Futures contracts are based on margin. Take the example just cited, when you sell at the price of 10, you should provide a certain margin, because if the price has not fallen or gone up, for example, to 1 1, then you must return the goods at the price of 1 1. The deposit may be gone. Of course, if you think it may fall, you can continue to wait, but you may need to add margin, otherwise you may be forced to close your position. (it can be understood so simply)
