Before you guys beat up on Bryce and lump him in as "just another vendor", you should at least understand his body of work. Unlike TI who operate as a pure advertise & scam vendor (i.e. expensive ads in trading magazines, expo booths, share no real info about the subjective method, use extremely simplistic approach, have no credible references, lots of complaints from ripped off students), Bryce falls into a different category.
Bryce has a body of work, he has done a ton of seminars, he has references, reviews, & interviews from many other top or well-known traders. He's been around "in the business" for a long time and the # of negative reviews, proclamations of "yet another guru scam", BBB or CFTC or similar complaints, etc. do not exist as far as I can tell.
Bryce has had many typical "anti-guru detractors" on various message boards and mailing lists (including Usenet) over the years, so if you want to go back the last 15 or so years, there is plenty of material out there.
Now... whether this methods are profitable, whether you believe in market geometry, whether there is other value in his trading course/mentorship style -- these questions you will unlikely have answered here due to subjectivity & complexity of the data vs. what TI/Franz were selling.
While I make no judgement either way (an exercise I leave up to the reader), I want to bring to your attention this major differentiation between TI/Franz and Bryce. A very important disctiontion is that you can review Bryce's body of work. You can read reviews about his body of work. You should be able to find copies from others to borrow on various forums as they have been around awhile, traders library for rent/exchange, or purchase on various used book marketplaces. Some are even available for free.
