Re: The Normality Assumption and Fractal Nature of Asset Prices

Flojomojo, a Preface: Even though it will most likely push some head buttons, this is (paradoxically) not a disagreement with your posts

But! … after nearly 25 years of “turning charts every way but loose” , I have concluded the following needs to be said plainly.

They lied to us. “As above, so below” – NOT!

Re: The Normality Assumption and Fractal Nature of Asset Prices

Prof, I am a proponent of constant volume bars for certain applications and have followed your arguments at other venues.

Might I ask is it your contention that time is an unimportant variable when analysing price series data? (I think I can guess what your answer might be )

As an aside constant volume bars with a time histogram below gives an interesting depiction of 'pace' or momentum (if such things are of interest).

Sorry FJM strayed a bit off topic.... good work though!

I don't want to pull this thread off kelter but yes time is irrelevant to price action. Adding time in a histogram is just adding an unnecessary distraction. Look at a clock if you must.

Re: The Normality Assumption and Fractal Nature of Asset Prices

Hey ppl...as there seem to be some controvertial viewpoints here I suggest to open up a new thread to discuss the relevance of the concept of "time" in trading.
Best regards,
Flojo

Re: The Normality Assumption and Fractal Nature of Asset Prices

Hi,

I understand the concept, to some limited degree, of the fractal nature of time-based price data... but wouldn't one expect that? Doesn't the price movement on a 5 min chart manifest itself on a 15 min chart which manifests itself on a 60 min chart which manifests itself on a daily chart, et cetera? How can one "predict" where price is heading by multiple time frame analysis using the trend of a higher time frame (e.g. 60 min) to assess the movement of a shorter time frame (i.e. 5min) when its the shorter time frame that ultimately makes up the higher time frame movement? My only answer that I can come up with is that there are "more" large traders that follow price movement on the higher time frames (i.e. 60 min and above) whose decisions and actions based off higer time frame chart points (S/R levels, pivots, et cetera) manifest themselves in the "immediate sense" at the level of the shorter time frames. I've struggled with this for a long time, so any feedback would be greatly appreciated to help clear up my muddled thinking! Thanks!

He there,
maybe the term "fractal nature" was a bit misleading in my post. The final chart in my post can better be describes as the timeframes being "self similar".

Yes, but this does not conclude self similarity of the different timeframes.
