Maintenance Margin Invariant

Parameter

The maintenance margin invariant is a critical risk parameter representing a constant or fixed ratio of collateral to the value of a leveraged position that must be sustained to avoid liquidation. This invariant dictates the minimum equity required in a trading account relative to the open position’s notional value. It serves as a non-negotiable threshold, ensuring that sufficient capital remains to cover potential losses. Deviations below this ratio trigger automated risk mitigation.
