....there's something else.....
... if using price.... after that big retrace... you might guess the bottom was a 50% extension
... or a measured move down.....
... using price alone... it was much more than 50%
... but now that we can see the new channel.....
..... you can see that the big retrace was in fact at the 50% mark... of the new channel.....
... .something else to remember
