# Regression Channel

The Regression Channel is an analytical drawing tool used to precisely define a price trend and its boundaries with regard to the support and resistance levels.

## Understanding Regression Channel

To create the Regression Channel two parallel equidistant lines are drawn above and below a linear regression regression channel that is based on a user specified price (High, Low, Open, Close). The bottom line is the support level, and the top line - the resistance level. All these channels are based on the linear regression regression channel.

Prices may extend outside the channel for a short period of time. But if prices stay outside the Regression Channel for a long period of time, a reversal trend may occur.

The distance of the channel lines from the median regression line is based on either:

- The highest point among the peaks and lowest point among the troughs between the points upon which the median regression line is drawn.
- A user specified number of standard deviations above/below the median regression line.
- The maximal upward or downward oscillation.
- A user specified number of standard errors above/below the median regression line.

Markets tend to have a "balancing point" that is a point towards which prices tend to move. The Regression analysis allows you to determine this "balancing point". On the other hand, the Standard Error analysis helps determine the "extreme points".

In MultiCharts there are 4 types of regression channels:

- Segment High-Low
- Standard Deviation
- Raff Regression
- Standard Error

## Inserting Regression Channel

- Select one of three ways to insert the Regression Channel:
- In the menu select
**Insert**, point to**Drawing**and click**Regression Channel**. - Click the
**Regression channel**icon on the**Drawing**toolbar. - Click the arrow next to the
**Drawing tools**icon on the**Main**toolbar and select**Regression Channel**from the menu.

- In the menu select
- The cursor will change to the
**Regression channel**. - In the Chart Area click where the Regression Channel is to begin.
- Then keeping the left mouse button pressed move the pointer left or right to position the Regression Channel.
- Release the button.

## Moving Regression Channel

To move a Regression Channel without changing its period length:

- Point the cursor at the Regression Channel that is to be moved.
- The cursor
**Pointer**will change into**Hand**. - Then keeping the left mouse button pressed drag the drawing tool to the desired position.
- Release the button.

## Reshaping Regression Channel

To reshape a Regression Channel (change its length):

- Point the cursor at the Regression Channel that is to be reshaped.
- The cursor
**Pointer**will change into**Hand**. - Left-click the Regression Channel and 2 small squares will appear at both ends of the regression line.
- Drag one of these squares till the drawing tool becomes of the desired shape. Keep in mind that the Regression Channel will dynamically calculate the regression.
- Release the button.

## Formatting Regression Channel

In MultiCharts one can change the settings of the Regression Channel. All the changes are performed in the **Format Regression Channel** window.

Each instance of a Regression channel has its own **Format** window. The number (if there are 2 or more Regression channels in the same Chart Window) are shown in the titlebar of each **Format Regression Channel** window.

One can change the settings of a Regression Channel: the color, style and weight of the Regression, Upper Channel and Lower Channel lines. It is possible to extend the Regression Channel to the left or/and to the right. One can choose to show or not the labels and select their font, its style and size, and the character set. It is possible to apply the strikeout or underline effects. If shown the labels can be displayed to the left or to the right of the Upper Channel and Lower Channel lines. One can also select one of 4 calculation types available to compute the Regression Channel and the price types to compute the regression line. It is also possible to change the time coordinates of the Regression Channel.
