What is EMA (Exponential Moving Average)?
A moving average that weights recent prices more heavily, responding faster to new information than a simple average of the same length.
Formula
EMA = (Close − Prior EMA) × (2 ÷ (N + 1)) + Prior EMA
How to Interpret
Same grammar as the SMA — price above a rising EMA confirms trend, fast/slow EMA crossovers signal momentum shifts — but signals arrive earlier at the cost of more false starts. Faster response means more whipsaws in choppy markets.
Typical Ranges
Common periods: 9 and 21 (short-term), 50 (medium), 150 and 200 (long-term regime). Very short price histories produce unreliable early EMA values.
