Dot trading is at no cost,played by the contracted institution player. This is a very common skill, dot selling is for accumulation, and dot buying is prepared for further upcoming dumping.
Normally it is used for boring impatient sellers and impatient buyers as well.

In PLA case, clearly is the dot sellling dominates the accumulation.
