Trend,

Someone on twitter has discovered that 40% f the trades post crash were by "dark pools", usually reserved by large institutions.

I cannot read the chart due to my color blindness, and can't tell whether that was large institutions dumping shares, or picking the up.

1. Can you confirm this is the case from the chart below:

2. If this WAS the case, was this "dirty pool" (pun intended) used to pick up large blocks of shares, or to dump them?
