors all open leveraged positions and forcibly closes them when the trader's margin drops below the maintenance requirement. Its primary function is to prevent traders from accumulating losses beyond their deposited collateral, protecting the exchange and other traders from bad debt.
How Liquidation Engine Works
Modern liquidation engines use tiered liquidation (closing positions in chunks rather than all at once), auto-deleveraging (ADL, where profitable positions on the opposite side are automatically reduced), and insurance funds (pools of capital that absorb losses when liquidations can't be filled at the bankruptcy price). The liquidation price is calculated based on entry price, leverage, and maintenance margin.
Why It Matters for Traders
Understanding how liquidation engines work is essential for survival in leveraged crypto trading. Key insights: liquidation prices move when you add or remove margin, partial liquidations reduce position size to lower the maintenance requirement, and liquidation cascades occur when large liquidations move the market price enough to trigger additional liquidations in a feedback loop.
