The Linear Regression Angle measures the angle of the trend line calculated using linear regression over a selected number of periods. It helps determine how steeply the price is trending upward or downward.

For automated trading strategies, this indicator helps identify whether the market is trending strongly, weakly, or moving sideways, based on the slope angle of the price trend.

What does the Linear Regression Angle measure?

The Linear Regression Angle calculates the angle of the regression line fitted to recent price data. This line represents the best-fit trend across the selected period.

In general:

• A positive angle indicates an upward trend
• A negative angle indicates a downward trend
• An angle near zero indicates a sideways or weak trend

The steeper the angle, the stronger the directional trend.

This makes the indicator useful for measuring how strongly price is trending rather than simply identifying direction.

How the Linear Regression Angle is used in indicator-based triggers

In automation, the Linear Regression Angle can be used to detect changes in trend direction or trend strength.

For example, strategies may monitor when:

• The angle crosses above a defined value, suggesting a strengthening upward trend
• The angle falls below a defined value, indicating increasing downward momentum
• The angle moves relative to another indicator, helping confirm whether a trend is gaining or losing strength

These types of triggers allow automated strategies to react when price begins trending more strongly in a specific direction.
