EMA (Exponential Moving Average) 조회
AI agents call technical_ema to retrieve information from PM-MCP (Portfolio Management MCP Server) without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves technical analysis data (Exponential Moving Average calculations) without side effects. It performs a read-only data retrieval operation typical of portfolio analysis platforms. The low severity reflects that misuse only retrieves historical or computed market metrics, with no impact on actual holdings, accounts, or external systems.
