Triple RAFF Channel projection (On Price)

Triple Raff Channel linear projection indicator for PRT.

Premise

PRT implementation of the “Bianca” trends visualization of 3 linear regressions. This indicator adopts the Raff channel algorithm and outputs 3 sets of support and resistance lines on the same chart. These sets represent:

Primary trend (blue)
Secondary trend (green)
Tertiary trend (red)

Interpretation:

If all three sets of trend-lines align, a strong sentiment is established. This could be bullish, bearish or consolidating.

If tertiary trend and/or secondary trend are diverging from primary trend, or diverging from each other, a breakout of the wider trend is more probable.

If you are not familiar with this concept and associated trading systems, read up on raf channels and/or bianca trends.
http://stockcharts.com/school/doku.php?id=chart_school:chart_analysis:raff_regression_chan

Variables

Defaults are 50 bars (primary); 20 (secondary); 10 (tertiary). These can be changed by you.

Developer Information

The mid lines are not plotted but they are available of course. If you would like to view them or adapt further then use reg
Support and resistance lines are averaged from raff and riff lines. If you want to see both, replace averaging code (source code is commented)

Enjoy!

than you

shephinc • 02/10/2017 #
Is there an easy way get a value returned from the indicator that says if the blue channel is heading up or down ?

alf • 02/10/2017 #
Hello,
How can i project it on the chart?
Now it is below amongst the other indicators..
Thankss:)

lebrinque • 02/10/2017 #
This is AWESOME!

Thank you Maz!!
- Maz • 02/10/2017 #
  You’re welcome, thanks

lebrinque • 02/10/2017 #
Does anyone know how to make the lines extended? Like having an option for right and left?

Maz • 02/10/2017 #
With PRT it’s not currently possible to extend lines into the future (right) via the scripting language

Kris75 • 02/10/2017 #
Hi Maz,
How could we translate this in a strategy?

Kris75 • 02/10/2017 #
fantastic job btw

ggolfet • 02/10/2017 #
it seems it’s not working anymore with prorealtime 11, anyone has the same problem?

Moritz Müller • 02/10/2017 #
hi there,
I just checked and I does not work for me anymore neither – unfortunately. would be great if somebody could point to the right direction how to adjust the code.
Would be great if the code could be adjusted to work as a screener as well – as shephinc mentioned.
thanks
- jums • 02/10/2017 #
  Hi,
  
  Can you make an update for PRT v11 ?
  
  Best Regards,

Lotech123 • 02/10/2017 #
PLEASE, PLEASE someone modify the code of this special indicator for V 11.
Thank you in keen anticipation
- Nicolas • 02/10/2017 #
  just use 3 times a linear regression channel code you will find in the library.

Maz • 02/10/2017 #
Hi all, firstly happy to know that this is helping you. I look into updating it for PRT11 when I get the chance. All the best
