CoachA performance bond is the futures industry’s name for initial margin: collateral deposited to guarantee performance, not a down payment. For a client account the broker sets an initial level, required to open a position, and a lower maintenance margin: when the account’s equity falls below the maintenance requirement the client is called to restore it to the initial level. For clearing members the two coincide.
