Jack, Only one of hopefully dozen's of things one should/COULD consider before investing (emphasis on could for effect.)
One *could* also consider counting up the number of "7"s that appear in the closing price, expressed with 2 significant decimal digits to the right of the decimal point.
No 7's = no signal; hold One 7 = strong buy Two 7's = sell Three 7's = buy
I'm sure I have your take on this - you've made it clear so there's no need to continue.
