Actually I am not a newbie and have been burned by some good ones as well. I disagree with your MM designators on the Ask as well. UBSS, AUTO are clear diluters; NITE use to be the worst but I believe has taken a 3rd position behind these two.
When you do a chart (as you well do) the most glaring indicator is the Accum/Dist. line. It shows clear dilution of close to 60MM shares! The good news is that it hasn't fallen further in the last few months, so maybe some positive developments with that indicator are forthcoming.
