Still pretty nice for one one day's work... where can I check for any more rights issues, or similar news that can be traded like that..
you will have to search the SENS. I must warn you though. Trading in the rights offer shares is highly risky, as in some instances they become worthless. Make sure you only trade in liquid companies like WHL. Look up a company with the code ECS. Their rights offer shares are currently being traded at 1c each and sellers will be lucky to get even that
