Cutting positions is a flat stop-loss measure to prevent excessive losses after opening positions or when the positions held are opposite to the exchange rate.

The real warehouse means that the main force obviously wants the stock price to go up, but because some short-term buyers use chart analysis to follow the trend, or receive the gossip of stock purchase, and the main force does not want these people to "make money in a sedan chair" for nothing, they obviously want to pull it up, but deliberately beat down the stock price. Most short-term speculators are buying up and not buying down, or chasing up and killing down. When the stock price unexpectedly falls, many short-term followers will lighten their positions and be "shocked" by the main force. Some people call it washing dishes.

The whole process of futures trading can be summarized as opening positions, holding positions, closing positions or physical delivery. Opening a position, also known as opening a position, refers to the new purchase or sale of a certain number of futures contracts by traders. In the futures market, buying and selling a futures contract is equivalent to signing a forward delivery contract. If traders keep futures contracts until the end of the last trading day, they must settle futures transactions by physical delivery or cash settlement. However, only a few people make physical delivery, and most speculators and hedgers generally choose to sell their futures contracts or buy back their futures contracts before the end of the last trading day. In other words, the original futures contract is written off by a futures transaction with the same amount and the opposite direction, thus terminating the obligation of physical delivery at maturity. This behavior of buying back a sold contract or selling a bought contract is called liquidation. An open contract after opening a position is called an open contract or an open contract, also known as a position. After opening the position, traders can choose two ways to close the futures contract: either choose the timing of closing the position or reserve it for physical delivery on the last trading day.
