Creating a Regression Channel

[mrlogik]

Hello,

I am working on creating a regression channel using the DrawRegressionChannel() function built into NT.

Is it possible using this function to set some sort of Regression Factor to change the width of the channel?

Thanks.

DrawRegressionChannel() does not return any values you can use. RegressionChannel() is the indicator you should call to get values for the channel.

Thanks for the reply Josh. I'll look into that.

Hey Josh.

Using DrawRegressionChannel() does not input a width for the number of stand devs, yet RegressionChannel() does not have this input. My code is as such.

DrawRegressionChannel(    CurrentBar.ToString(), false, 0, bSinceLineUp, 
                                            Color.White, DashStyle.Solid, 1, 
                                            Color.White, DashStyle.Dash, 1, 
                                            Color.White, DashStyle.Solid, 1);

Where bSinceLineUp is the number of bars used for the calculation.

How can I get the Upper / Lower channel values using RegressionChannel() indicator call if to .Upper / .Lower if RegressionChannel() uses requires a width input, but the DrawRegressionChannel() does not. Does DrawRegressionChannel() have a default value of width of 1?

Thanks for your help.

Hi,

Not sure I follow. The Regression Channel indicator does have a width input.

RegressionChannel(int period, int width)[int barsAgo]

I guess I'm not sure what you are asking.

Hey Josh.

I'm plotting right now using the DrawRegressionChannel() as i posted previously. This function does not have a width input.

I want to reference the Upper / Lower channel lines of this. I understand (or I think I understand) that I can use the RegressionChannel() call to find the Upper / Lower channel lines using the same period I used for DrawRegressionChannel, then referencing the .Upper / .Lower variables from RegressionChannel(). If this is true, what would I have to set the width input for RegressionChannel() to, to have the same channel.

Basically what I'm asking is how can I create the same channel using both
DrawRegressionChannel and RegressionChannel?

Thanks again

Ok. I see what you mean. The width drawn by the regression channel draw object is determined by the setting you have set for the draw object's default. Double click on the draw object to bring up the properties window. Default is 2 std devs.

[mrlogik]

Yes, that is what I was looking for.

Thanks.

IRegressionChannel, DrawRegressionChannel, RegressionChannel relationship...

I understand.

RegressionChannel width for Midpoint

So I get that you can do:

IRegressionChannel rchannel = DrawRegressionChannel("rchannel_", Bars.BarsSinceSession, 0, Color.Blue);

and what gets created is a Regression Channel that utilizes the default settings in the actual RegressionChannel indicator(in this case "2");

// lower
RegressionChannel(rchannel.StartBarsAgo, rchannel.StdDevLower).Lower[0];

// upper
RegressionChannel(rchannel.StartBarsAgo, rchannel.StdDevUpper).Upper[0];

// midpoint
RegressionChannel(rchannel.StartBarsAgo, ??); what does midpoint use as a width?

Do all 3 lines use the same width? In the case 2, 2, 2 for Upper, Lower and Midpoint?
In this example the rchannel object only has the upper and lower values exposed.

Hello funk101,

Thank you for your post.

If you are just calling their value, they have no width. If you are adding them to the chart via Add() then they will use the default settings.

[funk101]

If I remove the width as in:

// midpoint
RegressionChannel(rchannel.StartBarsAgo)[0];



It throws an error: "No overload method for RegressionChannel takes 1 arguments"

Hello funk101,

Thank you for your response.

The width parameter is the number of std deviations to calculate the channel lines. This is a user configured setting, but if you are trying to use the same values as if you were calling them from the same instance of the indicator, then they would use the same value.

[funk101]

So, since my default is "2" then I would use 2 for mid, lower, and upper, correct?

// lower
RegressionChannel(rchannel.StartBarsAgo, 2).Lower[0];

// upper
RegressionChannel(rchannel.StartBarsAgo,2).Upper[0];

// midpoint
RegressionChannel(rchannel.StartBarsAgo, 2);

Hello Funk101,

That is correct.
