Futures backhand, similar to reverse opening. Futures backhand refers to the situation that the original position is long and then the position is short, or the original short position is now long, that is, the position is closed at the opponent's price and the same number of warehouse receipts in the opposite direction are issued. Futures backhand mostly occurs when the futures market is misjudged. For example, if you now hold many lots of M 1505 10, the backhand operation is to close many lots at the opponent's price, and then open an empty order of m 10 at the opponent's price.
