So I have a covered call option set to expire this week that i've kind of been mulling over to close out just in case some wild news comes out that shoots the stock up. Bid is 0 and ask is .05 "Last" is .04. I've seen this before in options where I have to make 5 cent intervals but the last is some odd amount that is most definitely not a 5 cent interval. Is it just my broker? I have Etrade.
