Shorting makes the price fluctuate more frequently, so the price will not go up so easily, which may also accelerate the deterioration of the financial crisis. However, if there is no short selling, futures cannot exist.
To put it bluntly, shorting futures is to be a seller in the contract and want to complete the trading behavior of selling high and buying low.
Empty speculation in the futures market is generally that the seller sees that the price of futures products will fall and sells them at a high price in the contract. If the price falls, he can sell at a high price and buy at a low price to make a profit.
In the futures market, the speculative manipulation of the empty side is generally based on the principle that all forces are mobilized to push up the price of a futures product, resulting in a false situation that the futures product is about to rise, and then high-priced contracts are signed with many parties to attract the king into the urn, and the empty side begins to smash the market, and the futures price plummets, thus making profits.
