Exponential Moving Average (EMA)
A moving average that weights recent prices more heavily.
The EMA applies a multiplier so recent prices count more than old ones. It reacts faster than the SMA of the same length, which makes it popular for short-term trading.
The 20 EMA is often used as a pullback guide in trends, and the 50 and 200 EMA as bigger-picture filters. In strong trends, price may hug the 20 EMA.
Faster reaction also means more false signals in sideways markets. Pair it with a trend filter such as the 200 EMA.
Key takeaways
- EMA weights recent prices more
- Reacts faster than SMA
