First I understand to trade in the GREY market the bid and ask must exactly match. So how do we get strange numbers in the shares traded volume like 163,397?

Imo there must be some brokers calling each other to arrange deals. One would expect to see trades in round numbers like 1,000-3,000-7,000 etc. not numbers ending in 397.

The price is going up, not really on convincing volume, but some neverless. There defenitly could be some manipulation going on, crosstrading etc. But then again there just could be speculation going on at the same time.

I see that the longer this goes on without an update or news the harder it will become to trade without an MM.
