What is EMA (exponential moving average)?
MA Cross
EMA (Exponential Moving Average) is a moving average that gives more weight to recent prices. Unlike the simple moving average (SMA), which treats all days' prices equally, the EMA reflects the idea that yesterday's price is more important than the price 30 days ago.
EMA vs SMA — Which should you use in practice?
| Compare | SMA (simple) | EMA (index) |
|---|---|---|
| reaction speed | slow | Fast |
| noise | Less | many |
| Trend Following | stable | sensitive |
| Short-term use | unsuitable | Fit |

Conclusion: Short-term scalping/short term → EMA / Confirm long-term trend → SMA 200
Meaning of each major EMA period
