Wu learned that Binance's investigation showed that the "large short orders" before the GPS announcement were normal market fluctuations and there were no abnormal transactions. The active selling volume 10 minutes before the announcement increased by 1.78 times compared to the previous 5 minutes, but from a longer-term perspective, fluctuations of 1-4 times are within the normal range. Historical data shows that GPS active buying or selling volume accounts for 40% to 60% of the overall trading volume, and there has been no abnormal change before and after the announcement. Proactively selling may be either opening a short position or closing a long position, so an increase in trading volume does not necessarily mean that the trader has pre positioned short positions. In addition, there was no significant change in the total amount of open contracts within 5 minutes before and after the announcement, further indicating that there was no abnormal trading behavior in the market.
