WHAT IT DOES

What pane_set_symbol does on TradingView MCP Bridge

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

RISK

Why pane_set_symbol is rated Medium

This tool writes/modifies the state of a TradingView chart pane by changing its symbol. It is reversible (you can set it back), so it falls under Write rather than Destructive. Misuse could cause an AI agent to change what symbol a user is viewing, potentially causing confusion during analysis or trading decisions, warranting medium severity.

From the tool's definition 'Set the symbol on a specific pane by index' — modifies the chart configuration by changing the symbol displayed in a pane
