Linear Regression Formula Scraped Calculation With Alerts

Here is the Linear Regression Script For traders Who love rich features

Features ++ Multi time frame -> Source Regression from a different Chart ++ Customized Colors -> This includes the pine lines ++ Smoothing -> Allow Filtered Regression; Note: Using 1 Defaults to the original line. The default is 1 ++ Alerts On Channel/Range Crossing

Usage ++ Use this for BreakOuts and Reversals ++ This Script is not to be used Independently

Risks Please note, this script is the likes of Bollinger bands and poses a risk of falling in a trend range. Signals may Keep running on the same direction while the market is reversing.
