According to the regulations of Zhengshang Institute, the two-way positions of the same member, the same customer and the same contract month shall be charged with the trading margin according to the big unilateral position.

The meaning of large unilateral margin (for example)

For example, suppose that the soybean meal 190 1 contract is currently 3,000 yuan/ton, and investors make the 190 1 contract at 3,000 points, and the soybean meal 190 1 contract drops to 2,990 yuan/ton. In 1990, soybean meal 10 lot 190 1. At this time, the intraday occupancy margin = {3000 *10 */kloc-0 * 9% (the margin ratio is 9%)+2990 * 10 * 65438+.

The settlement price on the day after closing is 3 100 yuan/ton. After the settlement, the exchange will collect the unilateral margin according to the settlement price of the day, that is, 3100 *10 * 9% = 27,900 yuan. After the settlement is completed, the overcharged part will be returned to the available funds in the account.

Suppose that investors close more than 8 lots of soybean meal 190 1 contract on the second trading day. At this time, the investor's position is soybean meal 190 1 multi-contract 10, and the intraday futures margin is (3 100 * 10 *). There is no deposit for more than two orders.
