SPX the channel for the 18day cycle will have an upper bound at end of Friday of approx 2965. A rally to this area, or slightly above, followed by tech signals of failure should be sold, IMHO.
The 30min cci for 9days is OB, and for 18days is on the way up. A sell by the cci for 18day would likely be successful, IMHO.
Oddlot
Stay on the right side of the cycle!
