That's a good question you asked. It seems that you study hard. Almost all mature futures traders look at the market every day, always staring at the changes in the ratio of closing positions, long positions and short positions, as an important basis for deciding to enter the market. I've been looking at these important data with master Bo Yi. Tell you what to think: first open the time-sharing chart of the variety you want to trade, remember! Must be a time-sharing chart, and then press the keyboard shortcut F2, the data will come out. As for other market software, I won't explain them here.
