Now it's confirmed. We have entered bearish phase. Dailies show the significant break of higher high and higher low.
I plotted areas where it is best to short:
23.6% = 163.65
38.2% = 164.15
50% & previous day's high = 164.60
61.8% = 165.00
For bullish traders, there's a small window of opportunity to enter now at 164.10.
