题型：单项选择题

It is April 15, and a trader is entered into a short position in two soybean meal futures contracts. The contracts expire on August 15, and call for the delivery of 100 tons of soybean meal each. Further, because this is a futures position, it requires the posting of a $3000 initial margin and a $1500 maintenance margin per contract.

Assume the following represent the contract delivery prices (in dollars per ton) that prevail on each settlement date:

April 15 (initiation)

July 15

August 15 (delivery)

173.00

179.75

189.00

182.50
