Maintenance Margin Buffer

The maintenance margin buffer is the amount of collateral held above the minimum required level, providing a cushion against sudden market moves. This buffer is the primary defense against being liquidated during periods of high volatility.

A larger buffer allows a trader to withstand more significant adverse price movements without triggering a margin call. However, maintaining a large buffer also means that more capital is locked up, which can reduce the overall capital efficiency of the strategy.

Traders must carefully manage this buffer by balancing their desire for high leverage with the need for safety. It is a dynamic variable that changes as the market price of the collateral and the position value fluctuate.

Experienced traders often set their own internal maintenance margin requirements that are higher than the protocol's minimum to ensure they have enough time to react to market changes. This is a critical aspect of personal risk management that can be the difference between surviving a market cycle and being liquidated.
