Overview
Most of the scripting API is the same whether you write an indicator or a definition: reading price, declaring settings, drawing on the chart, reading other indicators, other timeframes, sessions, limits and lint. This section covers those shared pieces.
An indicator and a definition run on the same per-bar runtime, so every ctx field on these pages exists on both. A study runs once per event instead, and has its own versions of a few of them. The Indicator, Definition and Study sections cover only what each type adds.
