Andy, thanks for posting. I am an active put trader (selling only) and have not seen what you describe. I understand “getting put” as that has happened to me many times but then you end up owning shares. Did this have anything to do with margin? I read that the margin needed for CHL options went to 100% so maybe it is a margin problem. Please post the outcome when it is resolved. I am sure that I am not the LI member with interest. Good luck!
