When the 10 day suspension ends the stock might trade on the greys for a while until the formal revocation of the ticker occurs. From my understanding there will be no bid/ask shown, no market makers and just matched trades only (no solicited trades).
In one grey I own only the last trade is shown,which is often dated due to scarcity of trading, however that might be different in a case with many shares like we have etc.
We should see a bit of what might happen with UOIP comes off 10 days and trades greys since that was suspended before WSTI by a few days..
Everything I post is my own opinion and people should always do their own research and due diligence on any company they are looking at
