There were many times in the past that I would put in a limit order at the ask price and get filled at the bid on the CT's. The MM's can do as they please with these pink sheet stocks. Grey's are even worse. SEC suspended trading on one of my other stocks today, which is very rare here in the Wild Wild West.
All the above is my opinion, after all who would believe me anyway since I drive a 1975 Vega!
