Send an order to the trade server.
AI agents use order_send to commit financial operations through MetaTrader 5 MCP Server — usually the final step of a payment, billing, or trading workflow. A call moves real money.
This tool directly submits trading orders to a financial market. Misuse by an AI agent could result in unintended trades, significant monetary losses, or unauthorized financial commitments in live forex/financial markets. This is unambiguously a Financial category action with critical severity due to the irreversible real-money impact of executed trades.
From the tool's definition 'Send an order to the trade server' on a MetaTrader 5 server described as 'placing trades, and managing trading positions' in 'forex and financial market operations'
