DislikedYou were correct that was a no supply bar.
I only glanced at the chart for the second, but I'd believe you marked a valid NS bar as it was a down bar with low volume that followed climactic volume.
Per Clif's methodology this would be considered an aggressive entry.
In my mind a NS bar doesn't necessarily have to be a down bar, it can be down for most of the bar's formation and then close slightly up, and as long as it broke the prior two bars' lows it means the same thing; lack of selling interest.
Don't beat yourself up about not...Ignored
