A moving average smooths out short-term fluctuations in data by averaging values over a sliding window. Simple moving averages (SMA) and exponential moving averages (EMA) are core tools in financial analysis and signal processing.
- 1SMA(n) = average of last n values
- 2EMA uses a weighting factor k = 2/(n+1)
- 3EMA(t) = value×k + EMA(t−1)×(1−k)
- 4EMA reacts faster to recent changes than SMA
