Regression Slope Shift

Normalized Regression Slope Shift + Dynamic Histogram

This indicator detects subtle shifts in price momentum using a rolling linear regression approach. It calculates the slope of a linear regression line for each bar over a specified lookback period, then measures how that slope changes from bar to bar.

Both the slope and its change (delta) are normalized to a -1 to 1 scale for consistent visual interpretation across assets and timeframes. A signal line (EMA) is applied to the slope delta to help identify turning points and crossovers.

Key features:

- Normalized slope and slope change lines

- Dynamic histogram of slope delta with transparency based on magnitude

- Customizable colors for all visual elements

- Signal line for crossover-based momentum shifts

This tool helps traders anticipate trend acceleration or weakening before traditional momentum indicators react, making it useful for early trend detection, divergence spotting, and confirmation signals.
