Get pricing and contract details for a symbol (digits, point, tick_size, tick_value, contract_size, volume bounds, bid, ask).
AI agents call symbol_info 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.
symbol_info queries market data and instrument specifications. It is read-only information retrieval used to support trading decisions but does not itself execute trades, modify positions, delete data, or commit financial obligations. While the server context is financial trading, this specific tool only fetches reference data needed for risk calculations and order placement by other tools.
From the tool's definition Tool retrieves pricing and contract details for a symbol (digits, point, tick_size, tick_value, contract_size, volume bounds, bid, ask) — pure data query with no side effects, state modification, or external action triggers.
