Neil if you looking to study something about mkts check the square of 12 chart out
the sp 500 loves the movements of 12
do some measuring and check it out play with it for a few yrs and see what it can do for you ...
did you see the sp500 top out at the end of the 3 rd set of 12 ?
then just bottom at 60 points down the 5 th line of the 1st square...
that is some heavy stuff to study
cheers
