FWIW, I ran exactly about a years worth of QQQ hourly data and noted the order of daily LH. Out of 240 observations, the results were an astounding
50.4% L,H and 49.5% H,L ordering... talk about efficient.

Interesting topic.

I've been wondering if any provider has such a sequential ordering attribute embedded within (it would only take one column). It looks to be the only way to capture such information reliably is to have the higher frequency sampled data. For a long time, I just scrambled the order ...

Thanks all,

For whatever reason, I guess my question didn't come out too clearly. Sluggo, your approach makes sense; since if they are 'statistically' self similar, it doesn't really matter which direction you choose (well, ok only to start testing the hypothesis, the observational frequency ...

Thanks longmemory,

Your comments pretty much jive with what I suspected (or knew). So Octave/Gnuplot is essentially a substitute for matlab and variants. I've tried Scilab before, and the syntax or interface was horribly non-user friendly, IMO. In addition the supposed matlab converters (to scilab ...

bableproofreader,

Good to see other fans of R here. Just curious, what kinds of things can Octave do that R can't? And would Python/matplotlib be an equal substitute for Octave/gnuplot in your opinion? I'm approaching the opinion that R can do just about anything. However, there are a few things ...

Hello all,

I have seen a few interesting posts here and wanted to add some input to discussions. Now the following is a little off the wall; granted, but I was curious. A few posters have discussed Mandelbrot, and one of his key assertions is that fractals (of which markets mirror) tend to be ...
