WHAT IT DOES

What chart_manage_indicator does on Tradingview

AI agents use chart_manage_indicator to create or update resources in Tradingview — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tradingview environment.

WHY IT NEEDS A POLICY

Why chart_manage_indicator needs a policy

The tool modifies the chart's state by adding or removing indicators/studies. Adding is a write operation; removing could be considered destructive, but indicators can be re-added, making it reversible. The most accurate category is Write. Misuse could disrupt analysis workflows but has limited blast radius beyond the local TradingView instance.
