Used Margin

Categories: Brokerages,

Amount of margin (typically money deposited in your brokerage account) that is set aside to keep trade positions open. The used margin acts as collateral, or a "good faith deposit" for the opened position, and is essentially locked away until that position is closed. Once trades are opened, the required used margin is deducted from your usable margin until the trade is closed. Also called maintenance margin or required margin.
