Suppose you buy a stock index futures contract (long on index future contract) at the opening price of 452.25 on July 1. The multiplier on the contract is 500, so the price is $500(452.25) = $226,125: You hold the position until selling it on July 16 at the opening price of 435.50. The initial margin requirement is $9,000, and the maintenance margin requirement is $6,000. Assume that you deposit the initial margin and do not withdraw the excess on any given day. Construct a table showing the charges and credits to the margin account. The daily prices on the intervening days are as follows
