Futures is a kind of financial derivative, which has the characteristics of high risk and high return. In futures trading, Ping Jin means that the contract bought on the same day is sold on the same day, so as to complete the transaction on the same day without having to bear the delivery responsibility when the contract expires. Flat trading is generally suitable for intraday trading or short-term investment, which helps to trade quickly and reduce risks.

Ping Jin trading is very common in the futures market, mainly because Ping Jin is flexible, convenient and efficient. Compared with other trading methods, the risk of Ping Jin trading is relatively small, because it only needs to complete the transaction on the same day and does not need to bear the risk of due delivery. In addition, Ping Jin trading is also conducive to the flexible use and adjustment of short-term funds, helping investors to better grasp the market rhythm.

It should be noted that daily trading must be conducted within the trading hours specified on the trading day, and the specific time varies with futures varieties. When trading in Ping Jin, it is necessary to ensure that there are enough funds and deposits in the account, otherwise the transaction cannot be completed. In addition, Ping Jin's trading should also abide by the relevant trading rules and market analysis, and the specific operation should be cautious and rational to avoid possible losses.
