Linear Regression - Reverse Up/Down Strategy

For my first foray into pine script I took the code from the generic "Consecutive up/down" and flipped the logic. I added a linear regression filter to try and stay with the overall trend. ATR added for visual, I eventually want to use it as part of the money management.


Rules to open trade or close the opposite:
IF the linear regression slope is >=0 AND the last candle closes lower, BUY
IF the linear regression slope is <=0 AND the last candle closes higher SELL

Rules to close the opposite:
IF the linear regression slope is >=0 AND the last candle closes higher, close any open SELL
IF the linear regression slope is <=0 AND the last candle closes lower, close any open BUY

Nota Keluaran:

Go with or against the Linear Regression trend using pullbacks or looking for breakouts of consecutive bars.

Updated smooth moving average for ATR channel

Added a date range function for choosing which date to test.
