Yeah, that's what I would do. So technically they are worthless to you, but they aren't really worthless unless they no longer trade because you can still sell them. That's better for you. I really don't recall what other brokers do in this case. It's been so long since I traded otc's. But I hear you on the Etrade rant. Morgan Stanley has ruined that brokerage. They used to be so much more customer friendly to active traders. Now they nickel and dime you for everything.
Just tried to remove two "worthless securities" from my account so I can get some losses to offset my gains. Both of these securities have no bid or ask. But there has been some activity - not much but I can see volume on some days. Tried to put in a sell at .0001 (lowest etrade allows you to enter) and nothing filled. So I spoke with a broker and they said they can not remove these securities as "worthless" unless the stock had gone 30 days without activity. This I never knew. So if you are looking to get rid of something like that keep an eye on the volume during the month and if you see 30 consecutive days of no volume they can write them off for you.
