"Firstly, they choose their moments by XT (cross trading) shares from account1 to account2."
Rocket I have been monitoring the daily course of sales of CDY but only for the past week.Only very light volume. There is an example of what you have indicated occurred on the last trading day with an XT dropping the price from $0.25c to $0.24c. Hard to know how genuine it was but will be interesting to see the open when trading resumes.
