LRCChannelParams

Calculates Linear Regression Channel parameters.

Syntax

LRCChannelParams(
    shift: number,
    period: number,
    priceType: TPriceType
): { StartValue: number; EndValue: number; Height: number; Top: number; Bottom: number }

Parameters

Parameter	Type	Description
shift	number	Starting bar index for calculation
period	number	Number of bars to calculate over
priceType	TPriceType	Type of price to use (Open, High, Low, Close, etc.)

Return Value

Returns an object with the following properties:

• StartValue: number - Starting value of the regression line

• EndValue: number - Ending value of the regression line

• Height: number - Channel height (maximum deviation from regression line)

• Top: number - Upper channel line value

• Bottom: number - Lower channel line value

Description

The LRCChannelParams method calculates parameters for a Linear Regression Channel. This includes:

1. The regression line (middle line)

2. Channel height based on maximum deviation

3. Upper and lower channel lines

The Linear Regression Channel is a technical analysis tool that combines linear regression with channel lines to show the trend direction and potential support/resistance levels.

Available Price Types can be found in the TPriceType section.

Example

// Calculate LRC parameters for last 20 bars
const lrcParams = this.api.LRCChannelParams(0, 20, TPriceType.CLOSE);
console.log("Linear Regression Channel Parameters:");
console.log(`Start Value: ${lrcParams.StartValue}`);
console.log(`End Value: ${lrcParams.EndValue}`);
console.log(`Channel Height: ${lrcParams.Height}`);
console.log(`Top Channel: ${lrcParams.Top}`);
console.log(`Bottom Channel: ${lrcParams.Bottom}`);

// Use LRC for trend analysis
const currentLRC = this.api.LRCChannelParams(0, 20, TPriceType.CLOSE);
const previousLRC = this.api.LRCChannelParams(1, 20, TPriceType.CLOSE);

const trendUp = currentLRC.EndValue > previousLRC.EndValue;
console.log(`Trend direction: ${trendUp ? "Up" : "Down"}`);

// Check for price position within channel
const currentPrice = this.api.Close(0);
if (currentPrice > currentLRC.Top) {
  console.log("Price above channel - potential overbought");
} else if (currentPrice < currentLRC.Bottom) {
  console.log("Price below channel - potential oversold");
} else {
  console.log("Price within channel");
}

// Calculate channel width percentage
const channelWidth =
  ((currentLRC.Top - currentLRC.Bottom) / currentLRC.EndValue) * 100;
console.log(`Channel width: ${channelWidth.toFixed(2)}%`);
