Yeah, I don’t know what the signal is that they’ll start selling, but no doubt they just constantly come in with contract dumps when they see any pause or slow down in the buying. They seem to sort of do the same thing in the shares except there they just start selling anywhere from 10 to 100 shares at a time to keep the pressure on until the buying finally exhausts itself.
There’s no magic to it, they have unlimited funds and access to data. They don’t worry about profits, it’s just mission oriented selling to keep prices down. They don’t worry about regulation, because they are sanctioned by the Fed.
They know full well what those charts look like and just use brute force to correct them.
The court cases brought against the banks are just a ruse for public consumption. Send a low level trader to a country club fed prison then take care of him for life. Fines are irrelevant because money is phony computer entries.
