I know I've mentioned this before, but I am just sick and tired of this trade practice.
Every time the price goes up, some trader flicks off a parcel to bring the price back down. This automatic flicking is getting really annoying because it not only keeps the price down in the red, but is effecting the charts with an abnormal pattern. The parcels are always small - and the dishonesty is frustrating.
Watching some idiot sell into himself with small parcels to coerce others to sell into his bids is just plain annoying. It seems to stand out when dealing with small caps.
