Alpha Vantage EMA (Exponential Moving Average)

Use this endpoint when you need EMA values specifically — it applies exponential weighting that gives more importance to recent prices compared to SMA. Prefer EMA over SMA for responsive trend-following strategies, crossover signals (e.g. 12/26 EMA), or momentum indicators like MACD components. Choose this over raw price time series when you need the smoothed trend line directly without computing it yourself.
