While I don't want to try to answer my own question I can see there is 5 months between the Feb 17 and July 29 and Dec 28 Bradley dates. And using your 270 day (180 degree) concept 5 months is about 1/2 a 9 month cycle period. Perhaps there is a connection here. Being it is also based on Astrology I'm sure there has to be a connection on these 3 dates regardless of what market we are examining. All freely traded markets are affected by the bullish or bearish mentality of the traders regardless, and they peak and trough at these points no matter what the actual values may be.
