Trading information belongs to the handicap language, and it is one of the analysis tools of intraday short-term trend. Traders can judge the trend of futures prices by the direction of trading.

Long opening means long opening, long opening means buying, and long closing means selling. Bears are bears, bears are selling, bears are closing positions, and bears are buying. The rise or fall of futures prices ultimately depends on the strength contest between long and short sides and which direction the price will go. What we can see from the trading information is that as long as the bulls are bigger than the bears, the futures prices will easily rise, and vice versa.
