Margin Call Amount 1

题目

A long futures account starts with initial margin 6000, multiplier 50, and settlements [100, 104, 101, 106]. Maintenance never binds on this path. Treasury sweeps out any end-of-day balance above the initial margin, leaving exactly the initial margin in the account after each close. Ignoring interest, how much cash is withdrawn in total?
