I agree with deaddog that chart reading is actually a skill, and your ability to distinguish charts providing good setups vs charts that don't comes with time in front of the screen. it's not just all noise. can throw publications at me, but I'll bet that the people who wrote those papers haven't actually traded, and were more concerned about the impact factor of the journal than the actual contribution they made to academia. Most chart traders would agree that it's more an art than a science anyway. But just because you can't prove something doesn't mean it's not true.
Ill rephrase with I agree most stock price action is noise but it doesn't mean you can't profit from it. There are many living proofs of this who have been around for a long time.
I reviewed his interview with Schwager and it seems he was a trader. To start he turned 5 grand into 200K. Then his returns in the 10 years preceding the interview were over 40% annually.
I very often take trades based on charts alone esp when I am too lazy to do DD. I have a rough idea of most tickers in my watchlist. About 700+ tickers which are all optionable. I do check up on news but ignore the fundamentals. Unless, your a long-term investor. There is really no need for that.
Forex trading is like art, there is so many ways to running strategy with the expectation to get victory in the game, trading without any indicator, only use candlestick is one simple way to trading setup, usually, trader focus on support resistance line based previous history.
%% That; + investor, fund manager, IBD founder, good data seller, book giver, NYSE seat owner....... He was a strange sort of educator, told the truth in an understandable way.,
I think you can profit from price action, but not alone. It's like saying you can be a great car racer by limiting yourself to just the rearview mirror.
Price action also takes into account the present. So it takes into account: The Past, and The Present. What else is there? The future? A "car racer" can see what the future road entails. Price action can't know that. Nothing in trading can know that.
