WHAT IT DOES

What trade_modify does on MetaTrader5 MCP Server

AI agents use trade_modify to commit financial operations through MetaTrader5 MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why trade_modify is rated Critical

On a MetaTrader5 trading server, 'trade_modify' almost certainly modifies open positions or pending orders (e.g., stop-loss, take-profit, price levels). This directly affects financial positions and obligations. The empty description lowers confidence slightly, but the server context (forex trading, real-time quotes) and sibling tools make financial classification highly likely.

From the tool's definition Tool name 'trade_modify' on a MetaTrader5 server with trading functionality; description is empty but context strongly implies modification of open trades/orders.
