SMA vs DMA: Simple vs Displaced Moving Average
Moving averages are among the most widely used technical indicators. While the Simple Moving Average is standard, the Displaced Moving Average shifts the line forward or backward in time to anticipate or confirm trends differently.
What Is SMA?
The Simple Moving Average (SMA) calculates the average price over a set number of periods. It is straightforward, widely supported, and gives equal weight to every price in the lookback period.
What Is DMA?
The Displaced Moving Average (DMA) takes a standard moving average and shifts it forward or backward by a set number of periods. This displacement can help identify support and resistance levels ahead of time.
Key Differences
| Feature | SMA | DMA |
|---|---|---|
| Calculation | Average of N prices | SMA shifted by X periods |
| Complexity | Simple | Slightly more complex |
| Leading/lagging | Lagging | Can be leading (forward shift) |
| Use case | Trend following | Anticipating support/resistance |
| Popularity | Very common | Niche usage |
The Bottom Line
Both SMAs and DMAs have their place. SMA is the standard starting point for most traders, while DMA is a useful variant for those who want to experiment with displaced support and resistance levels.
