Margin
In trading, margin is cash, securities, or other collateral required to finance or support a leveraged position.
Margin and leveraged-trading terms for collateral, broker credit, margin calls, securities borrowing, and forced-liquidation risk.
Margin and leveraged trading uses borrowed funds, collateral, or performance bonds to support market exposure. Leverage can magnify gains and losses, while financing cost, changing requirements, and liquidation rights can determine whether a position remains open.
Use Margin for the broad distinction between securities credit and futures performance collateral. Use Margin Account for buying on margin, broker loans, margin debt, buying power, interest, and security eligibility.
Margin Call explains initial and maintenance requirements, deficiency calculations, and forced liquidation. Borrow Fee covers the separate cost and availability risks of borrowing securities for a short sale.
