What is Regression Trend Reversal Signals & Forecasts?
Regression Trend Reversal Signals & Forecasts combines multiple regression methods into a single trend and reversal framework. It allows traders to choose between Linear Regression, Theil-Sen Regression, LOESS smoothing, Nadaraya-Watson smoothing, Polynomial Regression, and a Kalman Filter to estimate the underlying price path.
The selected regression line acts as the center of a dynamic channel. The channel width is based on the standard deviation of the distance between price and the regression line, allowing it to adapt to changing market conditions.
The script also identifies potential reversal conditions when price extends beyond the channel and then shows signs of rejection. In addition, it can project the current regression slope forward to provide a simple forecast of the current trend path.
Regression Trend Reversal Signals & Forecasts Features
Regression Channel
Dynamic bands expand and contract based on how far price deviates from the regression line.
TradingView Snapshot
Trend Flip Signals
Generates directional markers when the regression trend changes from rising to falling or from falling to rising.
TradingView Snapshot
Reversal Signals
Marks potential bullish and bearish reversals when price extends beyond the channel and begins rejecting those extremes.
TradingView Snapshot
Forecast Projection
Extends the current regression slope into future bars and optionally displays projected channel boundaries.

How Regression Trend Reversal Signals & Forecasts Works
• Regression Line — A statistical estimate of the underlying price trend. Different methods can be selected, ranging from straight-line regressions to adaptive smoothing techniques.
• Theil-Sen Regression — A robust regression method that uses median slopes from all point pairs, reducing the influence of outlier price spikes.
• LOESS Regression — A locally weighted regression that fits nearby observations more heavily than distant observations to create a smooth trend curve.
• Nadaraya-Watson Smoothing — A kernel-weighted averaging method that estimates trend by assigning larger weights to recent observations.
• Kalman Filter — A recursive estimation method that continuously updates the trend estimate as new prices arrive.
• Polynomial Regression — A curved regression model that can capture non-linear trend structures using higher-order polynomial functions.
• Regression Deviation Bands — Channel boundaries calculated from the standard deviation of price relative to the regression line.
• Regression Slope — The rate of change of the regression estimate used to determine trend direction and forecast projections.
How to Use Regression Trend Reversal Signals & Forecasts
• Select a regression method that matches the market behavior you want to analyze. Linear and Theil-Sen are suited to directional trends, while LOESS, Nadaraya-Watson, and Kalman provide smoother adaptive estimates.
• Use the regression line as the primary trend reference. Rising regression values indicate strengthening conditions, while falling values indicate weakening conditions.
• Monitor the channel boundaries for extended price movement away from the regression estimate.
• Watch for bullish reversal markers below the lower band after downside extensions and bearish reversal markers above the upper band after upside extensions.
• Use trend flip signals as confirmation that the regression slope has changed direction.
• Compare price location within the channel to gauge whether price is trading near trend equilibrium or at an extreme deviation.
• Use the forecast projection as a continuation estimate of the current regression slope rather than a prediction of future market behavior.
