Using this post to discuss a method of monitoring. Some people have channels to monitor the changes in the position of exchange contracts, or they directly monitor the changes in short positions. In the future, when encountering similar situations, take the position data before significant market changes as a starting point and monitor for abnormal growth ratios of 3%, 5%, and 8% to push alerts. This may allow you to capture sudden situations in real-time. A long time ago, there was a paid feature called Contract Emperor that I used, so I know this method, but later I stopped using Contract Emperor.
