Paul Tudor Jones used Elliott wave theory. Stanley Druckenmiller looks at charts http://mastersinvest.com/chartsquotes
I agree with most of this, though I've never seen evidence that a 14-day RSI has any edge. The only edges I've seen are long-term momentum beating buy-and-hold on a risk-adjusted basis. There used to be trading systems that bought short-term weakness during long-term uptrends that had an edge as well. For example, buy a 7-day low when the S&P 500 is above its 200-day MA then sell the next 7-day high--or something like that. From what I can tell, they lost their edge when books started promoting them and automat trading systems started using them. Also, I haven't seen any edge in volume, though I haven't really studied or systematically tested volume profile or modern adaptations of Wycoff. But simple volume or volume+price doesn't seem to provide any real, repeatable alpha.
A line on a chart I trust is price. And I trust it more than I trust any human. Including the great investor of the insurance cash machine monster he built Warren Buffett.
The only deception is .... you actually believe that. Note that I day trade. Nothing to do with long term viewpoint. That I could care less.
i think quants are the only "techies" that make money long term. The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution, Citadel, jump trading, etc Sure they don't use swiggly lines like most retail traders, but they use fancy math on price data. Isn't that what technical analysis is? coming up with a mathematical formula to read the markets.
No, because Citadel is a market maker, and they have much better data than anyone else has access to. Quant models aren't the reason they make money, volume data and buying data is, though.
Yes, plus plenty of math geeks have tried using "really fancy maths" (neural nets, chaos theory, Fourier Transforms, etc.) over the years without any consistent edge. Basically Simons edge is HFT, probably optimized by a bunch of math geeks.
If you believe that, TA can never work for you. So it makes no sense to teach you something that you don't believe in.
