Well, this is not an high net worth individual doing that or a punter, it's pros.
Reloading so that not to completely destroy the share price
Making random(ish) packet sizes
Leaving some positions OVN whilst adding/ removing the short term positions daily.
According to my own feel, probably 50% of the whole sell side is one actor. Whereas it's a broker or a early investor fund is moot. But it's pros.
