What Is SMA?
SMA stands for:
- Simple Moving Average
It is a trend-following indicator that calculates the average price of a stock or asset over a specific number of periods.
The SMA smooths price fluctuations and helps traders identify the overall market direction.
Simple Definition of SMA
A Simple Moving Average is the average closing price of an asset over a specified number of periods.
Why SMA Is Important
SMA helps traders:
- Identify trends
- Reduce market noise
- Spot support and resistance levels
- Confirm breakouts
- Generate trading signals
It is one of the first indicators beginners learn in technical analysis.
SMA Formula
The Simple Moving Average is calculated using:
SMA=nP1​+P2​+P3​+…+Pn​​
Where:
- P = Closing price
- n = Number of periods
Example of SMA Calculation
Suppose the last 5 closing prices are:
- ₹100
- ₹105
- ₹110
- ₹115
- ₹120
Calculation:
SMA=5100+105+110+115+120​=110
The 5-day SMA equals:
- ₹110
How SMA Works
The SMA creates a smooth line on the chart.
As new prices are added:
- Old prices are removed
- The average updates continuously
This helps traders focus on the trend instead of short-term price fluctuations.
