Backhand is the reverse operation. If the buying trend is wrong, you can do it quickly, that is, sell and open positions. \x0d\\x0d\ is the easiest to understand. For example, how many double-handed corn you have now, that is, you bought open double-handed corn, and the market is in a downward trend. Your backhand operation is to flatten the multi-single double-handed corn, and then sell the empty double-handed corn. \x0d\\x0d\ From the results, you hold two positions, but the position direction has changed from multiple orders to empty orders. \ x0d \ x0d \ futures are two-way transactions. During the consolidation period, due to your own misjudgment, such as building more, but falling, immediately close the position and then short, which is called backhand.
