In addition to these, it is the deposit system. For example, if you want to buy raw sugar now, the contract price of raw sugar 1 109 is 7 198 yuan/ton, and raw sugar 10 ton. If there is no margin system, you have to buy primary sugar 7 198 * 10 = 765. Then under the margin system, you only need 71980 *10% = 7198 yuan to buy sugar. If you buy more sugar in one hand now, and it rises to 7298 yuan/ton, your current profit is (7298-7 198) yuan/ton * 10 ton/hand/10%= 10000 yuan/hand, which But if it falls to 7098 yuan/ton, you will lose 10000 yuan/hand. Doing futures is to judge whether the direction of futures trend is the same as you predicted. If it is the same, you will make money, but if it is different, you will lose money.
Then there is the T+0 mode, which can close positions on the same day, and there is no limit to the number of positions opened and closed. For example, if you buy a hand of sugar now and find that the direction is reversed, you can immediately flatten the list in your hand.
As for software, the trading software of each futures company will be different. The trading software is generally Wenhua Finance and Boyi, and the trading software is Jinshida, Boyi's lightning hand Yisheng and Wenhua's one-click order.
Like stocks, futures are charged, and different kinds of futures companies charge different fees.
