Average True Range (ATR)
What is Average True Range (ATR)?
Average true range (ATR) is a technical indicator that measures the volatility of an asset's average daily price movements.
How Does Average True Range (ATR) Work?
Average true range starts with the concept of "true range." True range (TR) is calculated by choosing the largest number from the following:
- Current high less current low
- Current high less previous close
- Current low less previous close
Use the absolute value of each metric to ensure positive numbers and pick the largest. Then, average the TR from each of the most recent 14 days to calculate average true range (ATR).
