Vitali Apirine proposed a new idea named "The Linear Regression-Adjusted Exponential Moving Average". Here it is the pine v4 impelementation of this idea.
Function
Linear Regression Adjusted Exponential Moving Average (LRAdj EMA) is used to combine a linear regression (linreg in tradingview) with an EMA. It can be used to define the trend reveral points while filtering price action. The LRAdj EMA can be used in combination with a traditional EMA of the same length to facilitate trend identification or it can serve as an important MA candicate in a trading system to potentially replace T3, JMA, KAMA or other MA functions.
