| Type | Initialism |
The initialism DMA stands for Daily Moving Average in some financial-market commentary. It describes a moving-average context based on daily observations.
Daily describes the time interval, while the window length and averaging method are separate choices. This guide demonstrates a simple arithmetic average of fictional daily closing values. A three-day simple average uses three observations; a five-day simple average uses five. A daily average and a displaced moving average can both be called DMA, so read the chart’s full indicator label before interpreting the letters.
Meaning in context
- Daily
- The observation interval in this use. It does not specify the number of days in the window.
- Moving Average
- An average recalculated across a changing window. The simple arithmetic version here is one declared method.
Practical examples
Name the method
- Before
DMA tells us this must be a five-day simple average.
- After
The note needs its interval, window and method: for example, a five-day simple average of fictional daily closes.
Daily does not supply a period count or select every possible averaging method.
Check a small window
- Before
The latest three fictional values are 12, 14 and 16, so their simple average is 42.
- After
Their sum is 42; dividing by three gives a simple average of 14.
The total and the average are different quantities.

Use DMA with clarity
What information is missing when a chart note says only DMA?
See all guidance
Read the interval
Check whether the underlying observations are daily.
This example uses fictional daily closing values.
Read the window
Count the observations included.
A three-day window contains three daily observations.
Read the calculation
Keep the method explicit.
A simple average divides the selected sum by the number selected.
Change the number of latest observations included and compare the selected sum with its average.
