No such thing as Free Markets. But yea, PPT is real. Didn't the Fed protect us all from BSC going "BOOM" ? Not that I agree with it.
I do not know which way to vote, but I have noticed a multitude of times that the bad calls made here on ET are blamed on PPT or some other dark forces of interference.

I agree any trader that uses PPT as a scapegoat for their loses is a joke. However there had been a dozen posters or so in the past that would reply and scream there was no PPT.
