That has been a problem for about a year. When stocks get dumped to the Greys, ADVFN's feed fails to reflect that. It used to do so automatically, but that ended sometime last year.
I usually write to Warren to notify him when a suspended stock resumes trading on the Greys. At least when I've been following it. He then fixes things manually. But the last time I asked, in connection with AXMP's reopen on the Greys, he said he wasn't able to override the data manually.
Whoever provides the feed needs to fix this. For 17 years, it wasn't a problem, and now it is.
