The cotton futures contract is 5 tons per lot, with 5 points in one hand, 10 points in two hands and 25 yuan in one hand.

Cotton futures are 5 tons per hand, and the minimum trading margin is 5% of the contract value. If the domestic cotton price is10.5 million yuan/ton and the trading unit is 5 tons, the contract value is about 75,000 yuan per lot, which is basically equivalent to other domestic agricultural futures contracts. Assume that the margin ratio is 65,438+00%. Then, the funds needed to do primary cotton futures are: 15000X5X 10%=7500 yuan.
