Since making the top at 580.99 the PA created the megaphone pattern (descending widening wedge). The swings within the wedge made an astonishing pattern. PA retraced exactly to the 78.6 - 88.6 fib. zone on every single swing low. No coincidence, since this occurred 4 times so far!
According to this, the next swing lower should retrace to the 78.6 - 88.6 zone again for the 5th time.
