There is an indicator for monitoring short-term crashes. Previously, people needed this indicator because significant crashes were often caused by large players dumping prices or certain large positions being liquidated, allowing for 'buying the dip'. Therefore, whenever a major crash occurred, everyone waited to pick the bottom. However, in this round of market, this indicator has evolved into a new strategy. Now many people are watching the crash monitoring to determine if it's a good opportunity to short, as a crash often leads to a new round of even larger declines after starting from $OM.
