WHAT IT DOES

What sell_market does on MCP Trader Server

AI agents use sell_market to commit financial operations through MCP Trader Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why sell_market is rated Critical

This tool places a live market sell order through MetaTrader 5, immediately committing a financial transaction at the current market price. Market orders execute instantly and cannot be undone, making this both Financial and potentially Destructive in nature. The Financial category takes precedence as it directly moves assets/money. Misuse by an AI agent could result in significant, immediate financial losses.

From the tool's definition sell_market: 'Place a market sell order' — directly executes a financial trade at current market price
