I beleive his first work was the enhancement to vto's rsi 5 daily system, with a scaling in approach.
He then went on to demonstrate an hourly rsi 5 system.
The current one is primarily based on 15 minute bars with a 48 period cci.
I don't myself have the time for day trading because my IT job can go from quiet to madhouse in just a few minutes. About the best I can muster for 'fast trading' is the merlin system, which I am now trying out. Disclaimer merlin is a paid svc.
As to daytrading, you probably are aware but this board is very heavy on it, many members have several screens and quite the exotic rigs. So, if thats not your cup of tea, this may not be your best area for learning.
Beyond that there are succesfsul daytraders, mutual fund investors, Warren Buffet et al. Whatever floats your boat as long as you don't fall into the trap of thinking 'my way is the ONLY way'.
Only bottom line net profits matter, the rest is chat.
What is your own approach and how is it working out for you?
