Real person gave a good explanation in regards to partial fills. I would like to add {in the many variables that could be added} that the main point of interest during these transactions is it reoccurring with seemingly set numbers and is it leading the price, up or down.
We’ll call it gamesmanship and it can be played , if the sets are right; by longs, shorts, mo mo’s traders, singles or in groups and that would include you and me as well. Anybody can play until they get ate up by somebody bigger.
In regards to the overview and with a eye towards a longer timeline it’s meaningless. Short-term, certainly, it can have impact but in the longer view it’s the fear and greed that claims the most victims
Anyway IMO
