1. Why EMA was developed
Markets change quickly. Traders wanted an average that reacted faster to new information than the SMA.
2. EMA vs SMA
Both average historical prices. The difference is weighting: EMA gives more importance to recent prices, while SMA treats all prices equally.
3. Advantages
Responds faster to trend changes
Useful for shorter-term trend analysis
Commonly used by swing traders
4. Limitations
Can produce more whipsaws in sideways markets
Still lags price because it uses historical data
EMA or SMA?
Neither is universally better. The choice depends on the trading process, timeframe and objective.
DStreet Principle
Choose one methodology and stay consistent. Constantly switching indicators usually creates confusion, not better decisions.
