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.
