WHAT IT DOES

What pine_compile does on TradingView MCP Jackson

AI agents invoke pine_compile to trigger actions in TradingView MCP Jackson. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why pine_compile needs a policy

The tool executes user-provided or existing Pine Script code in a live trading context. Pine Script is a domain-specific programming language for TradingView indicators and strategies. Executing arbitrary Pine Script can modify chart state, trigger alerts, execute trading logic, or produce unintended financial market interactions.

From the tool's definition "Compile / add the current Pine Script to the chart" - this tool executes Pine Script code by compiling and adding it to a live trading chart, which triggers code execution in the TradingView environment.
