Linear Regression Channel (Simple)

Linear Regression Line is a straight line that best fits the prices between a starting price point and an ending price point.

The indicator has two channel modes 1) Max Distance The distance between Linear Regression Line and Linear Regression channel, equals to the value of maximum close price Distance from the regression line.

2)Standard deviations Default value is one Standard deviations from central line.

Linear Regression Channel.lua

Data Filter version. If the price is, beyond the default standard deviation, price is set to standard deviation. if Price >Mid Line + STDMultiplier then Price = Mid Line + STDMultiplier elseif Price < Mid Line - STDMultiplier then Price = Mid Line - STDMultiplier end

hi all!

Could you please take a look at auto fibonacci lines indicator. If the approach to manage lines in auto fib. indicator is ok, I can rewrite channel indicator, so you will be able to choose the from/to bar to calculate the channel. I think it would be a bit more useful.

Is it possible to add in a tidbit of code in order to have the channel extend further than the current period? I suppose a toggle would be handy for those that did not want it…

Thanks!

Linear regression channel is made as an instrument in upcoming version of TS/Marketscope. So, just wait a few days to have these features “natively”.

Very nice indicator, I agree with zekelogan about the option to extend the line couple of bars and also to adjust line style…

Cheers.. BC

I find the regression channel tool in the new version of marketscope difficult to use. I still use this indicator as it automatically update abd calculate the channels.. Is it possible to ask for option to change line style?

Thanks

where can i find the linear regression channel so i can set it to 2 deviation? Because the standard one doesnt tell you what deviation it is set on. Thank you Holly

Under the standard, do you think about the standard tools within the Platform.

This indicator, posted hire, i do not use a standard deviation. But it is possible to add it.


Re: Linear Regression Channel (Simple)

Standard deviation, channel mode added.

Is it possible to refine this in such a way that outliers in the data set are ignored? For example , if the linear regression channel is based on a user defined 20 candles, but one of those candles sees an uncharacteristic spike in volatility that is completely out of line with all other candles then it should be removed from the data set used to calculate the linear regression channel and so only 19 periods will be used for the calculation in that case. Outliers may be removed from the dataset if perhaps they exceed 1.65 Standard Deviations or 2 standard deviations from other candles in the defined set.

Very interesting proposal. I’ll try to write it as soon as possible.

In addition, I’ll try to write a Price / Data filters in order to filter the different data sources. What would later be used with existing indicators.


Re: Linear Regression Channel (Simple)

Apprentice · Wed Feb 16, 2011 1:57 pm

I add a version that contains a simple data filter.

if open[i] > Mid[i]+ SD[i] then open[i] = Mid[i]+ SD[i]; elseif open[i] < Mid[i] - SD[i] then open[i] = Mid[i] - SD[i] ; end

if close[i] > Mid[i]+ SD[i] then close[i] = Mid[i]+ SD[i]; elseif close[i] < Mid[i] - SD[i] then close[i] = Mid[i] - SD[i]; end

if high[i] > Mid[i]+ SD[i] then high[i] = Mid[i]+ SD[i]; elseif high[i] < Mid[i] - SD[i] then high[i] = Mid[i] - SD[i]; end

if low[i] > Mid[i]+ SD[i] then low[i] = Mid[i]+ SD[i]; elseif low[i] < Mid[i] - SD[i] then low[i] = Mid[i] - SD[i] ; end

After thorough research plans to release an independent data filter.

UPDATE REQUEST

Would it be possible to have this indicator working on a basis where it doesn’t include the current candle (so a linear regression channel based on candles n-x to n-1) and then incorporate a breakout strategy on this indicator so that if the current candle (not included in the regression calculation) breaks out of either the upper or lower limit then a trade is entered?


Re: Linear Regression Channel (Simple)

Can we please request an update to this indicator which would add user option of additional standard deviation parameters such as 0.25, 0.50, 0.75, 1.618, 2.0, 3.0.

thanks,

sjc


Re: Linear Regression Channel (Simple)

Version with Multiple, deviation lines added.


Re: Linear Regression Channel (Simple)

Coondawg71 · Mon Dec 10, 2012 6:55 am

Thanks! Exactly what I needed. Works great for trading off the median lines and the trend lines associated with it. As you probably know, there is the small issue of: if you toggle any of the additional ratios to “OFF” it creates an error for the indicator. So before users flood the thread with error notices, users please toggle all the default ratios to “YES”, and the “Channel Mode to “Deviation”; these ratios will prove to be quite beneficial trend lines for future price action!

Thanks Again for another job well done and expeditious turn around!

Corrected. By mistake I upload wrong, in development version.

This is exactly what I also wanted, I think I managed to make it work. Keep in mind the following: For a 2 candle period, lets consider the last 4 candles: n is the current (still running) one: the lines are drawn up to this candle so you see if there will be a break out or not; it is not taken into account for the calculations though n-1 and n-2: these are the candles used for the calculations n-3: the line is also drawn till that but it is not taken into account for the calculations; I could not remove it so I just kept it and just ignore it.

I have also added two output streams, one for tilt and one for break out: tilt: -1 for downslope, 0 for horizontal, 1 for upslope break out: 1 for breaking top line, -1 for breaking bottom line, 0 for not breaking either

When the current candle closes, keep in mind that:

Apprentice one question for you: I tried to use internal streams (addInternalStream) for passing values to a strategy but I failed; is it only possible with normal streams (addStream) ?


Re: Linear Regression Channel (Simple)

boss_hogg · Tue Jan 08, 2013 1:01 pm

One more thing, if there are two ore more consecutive break outs in the same direction, then break out value is 2 or -2 for top/bottom respectively.


Re: Linear Regression Channel (Simple)

Apprentice · Wed Jan 09, 2013 5:06 pm

Yes you have to use normal streams.

Try to use this implementation.

indicator.parameters:addBoolean(“Use”, “Use Signal Mode”, “” , true);

local Use; local Out;

Use =instance.parameters.Use;

if Use then Out = instance:addStream(“Out”, core.Line, name, “Out”,core.rgb(0,0,0), first); end

if Use then if condition then Out[period]= 1; elseif condition then Out[period]= -1; end end

By adding this Additional parameter, Use. You can control the output signal. If u use it as indicator, set it to false. If called from the strategy Use true.
