This afternoon's trading logic:

Figure 1 shows the data checked this afternoon (with time markers). At that time, I noticed that the capital flow data was not very healthy, and the difference in short-term changes in the positions of the two contracts was too large (the position of the coin increased while the total value of the contracts decreased, proving that the main force was opening short positions to close long positions). I decisively opened a short position during the rebound. Those who are familiar with my analysis process should understand; I often posted similar coin analyses in the past.
