From the speed and velocity of the drop after at 2040 is broken, there is another second wave of selling coming.
Watch any rallies in the coming days and weeks. Its probably a rally, for the next leg down. Therefore, enter short either at resistance A (1970-1990), or resistance B (2040). Take profit target at 1820.
Also notice the potential for H&S pattern to form with either scenario.
Compare it to the Oct 2014 drop and you have a neck line into the future...break that after a bull trap and ashes ashes we all fall down...
I realistically see us potentially making it into the 1730s if we break the Oct 2014 low support.
