There was no real correction since 2012 - monthly YM

black line is 200ma montly
if i use gann fan, the succession of up and down was realistic till 2012
monthly you can see that all the tries to go down were stoped before completing the gannfan
last march was a ajustment for 2016-2017, but nothing connected at 2012

so i draw my gann fan and then complete a normal triangle period over it, so IF it goes down, that bottom is a probability
