Very interesting. And the last 10 trading days or so it has been very apparent with crazy market moves. Though I'm curious to the extent of the efforts that would be required to find evidence of bids that vanish going unfilled. It's not a new trick.
These ETF's that have seen some serious selling on the run up. I can't remember the feed on ST and twitter now. Some big dogs were pulling the strings though.

Almost reminds me of the days before many of the ETF's were either removed or restructured some time ago.


Now where's our Prurisol data??
