Some general updates and a comment on FRASMA

Let me apologize for a rather long silence, I've been studying some more fundamental problems that require me to revamp and improve a bit my knowledge on various mathematics topics.
I shall try to resume posting more frequently whenever I find something interesting, and anyway, I should at least be able to post some more basic stuff after summer.

Meanwhile, some people left a few comments on the MQL4 community, particularly on the thread concerning FRASMA that may be of interest for those using this moving average.

hi Jean-Philippe,

do you think that spikes in fgdi volatility meter create rezistance area for counter-trend moves maybe a heat-map of some sort could be drawn in the price chart as a function of either a density or volatility of trading. for example red rectangles in mt4 platform. i just thought that price in the area where there was heavy trading in the past is susceptible to pullback, because the heavy trading is returning in those areas. (its probably not a rule, but im sure you will find some new links in analyzing charts stock indexes are good for it).

i accidentally came across a software that trades elliott wave patterns and the graphical outcome in future target projection seems very simillar to what i had in mind. this is probably based on a fibonacci arcs projection. i dont know if arcs are better than horizontal linesbut the goal is to display future rezistance map. http://www.forex-tsd.com/attachments/harmonic-trading/89779d1252653581-modern-elliot-wave-trading-using-elwave-gj_h4.jpg

Hi Martin,

If I understand your remarks well, you seem to raise the problem of analysing the variations of the fractal dimension. It's a very interesting question but a very difficult one as well, as of now, I have no answer to your questionning, at least from a mathematical perspective.
In other words, I don't know if sudden changes, high activity in fgdi movements do indicate anything of value for trading, it may be so, it may be interesting to do a spectral analysis of the signal built by these variations of fgdi, but I still have not figure this out. All this belongs to a multifractal analysis and I am still not very knowledgeable about it, though I may develop something in this area in the future.
One thing we must keep in mind though is that what FGDI provides us with is only an estimation of the fractal dimension, taken on a finite number of values, as of now, I am trying to improve this estimation, and will hopefully publish something soon about it. a better estimation may give us more insight on the variation of the fractal dimension and open some perspectives in view of your question.

As for the Fibonacci arcs or levels, yes, I believe they are of interest as well. Even though, here again, I have not succeeded to link them in a mathematical manner with real price evolutions, despite that, this is one of my long-term goal (or maybe should I say dream).
And I can't argue in favor of arcs or lines (though I personally use lines more often), it may be a subjective thing, maybe relative to the instrument traded, but I have no argument to advocate one over the other apart a personal bias.

cheers

Your blog keeps getting better and better! Your older articles are not as good as newer ones you have a lot more creativity and originality now keep it up!

Thanks for your support.
I'll try to keep it up, though I am still a bit busy these days, just moved back to Singapore, and still not settled yet.
Hopefully, things will get back to normal in the next few months.

Cheers
