This is a function that you can use in strategies. Not a strategy in and of itself. Example thumbnail is showing the function applied to a strategy. Oftentimes, I am asked a question regarding how to hold a variable at a specific, constant level over a conditional period of time. This question is always asked in a very long convoluted way like "I want the...

Hi fellow traders.. Happy to share a Linear Regression & RSI Multi-Function Custom Screener with Table-Labels... The Screener scans for Linear Regression 2-SD Breakouts and RSI OB/OS levels for the coded tickers and gives Summary alerts Uses Tables (dynamica resizing) for the scanner output instead of standard labels! This Screener cum indicator collection has...
