I was referring to when CSTI and NITE are tossing the ball back and forth to each other like today. Together they are the abusive naked shorting dynamic duo. Either acting alone would make me lean toward retail.
Interesting find on the Speedtrader trading platform. Look near the bottom of the page to see the available ECN's available for direct routing of orders through Speedtrader. Some very interesting, and ominous, names listed.
