I have no idea. I'm on the fringe of this situation and know they're working on it. There's been quite a bit of discussion and I don't know the particulars just that they are updating it.
No tickers have been removed. But in response to questions about why they were showing bid and ask for Expert Market issuers, they simply removed the quote and chart boxes.
That isn't the right solution. All that needs to be done is to replace the bid and ask with "N/A". But that shouldn't affect time and sales, since some do trade a little outside the U.S.
It may be that it's difficult to do. OTC Markets also shows no quotes and no charts, for these stocks.
