I bought the stuff many years ago for $1500.
got a pile of about 60 inches high
started to sift thru the material.
about a third of the way thru it ---he became esoteric, supersticious, almost halucinating.
Gann had some basic good stuff. Squaring time and space is not bad. 45 degrees condept is not bad
even tho using it on P&F charts (as Stockcharts does) is most idiotic--since the whole
idea os P&F is to ELIMINATE the time axis (a line on a Cartesian chart requires both X and Y)
But the moment he starts into numerology, squares of nine, celectial timings, zidiacs--the stuff
is pure garbage.
Gann was god 30 years ago. Today , you hardly hear about him.
The only reason to pay for this stuff is the belief that there will always be
a GREATER FOOL that will pay you more in due time. Pretty good assumption.
