Novo2018: Not to go off topic too much but I just spoke to another agent at my broker. He said certainly I can sell my WRM shares bought on the ASX on the OTC. He said by default they usually go with the exchange it was purchased on but he could sell it on the OTC if requested. I asked if there was any significant pre-step and he said no. He can do it almost immediately, once WROCF becomes active I guess.
Guess I will find out for certain when I sell the WRM share at $20 one day
