"Chasing the empty" means that in futures trading, investors buy or sell at a higher price after the price rises or falls sharply, in order to get more profits. Specifically, if the price rises sharply, in this case, investors will chase up and buy; On the other hand, if the price drops sharply, investors will chase it down and sell it in this case. In a sense, "chasing empty" is a relatively high-risk trading strategy, which requires investors to have good risk awareness and market insight in order to obtain expected returns.

"Chasing empty" is sometimes called "naked selling" because it often requires investors to sell short without owning relevant varieties. In this way, investors may be influenced by other traders with reverse contracts, and may face risks if the market is unfavorable. Take foreign exchange trading as an example. Because there are bulls and bears in the foreign exchange market, if traders are not careful enough, most bears will easily get the upper hand, resulting in huge losses.

In order to successfully implement the strategy of "chasing the air", investors need to start from many aspects. First of all, it is very important to know the current market situation. Investors need to carefully analyze the current price trend, market prospects and various risk factors. Secondly, investors need to master the corresponding technical analysis tools and trading skills in order to make a reasonable trading plan. In addition, investors need to carry out certain risk control, such as setting stop-loss orders and observing trading rules, so as to protect their trading interests to the greatest extent.
