I have been a W.D. Gann enthusiast since the early to mid 1990s. Let's put it this way - the internet was in its infancy and dial-up was all the rave. 😂😂 Man have we come a long way!
I purchased his Commodities Trading Course From Nikki Jones in circa 1995/1996. I want to say something to anyone that's just now motivated toward or recently began studying William Delbert Gann's life work - the study of cycles, law of vibration, square of 9/12/52/144: You have it a lot nicer than we had it in the 1990s. Unless you were rolling in money and could afford to go to seminars, etc.
We didn't have the internet like it is today. Anybody with a smartphone today has the world in their hand. Be happy! The struggle was real back in the day.
So, I said all that above to bring your attention to the below article about Dr. E. A. Crawford mentioned in "How To Make Profits In Commodities" on page 22, and other Gann books and materials. I, for a long time thought he was a fictitious character. He's not! The luxuries of today's technological advancements allow you to Google any and everything.
A closing word, don't give up. Read Gann's Tunnel Thru The Air. I mean READ GANN'S TUNNEL THRU THE AIR! Study that book. Take notes. Treat it like it's more valuable than gold because it is if you educate yourself on it.
