Calculate the Weighted Moving Average (WMA) for a stock using the FMP WMA API. This tool helps users analyze trends and identify potential buy or sell signals based on historical price data.
AI agents call getWMA to retrieve information from Financial Modeling Prep MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
getWMA retrieves historical stock price data and performs a computational analysis (weighted moving average calculation) to derive a technical indicator. No data is created, modified, deleted, or financial transactions are executed. This is purely a read operation that queries financial data and returns an analytical result.
From the tool's definition Tool description states it 'Calculate[s] the Weighted Moving Average (WMA) for a stock' and 'help[s] users analyze trends' based on 'historical price data'.
