WHAT IT DOES

What copy_rates_range does on MCP Trader Server

AI agents call copy_rates_range to retrieve information from MCP Trader Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why copy_rates_range is rated Low

The name 'copy_rates_range' strongly resembles MetaTrader 5's built-in CopyRatesRange function, which retrieves historical OHLCV bar data between two dates — a read-only market data operation. No description is provided, so confidence is reduced. Given the server context (trading/market analysis), this is almost certainly a data retrieval tool with no side effects.

From the tool's definition Tool name 'copy_rates_range' suggests retrieving historical rate/price data for a date range, consistent with MetaTrader 5's CopyRates function family
