Using Fibonacci Retracement, Elliot Wave, Pitchfork Tool
BTCUSD on Daily Chart shows clearly for the possibility of the WXY correction to extend into WXYZ correction as the impulse wave at the end of WXY is a three ABC wave. It is also contained within the channel shown. The channel levels shown are Median, 0.382, 0.618 and 1. As far as current sentiments goes I believe this is how it will be played in the next 21 days in the white time bar :
By simple most often used Fib-Elliot Wave analysis (I called it FEW), the Z target zone is between the 78.6% to 144% retracement of the major 5-wave
As I am still a newbie, I don't have sufficient knowledge of the probability aspects of FEW but looks like at hindsight the most probable will be between 50% and 61.8% and if this is broken then the next target is 78.6% or even the unlikely 100%
If you know how to calculate the probability of the FEW, kindly do so here in the comments below.
