Median = LinearReg((Open+High+Low+(2*Close))/5); Deviation = StandardDev(Median);
Top Band = Median + MultiplierDeviation; Bottom Band = Median -MultiplierDeviation;
if Median[period]<Top[period-1] and Median[period] > Bottom[period-1] then DEV[period]= DEV[period-1]; Top[period] = Top[period-1]; Bottom[period] =Bottom[period-1]; Median[period]= Median[period-1]; end
The indicator was revised and updated

Hello Apprentice,
thank you for your reply. But to see your attachment picture this is not the same. Look my attachment and you can have informations about this indicator here : http://www.mogalef.com
Recall of the code in pro Realtime language :
CP=(open+high+low+2*close)/5
F=LinearRegression[3](CP)
E=std[7](F)
if barindex<8 then
Mediane = undefined
BandeHaute = undefined
BandeBasse = undefined
Else
BandeHaute = F+(E*2)
BandeBasse = F-(E*2)
if F<BandeHaute[1] and F>BandeBasse[1] then
E=E[1]
BandeHaute=BandeHaute[1]
BandeBasse=BandeBasse[1]
endif
Mediane =(BandeHaute+BandeBasse)/2
Endif
return BandeHaute coloured (255,154,51) as"Mogalef Bande Haute", Mediane coloured (102,0,204) as "Mogalef Mediane", BandeBasse coloured (0,204,255) as "Mogalef Bande Basse"

Thanks for the warning. Corrected.

Thank you very much for you’re reactivity. It seems to be near Mogalef bands but without the same reactivity the gap of the bands is later in you code than this of prorealtime code Look the comparaison of the two graphics EURUSD in Daily

The problem is that I got Partial and three of four different formulas for this indicator. So I’m not sure that it the right one.
Re: Mogalef Bands
Terminus · Tue May 24, 2011 10:08 am
ok , i understand you because the divulgation of this code is very recent. I know that the ProRealtime code i give you has been validate by Eric Lefort (one of the the authors)
Maby the problem is her (traduction): “C’est bien la régression linéaire du cours pondéré qui est prise en compte dans la cassure des bandes, et non pas le cours pondéré lui-même. “ “It is good the linear regression of the balanced course(price) which is taken into account in the break of bands(strips), and not the balanced course(price) itself. “
if t-you speak french you have a lot of informations in the web site www/.pro-at.com you
HERE i find the code by the autor (Reference version for free distribution):

Re: Mogalef Bands
Blackcat2 · Tue May 24, 2011 8:31 pm
This is an interesting indicator… I’m currently testing this..
How many % identical compared to the original / intended code?
Can I please have the option to change line width and style?
Thanks.. BC

Hello Aprentice,
have you seen my new post with the code source based of the author for the mogalef Bands? Are you understand it .(FutureStation Nano WHSelfinvest language) Is it different of the proRealtime version who had problem with a candle delay ? Tanks for your answer.
Re: Mogalef Bands
Apprentice · Wed May 25, 2011 1:14 pm
To Terminus Can you please test this version. The strange thing, I got this result using a completely different algorithm.

Apprentice,
in fact there is a problem with the last “mogalef.lua” that you maked,it doesn’t work When i try to charge it on the station i have an error message . Detail of the error ( image on attachment) : String “Mogalef.lua” : 98’)’ exepted near’period’
(When i charge it on the plaform i forgeted to actualise and in fact i use the old vesion …)
Re: Mogalef Bands
Terminus · Thu May 26, 2011 4:16 am
Sorry i try again to put in the station the new indicator and now it’s ok. we get closer to a clean version but there are still problems I noted the differences on the attached image
Re: Mogalef Bands
Terminus · Fri May 27, 2011 5:01 am
after testing it sounds ok on small units of time but there is a problem from the 30mn Perhaps a story of GAP ….
Many thanks for your work Apprentice

Hi Apprentice
I’m sorry for being late (I’m working for the moment) : thank you very much for this indicator and your work It’s great
and thanks Terminus

If these Mogalef Bands work on the basis of standard deviations away from the median regression line, what is the difference between these and Bollinger bands?
Re: Mogalef Bands
Terminus · Tue Aug 16, 2011 3:52 pm
Put the two indicators on one screen and you can see the difference. this two different vison of a range.

Hi, I don’t know whether this code was already part of the thread, but I found it published on a french forum. There are two files, one is concerning linear regression and the other file is the mogalef bands. Not too much french involved but if needed ask for help.
