trader_resume · Tradingview MCP: Risk & Policy

WHAT IT DOES

What trader_resume does on Tradingview

AI agents invoke trader_resume to trigger actions in Tradingview. 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 trader_resume needs a policy

This tool resumes a paused system/workflow, which constitutes triggering an external operation. Given the trading/financial context (TradingView with automation capabilities including alerts and chart management), resuming automation could trigger trades or alerts, but the tool itself is an execution control action rather than a direct financial transaction.

From the tool's definition 'Reanuda el sistema después de una pausa' (Resumes the system after a pause) — triggers an external operational state change in the TradingView Desktop app via Chrome DevTools Protocol
