Margin Isolation

Margin isolation is a risk management mechanism where the collateral supporting a specific trade is restricted solely to that position, preventing losses from affecting the rest of the trader's account balance. In options trading and crypto derivatives, this prevents a single losing trade from triggering a cascade of liquidations across other healthy positions.

When a position is isolated, the exchange or protocol calculates the maintenance margin requirement only against the specific assets allocated to that trade. If the position price moves against the trader beyond the isolated margin threshold, only that specific collateral is liquidated.

This contrasts with cross-margin, where the entire account balance acts as collateral for all open positions. Margin isolation is crucial for high-leverage trading, as it provides a safety net that preserves the integrity of the remaining portfolio.

It requires active monitoring of individual position health. Traders often use this feature to experiment with high-risk strategies without jeopardizing their core capital.

It is a fundamental tool for controlling the scope of potential losses in volatile digital asset markets.
