Industry Group Strength (Custom ETFs)

This script is a modified version of the 'Industry Group Strength' indicator. It enhances the 'Investment Trusts/Mutual Funds' category by incorporating a curated list of key Sector and Thematic ETFs (e.g., SMH, XBI, BLOK) for top-down market analysis. This allows traders to track broad sector rotation while retaining the original functionality of ranking individual stocks within their specific industries based on Relative Strength.
