Hello!!! I'm Cristina. I'm from Italy and I'm looking for help to realise a formula. First I'm sorry for my bad english and my bad practise in efs

I'm trying to build a cyclical indicator based on two centered moving averages = CMA and its speed

First I created a given CMA of the cycle under consideration. then I calculated the difference with the CMA of double length, like a Price oscillator of two CMA.This difference is my cycle indicator=C
Ex:cma(32)-cma(64)=C

This is C for a weekly cycle http://i55.tinypic.com/2z9gxew.jpg

Now I want to get the speed =V of indicator C making the difference between a given value and the previous one and so on: that is V=C(t)-C(t-1)
After obtaining V , I need to put the zero axis and a simple moving average of V

When V cuts down to the top the axis of zero or the SMA, the cycle in question is likely to have its maximum size and will be entered in its descending phase of closure. Similarly, when V will cut from the bottom its SMA or the axis of zero we have the start of the cycle.

Until now we have created the cyclical indicator C and I attach the script. We are not able to finish the part of the formula to calculate speed= V and the last following steps.

is there someone who would like to help us to finish our speed indicator please? Thank you very much

Have a nice weekend

Cristina

Re: Re: Help: cycle indicator

With the help of mr Ashish from Esignal in london we have achieved most of the indicator. now only miss the last part. I hope someone can help me toget to the finish.

You can find here the EFS CMA_OSC: http://share.esignal.com/ContentRoot...Oscillator.efs
This can be a very useful tool for identifying a cycle of prices as well as from the studies of Hurst. It 's based on the difference between two centered moving average.

Now we need to do the last step: We need to have the CMA OSC that arrives to "today" otherwise it is useful only for analyse "the past" and not "the present" and "the future". Ok. how can we do? if the CMA is shifted of 10 bars we must add at the last true bar of the prices, 10 "false bars" (and as we can't guess the future, we must use 10 false bar equal to the last one). I show you a graph: http://i52.tinypic.com/2iiwx1u.png

Now I don't know if it's possible do this with javascript. I'm sure you can do this with excel and I attach you an example: http://i51.tinypic.com/303jr4n.png

I really hope someone can help me
