Maintenance Margin

Maintenance Margin is the minimum account balance that must be held at all times to keep an existing leveraged position open. Unlike initial margin, which is paid at the start, maintenance margin is a continuous requirement monitored by the exchange's risk engine.

If the equity in a trader's account drops below this threshold due to adverse price movements, the position becomes under-collateralized. This triggers a margin call, requiring the trader to deposit more funds immediately to restore the balance.

Failure to meet this requirement leads to the automatic liquidation of the position by the exchange to prevent further losses. In crypto markets, this process is often handled by automated smart contracts that execute liquidations in real-time.

Maintaining this level is critical for preventing negative account balances that could threaten the solvency of the trading platform. It ensures that the protocol remains protected even during sudden market downturns.
