Overview
Dark Light Theme TradingFinder Switching Colors Library reads red, green, blue, and transparency, classifies brightness into coarse channel buckets, and labels the color as hard dark, hard light, or dark. Matching bucket combinations set per-channel adjustment coefficients used to shift the color. It draws nothing by itself and has no inputs, signals, or trade rules.
- Exported SwitchingColorMode function
- RGB and transparency extraction
- Brightness bucket classification
- Hard dark and hard light labels
- Per-channel color adjustment coefficients

No repainting, lookahead or stacked entries were found in its code or README. That says nothing about how well it works: test it first.
Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints. Check it in the Strategy Tester and on a demo account before you rely on it.
