The reason scam trading gurus lean on technical analysis is because it's an easy sell for lazy people. It presents profitable investing/trading as an accessible skillset with a narrow scope of focus. Additionally, it's vague enough to keep losing traders on the hook for upsells.

Types of Quant Firms and Their Strategies (1/N)
Once a year I travel to a beach with good nightlife for a few weeks. I bring a math textbook with me. I crank out proofs in the morning, scuba dive in the afternoon, and party at night. Pure ecstasy.
It takes longer than one might expect to master the bare-bones basics (Probability, Linear Algebra, Statistics) but once you have these subjects down cold, the more advanced topics come rather easily.
Free edge. I can't say enough good things about this book. This book got me my first quant job. 99% of candidates fail basic regression questions.
Life hack, use notion to keep a running wiki of everything you know. The act of organizing all of your knowledge will train your mind for perfect recollection.
A Markov chain is one of the most flexible stochastic processes. Almost any random process can be adapted to or framed as a Markov chain.
I highly recommend taking a course in combinatorial and convex optimization. You will suddenly notice an endless number of problems that you can solve.
This book is a solid introduction to momentum strategies. It's targeted at equities but the principles of momentum translate to virtually any asset class. Highly recommend.
This is a very good probability puzzle book. I must say that the puzzles in here will be much tougher than most interview questions so if you crank some of these bad boys out - you'll be in excellent shape.
A very good introduction to the field. If you're getting started in quant, this book should be at the top of your list. It's also incredible interview prep for getting familiar with the industry.
Interview Prep Hack: Carry a probability puzzle book with you at all times. Throw it in your bag. Whenever you're bored, work through a puzzle. A great way to get those reps in.

Time series analysis is a good start if you were formerly a technical analysis believer. It will give you the mathematical intuition to understand precisely why TA is garbage. Extracting stable signal from noise within a time series in the absence of covariates is no easy task.
For every 10,000 struggling TA traders who are meditating, working out, and "finding consistency", there's an overweight portfolio manager in an NYC skyscraper snacking on Mc-nuggets smoking cigarettes' and banging 7 figure bonuses.
