to mathematicians... laguerre indicator question

Hi All,

I have a question related to laguerre indicator ... as you all know that moving average say period 50 at 1H time frame is not the same period at 30M...

I believe you know that it must be converted to get the right period using this equation = period *(main TF/ new TF) so we get it like this= 50*(1H/1/2Hour) ==> 50*2 = 100

so the 50 moving average at 1H time frame is the same as 100 moving average at 30 minutes....

Now my question is, what about laguerre indicator??? do we have to convert gamma parameter?? what about the MA period??

any comments are appreciated....

Is it possible that none knows about this !!!

I thought the forum is full of high degree or well educated people...

please traders share you opinions,

I have no university degree but I'll attempt to answer.

You need to think about both the formula and the data used to construct the indicator. To use your example, a SMA(100) on the M30 chart is averaging M30 closes, while a SMA(50) on the H1 chart is averaging H1 closes. Hence they will likely produce very similar curves, whose difference is due to any 'outlying' closes on the intervening M30 candles. With an EMA, each value is weighted more heavily toward the more recent values....... and so on.

I've never heard of the laguerre indicator. If you post either the formula, or the source code, I'll look at it for you.

I found a Laguerre indy in my archive (attached). It doesn't have a MA period, only a gamma value, so I'm not sure if it's the same one you're talking about.

The screenshot shows curves plotted for gamma = 0.5 (magenta), 0.6 (blue), 0.7 (red), 0.8 (green). All on a H1 chart. I'm unsure what the different gamma values mean.

Also found some Laguerre math here and here. The math certainly ain't trivial, at least by my standards; guess I should have paid more attention in calculus class. And I don't know if or how this math relates to the indy that I posted.

Then I found here that the Emerald King version (that I posted) is apparently differs from John Ehlers' original formula. There are a lot more Laguerre indys in the thread --- take your pick!

It's possible to create a MTF version of any indy without understanding the math, if that's what you're seeking**. It's simply a case of remapping the indy values from the parent TF to the TF of the current chart. [EDIT] Looking at the attached indy's formula, it's fairly obvious that doubling the gamma value is invalid as a way of shifting from a H1 to M30 TF. A gamma value of 1 produces no plot, and a value > 1 a qualitatively different curve to those where 0.5 < gamma < 1.

Sorry that I can't help you further. If nobody else here is able to help, you could try posting on the forex-tsd forum.

**[EDIT] Just found a MTF Laguerre here. Haven't tested it, but hope it helps you.

Hi hanover,

Good day,

Thanks a lot for the valuable information... I actually made a mistake thinking that the Laguerre indicator is based on MA, but it turned out to be on some high level of math...

In fact it is an interesting indicator, and I just wanted to know more about it since I like to understand what an indicator does on the chart even I know that all indicators are actually useless, and of course I don't mean fibonaccie by that...

Thanks again for the great effort, mate... If I find something good about, I will post here so traders get the advantage of that,

Best wishes,
