Short-term trading is all about Inventory getting too long and inventory getting too short. What he means by that is first we need to identify who we are competing against. If it's short-term participants, they will build positions on one side, and if they cannot push markets on the side they build their positions, they will flush out,( measure also via time ). To estimate what they were up to and how good a job they were doing is the catch. Hope that helps.
