hi mladen,

thank you very much for the indicator.

now i have three different indicators which all give different results

cheers,

mike

If you take a look at the calculation, the one I posted does it the way defined here : Hurst exponent - Wikipedia, the free encyclopedia .

But even when compared to Fractal dimension as defined by Sevcik and if we take the Hurst = 2- Fractal dimension, the correlation does not stand (the original Sevcik's fractal dimension has flaws, btw, since it never reaches values of 1.5). In my opinion, the one I posted is OK but I leave you to decide what is what in the "hurst exponent mess"

regards

Maybe this additional info will help

___________________________

If we strictly take the definition that Hurst = 2 - fractal dimension, and then we compare the Hurst exponent to fractal dimension, than the one you posted corresponds to Alex Matulich's inverted version of Fractal dimension (he took original from Carlos Sevcik and corrected the flaw I was talking about - if one takes the Carlos Sevcik original basic code and applies it to the letter, then the values of 1.5 are never reached, which is an error). Alex Matulich took that code an corrected it. Here is an example how does Alex Matulich's version correlate to the one mike posted
But, as I said, the one mike posted is actually the corrected Alex Matulich's version inverted to give the defined (Hurst = 2 - Fractal dimension) Hurst exponent

But one more but . Since Bob Fulks and Alex Matulich did work together a lot and since the version of Hurst exponent I posted is done after the work of Bob Fulks, and since he done it as defined at that link (link from wikipedia) that describes Hurst exponent in detail, all we can do is come to a conclusion that there is something wrong in the whole thing : they roughly correlate as expected, but just roughly. The question in the end becomes the "which is the older" question : Hurst definition or Carlos Sevcik's definition.

_______________________

And if we all this was not enough then if we additionally include Mark Juriks fractal dimension, than we get even more confused : Mark Juriks Fractal dimension has absolutely nothing in common with previous versions.

_______________________

Attaching Juriks version (the "Fractal dimension") as well as original Sevcik's version (that is the "to the letter" Sevciks version with the flaw I was mentioning) and Alex Matulich's version of fractal dimension so that all can be compared (here is how does that comparison looks like) :
That is all from me regarding Hurst exponent and Fractal dimension. I did read once a study that fractal dimension / Hurst exponent can not be applied in financial markets (it was related specifically to financial markets and a lack of some things necessary to be able to apply either of the mentioned) with some proofs for that, but after that I was trying to find that site again and I always failed, so please do not take this last part to seriously : I really do not remember if it was "that serious"

Hope these will help a bit

value chart + price zone ascillator smoothed

Dear Mladen,

i use value chart (bars are not visible) with price zone ascillator soothed in one window. I wonder, is it possible to make a indicator that generates alarm (email) when price zone ascillator cross emas (see picture). This system generates very good signlas on renko charts especially when corss is near +-8 value chart.

Could you make that indicator?

Thanks so much!

Mladen,

Is it possbible for you to implement the genetic algorithm library JQS UGAlib - MQL4 Code Base in value chart for optimization purpose?Many thanks.
