Thebeatgoeson: The official 2015 volume in CGNH was over 40 million shares. Anyone who believes the volume was 20 million shares simply does not understand how the market operates. That conclusion appears to be justified when you post volume figures and state they are actually trades. If you have the ability to utilize due diligence call the Market Regulation department at FINRA or the complience area at any Brokerage firm and they will inform you that most trades are made on-line. They will also state that if a broker receives a customer order they will not buy the stock from someone else and sell it back to their client.
