V3 doesn't just show you every event that occurred, it allows you to scan those events to locate each instance of a particular market behavior. Scans give users the ability to quickly locate different types of behavior, and once located, users can drill down to the event-level detail. The image above shows the results of a scan looking for every trade sweep that moved 5 or more price levels and had an aggregate volume greater than 100.  As you can see, there were a total of 4 times when that behavior occurred in that particular trading session. 

Being able to get to that level of detail allows users to understand what was going on before and after the event, giving them the tools to understand the importance of the behavior.  So if they were to see it again, they can have a plan of what to do.
