QQQ overlay over NQ/NDX

746
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!
Release Notes
show 9 levels by default
Release Notes
Anchor label at the end of the line properly.
Release Notes
By default calculations happen at the end of candle close (can switch to per ticks)
Removed the ticker restriction.
Release Notes
custom color/line options for lines and labels.
Release Notes
Improvements to lines, colors.
Option to freeze the ratio to RTH close (for after hours)
Support only QQQ to be drawn over other tickers. (base use case).
Release Notes
Show proper symbol for NQ quarterlies. Also cache previous RTH session ratios to show correct numbers when the market is open. (avoid staleness).

Still wait for one candle close to get accurate mapping when RTH opens.
Release Notes
By default, "Lock to the previous RTH ratio". This fixes issue reported by @archdesign75. Thank you archdesign75
Release Notes
Make more QQQ levels visible by default. Raise it from 9 levels to 21 levels. Thank you airjunkies2000
Release Notes
increased the number of default levels shown. (also dropped the NQ mapping at the level, as it is kinda redundant).
Release Notes
changing the default levels 51 (25*2 +1 ). High volatility days exceed the levels typically shown.
Release Notes
Users do not need to use ration mode. During after hours, it is locked to previous QQQ close, and during the active market, calculation is done actively.
Release Notes
change the efficiency strategy.
- instead of deleting and re-drawing, we cache the lines and move
- lines re-drawn only after NQ moves by 3 pts. (user adjustable).
Release Notes
when pre-market is open, auto switch to live mode. Prev version was waiting for NY open.
Release Notes
changed the default line color. Update bars/labels once price moves to 5pts. 1pt move is still jittery.
