PineTS Runtime Engine

The runtime environment executes the transpiled code. It simulates the Pine Script execution model where the script runs once for every bar in the dataset.

Key Components

  • PineTS Class: The entry point. Manages the data provider, pagination, and execution loop.
  • Context Class: The “Global State” passed to the script. Holds all variables, series data, and namespace instances.
  • Series Class: The fundamental data structure wrapping arrays.

Execution Model

PineTS follows a “Push-Based” execution model:

  1. Load Data: Fetch OHLCV data from a Provider.
  2. Initialize Context: Create the $ object.
  3. Run Loop:
    • For each historical bar:
      • Update context.idx.
      • Push new OHLCV data into context.data arrays.
      • Execute the user script.
      • Grow all user variables (push current value to history).
    • Collect results/plots.

This ensures that close[1] always refers to the data from the previous iteration.
