If this is correct the 3 wave B is finished or close to being finished today. One more high would not be a problem as the 100ma and Upper BB are both around 389-391 on SPY. Personally I think this may be a bull trap with a C coming before the bigger move up into the end of the year.
Today could continue the rally, to further convince bulls and bears that the trend has changed and we are going higher, but the MA's/BB resistance tell me otherwise. Good luck!
