WHAT IT DOES

What copy_rates_from_pos does on MCP Trader Server

AI agents call copy_rates_from_pos 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_from_pos is rated Low

The name follows MetaTrader 5 naming conventions where 'copy_rates_from_pos' reads historical bar data starting from a given bar index. This is a data retrieval operation with no side effects. Severity is medium due to the financial trading context, though the tool itself only reads market data. Confidence is reduced because the description is empty.

From the tool's definition Tool name 'copy_rates_from_pos' suggests fetching historical rate/price data from a position index, consistent with MetaTrader 5's CopyRates function family which retrieves OHLCV bars from a specified position.
