Head and Shoulder in SPX500

Doing some charting and calculation in SPX as I learn that H&S is forming

Doing some calculation with 50% target which give around 1528
(slightly lower than 2008 high)

the timing is also fit my 2011 gann square that have a 1.33 to 1.5 time range.
so this should max goes to the early 2016

Thanks BM for the heads up
thank you BLM for the idea
