Overview
MathConstantsUniversal exports high-precision numerical values including the speed of light, gravitational constant, Planck constant, magnetic permeability, and electric permittivity based on CODATA standards. The library contains no user-configurable settings and does not plot or generate signals on the chart. It serves strictly as a calculation helper for other scripts requiring universal scientific constants, with no visual output or direct trading functionality.
- Universal physical constant exports
- Speed of light calculation function
- Gravitational and Planck constant exports
- Electromagnetic vacuum permeability and permittivity

Risk Notes
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.
