How this service works
Get the exponential moving average (EMA) for a ticker symbol over a given time range. Can't find what you're looking for? POST feedback to /feedback, no charge.
Output
Returns a time-ordered series of EMA values for the requested ticker, each entry containing a timestamp and the computed EMA price. Supports filtering by date range, configuring the smoothing window, timespan granularity, price series type (open/high/low/close), and split-adjustment. Results can be paginated up to 5000 entries.
Example use cases
Golden cross trend detection
“Pull the 50-day and 200-day EMA for SPY using daily close prices — I want to check if a golden cross is forming. Give me the last 20 results in ascending order.”
Short-term momentum scalping
“Get me the 10-period EMA for TSLA on an hourly timespan using close prices, last 50 data points descending — I'm looking for short-term momentum signals.”
Backtesting EMA crossover strategy
“I need the 12-day and 26-day EMA values for MSFT over the past year, daily close prices, up to 365 results in ascending order so I can backtest a crossover strategy.”
Technical details
Endpoint
GEThttps://agent.massive.com/v1/indicators/ema/:stockTickerWhen to prefer
Use this endpoint when you need exponential moving averages for technical analysis of US stocks or OTC tickers with configurable windows and timespans. Prefer EMA over SMA when you want more weight placed on recent prices. Choose this over the Simple Moving Average sibling endpoint when responsiveness to recent price changes matters (e.g. momentum or trend-following strategies). Best for agents performing technical charting, trend detection, or quantitative backtesting.
Side effects
- Invalid or unsupported ticker symbol returns an error or empty results
- Window size too large for available data history returns sparse or empty series
- Case-sensitive ticker mismatch causes no results (e.g. 'aapl' instead of 'AAPL')
- Timestamp range with no market data (weekends, holidays) may return empty results
- Exceeding max limit of 5000 returns a validation error
- Unavailable timespan for a given ticker (e.g. minute-level data not available for OTC)
