Anand Bollinger Bands - Linear Regression Slope

Summary

Bollinger Bands show price volatility using SMA ± standard deviation
Linear Regression calculates the mathematical trend through the middle line
Slope comparison (current vs. previous) determines if trend is rising or falling
Color changes based on that trend: Green = up, Red = down
Uses same period for both BB and slope = everything stays synchronized

The result: A visual indicator that shows you not just where price is relative to volatility, but also which direction the trend is actually moving!
