a me servono dati in formato metastock
che dati ti servono?
serie storiche? di che titolo e di quale time frame ti occorrono?

Grazie Arosa...
ho iniziato da poco ad utilizzare Metastock (prima utilizzavo altro software). Non riesco a scrivere la formula per una benedetta MM centrata e la formula della sua velocità.
Volevo sapere se qualcuno (che utilizza questi indicatori ciclici ovviamente) è riuscito a svilupparli.Arosa

Non so se ci riesco ci provo dammi qualche giorno.

Ne ho trovato un paio vedi se ti possono servire.
Al momento non ho sottomano Metastock e non ho potuto controllare fammi sapere.

Forse questa e quella piu giusta.
Here is an indicator that compliments the channel plot. It’s derived from Brian Millard’s book “Channels & Cycles: A Tribute To J.M Hurst”. Have attached a screenshot straight from general use to show you how it might plot…you’re looking at the indicator with green and grey lines – which correspond to the two channels.
This basically will highlight completed/historical cycles on a fixed zero-reference (if you get the periodicity right). Try playing around with it….eyeball the peaks and troughs for a given approximate wavelength and then measure the average number of bars for recent full cycles using the MS Cycle Lines tool overlaid on the indicator plot. Then fine tune the input to the indicator based on what you measure. Trial and error should get you somewhere. Overlay a couple of plots for two major cycles and see what you see…
Of course there is the ever-present null plot at the right hand edge, so comments in earlier post applies. The N/A plot is double what it would be for a plot of the equivalent CMA channel due to the fact that 2 MAs are used in this one, one with double the length. Therefore plot in conjunction with channel. You can also create a similar indicator with Simple MAs and overlay that (I plot the Triangular version as a bold line and the Simple as a light one)…this has less N/A plot as it doesn’t need the 1.5 factor but is consequently more erratic due to less smoothing. Gives you a bit more info though.
This one is a case of swings and roundabouts really…just another way of looking at what a CMA is telling you, but I find it visually very useful for determining if there is a strong cyclic component and what the average wavelength of it is. Allows me to define time periods when I should be looking for cycle tops and bottoms to occur if the symmetry holds up. Or, put another way, gives me an idea of when I should *not* be looking for tops/bottoms, which is equally as important!
Bear in mind of course that there is variation in wavelength all the time, so don’t try banging your head against it trying to get a smooth plot like a sine wave…that would be far too easy!!
Anyway, what the attached plot of GBP/USD spot is telling me now is that we may be approaching a cyclical top this week as shown by the grey cycle line. However…the longer-term green cycle has only just bottomed. Conclusion – take some long profits first and then secondly take the rest & go short if a set-up shows itself with confirmation on shorter time frames… but do so with care and stay alert for possibility of up-trend re-establishing until end Jan/early Feb (when green cycle estimated to top).
Note… there is more to my trading strategy than this and so this is NOT a trade recommendation!!!...just showing you the line of thinking that goes with these particular indicators.

PS, don’t ask me how I got the buy/sell arrows on the plot please…I won’t tell !!

Grazie Arosa...apprezzo tantissimissimo!
alcune le avevo trovate anch'io di quelle che hai riportato. La più interessante è l'ultima che è il calcolo di un indicatore di ciclo di Hurst (differenza tra due medie mobili centrate)...provo a scremare ciò che mi interessa da quest'ultimo listato.
Spero di poter contraccambiare quando avrai bisogno tu.
