Liquidation in crypto trading occurs when a leveraged position is forcibly closed by an exchange or protocol because the trader’s collateral (margin) has fallen to the liquidation threshold — the point at which continued losses would exceed the deposited collateral. Liquidation protects the lender (exchange or protocol) from losses when a borrower’s position moves against them. For the trader, liquidation means losing all or most of the margin deposited to open the position. In volatile crypto markets, liquidations can cascade — one liquidation causes price to move, triggering more liquidations, causing a chain reaction known as a “liquidation cascade.”
How liquidation works: a trader opens a 10x leveraged long on BTC with $1,000 margin (controlling $10,000 exposure). Their liquidation price is approximately 10% below entry — if BTC falls 10%, their $1,000 margin is consumed and the position is closed. Key liquidation concepts: Margin ratio — the ratio of margin to position value; as losses mount, this falls toward the liquidation threshold; Maintenance margin — the minimum margin required to keep a position open; Partial liquidation — some exchanges reduce position size rather than closing entirely; Insurance fund — exchange reserves used to cover losses in extreme moves where liquidation doesn’t fully cover the debt. Tracking liquidation levels using tools like Coinglass helps traders understand where clusters of leveraged positions may force exits, identifying potential volatility zones.
Example: Coinglass shows $800M in long liquidations clustered at BTC $92,000. The market drops to $92,100, triggers those liquidations, causing a rapid $3,000 flash crash as forced selling overwhelms buyers momentarily.
