I've been seeing this since yesterday --- .0002s were NOT painted at the close.
Example of a paint: .0001s been hitting for most of the day, for tens of millions of shares ... then 5min-1min just before the close, someone buys [let's say] 200k shares at .0002 --- at it closes at .0002. That is a paint-job.
What happened here was: tens of millions of .0001s were being sold into the Bid; with very small, isolated smattering of hits at .0002. Then, in the last HOUR, no sells (?) into the Bid of .0001s. Instead, 6 sporadic trades, totaling 6.250mi shares in that last hour ... not an EOD "last minute" paint job. Which, btw, could have been easily erased by say an EOD hit into the Bid.
Now the 9mil-ish shares bought at .0002 on Friday cannot compare to the 200mil plus sold into the Bid of .0001s -- but hey, the week ended better than it started.
