Can someone please help me understand the following warrant action today. The trades are posted below. So Troxw trades at a high of $79.00 at 15:53:52 and then four minutes later it trades at $77.25, also it closing price. Troxg trades at $73.00 at 16:07:00 and the closing price is $70.05. A closing price at which is never traded at all day. Why isn't the closing price $73.00. This seems odd to me. Please help. Thanks
