Imho 2000 and 2007 were two different events. 2000 was a hugely overvalued SM, as in ’87, wheras in 2007 it was the Derivatives that pulled the banking system down, which in turn butchered the SM.
Plus in 2000 u did not have the Algo’s, as u do now. One can be sure that the scum have employed them, eg the 1 % rule in Gold.
Where I see them going wrong now is the way they are gaming the SM, which in turn must be allowing vast amounts of one way trading systems to develop, like the Vix sellers. Volume is drying up, so when those same systems dump, there will be no buyers and machines don’t have any logic, so they will offer until a bid is found.
The next bear may only last seconds, but wipe out 75 % plus !!!!
