Oh ! Actually I just remembered something that's also of paramount importance (Beside Fractality).
The fact that there is evidence of memory - Autocorrelation - with volatility. And not so with Price.
Wasn't that ? =P
Oh !! And that Time ain't actually "constant" ! Transcendental insight too.
If I were not an academic researcher, I would pay more attention to what ljyoung is saying because this is what most of traders talk about. Trendline, subjective volume trendline analysis, all seem relatively easier to understand and do even though it is proven that heuristic strategy generates negative return on average (results based on without incorporating risk management like stop loss). More importantly, we don't need to run the regression with 10 to 15 years high frequency data.
But since I understand what you're saying, I conclude that you are one of smart money (or at least you know about their strategy)...
