Input Functions
User-configurable script parameters in PyneCore
Input Functions
Input functions allow Pine Script users to configure script parameters through a settings dialog. In PyneCore, the PyneComp compiler transforms these into parameter declarations with default values.
How Inputs Work in PyneCore
In TradingView, input.*() functions create interactive UI controls. Since PyneCore runs
offline without a UI, input values are resolved at compile time to their default values.
Future versions may support external configuration files for input overrides.
Available Input Functions
