Exponential Moving Average (EMA)
AI agents call technicalIndicators_ema to retrieve information from MCP Avantage without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
EMA is a standard technical indicator used in financial analysis to smooth price trends. It performs calculations on existing market data to derive insights, with no side effects, no data modification, and no financial commitments. This is purely a Read operation—querying and analyzing historical data to produce derivative metrics.
