In checking for forced buy-ins I neglected to look closely at the trades at the end of the day....There were 5 with a Q code which means they're MOC trades or "Market on Close".  Basically that means they were Market Orders (not limit orders) that are to be transacted at whatever the closing price was.  

All the buying was by 007 so it was through TD, the sellers were 5 different houses.  It at least has me wondering if maybe someone knows that news is coming out soon and so put an order in for 6,300 shares at whatever the closing price is....no matter how low or high.
