List open positions. Pass symbol to filter to one instrument.
AI agents call get_positions to retrieve information from MetaTrader 5 MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves information about open positions in the trading account. It has no side effects, does not execute orders, close positions, or move money. The read-only nature and informational purpose place it firmly in the Read category with low severity, as misuse would only expose trading position data, not cause financial harm or irreversible changes.
From the tool's definition 'List open positions' — a query operation that retrieves data about existing positions without modifying, deleting, or executing trades. The optional symbol filter is a standard query parameter.
