OPEN-SOURCE SCRIPT
Updated QQQ overlay over NQ/NDX

This enhanced version of the QQQ overlay script builds on the original by © PtGambler, adding smoothing via stepped ratios updated on candle close to eliminate oscillation, optimizing performance by reusing lines/labels, restricting visibility to relevant symbols (NDX, NQ1!, NAS100USD), and improving visuals with rounded levels, adjustable level counts (default 5 total), extended lines, and label styles matching "Key Levels" indicator for better readability (gray text, transparent background). Removed unnecessary table and floating labels for a cleaner chart. Thanks to © PtGambler for the foundational work!
