Technical indicators

SMA, EMA, WMA, DEMA, TEMA, RSI, ADX, Williams %R, and standard deviation series.

Call these with cvApi.call('/fmp/stable/<endpoint>', params) in an app, GET /api/data/fmp/stable/<endpoint> over REST, or the fmp_request MCP tool from a coding agent. Available on every plan; requests count against your hourly limit.

Average Directional Index

GET /api/data/fmp/stable/technical-indicators/adx

Indicator measuring trend strength on a 0–100 scale, derived from smoothed directional movement and used to separate trending markets from ranging ones.
