The Exponential Moving Average (EMA) is a trend-following indicator that gives more weight to recent prices, making it more responsive than the Simple Moving Average (SMA). It helps smooth out price fluctuations and highlights the direction of the trend. The EMA is widely used in both short-term and long-term trading to identify trend reversals, entry/exit points, and dynamic support or resistance.
💡 Significance
- Responds faster to recent price changes than SMA.
- Identifies trend direction more clearly in real-time markets.
- Provides support/resistance zones in trending markets.
- Useful for early entries/exits in momentum trading.
- Widely used in combination with other indicators like MACD or RSI.
