Definition of Average True Range (ATR)
The Average True Range (ATR) is a technical analysis indicator designed to measure market volatility. It quantifies the range of price movements for a specific asset over a set period, typically using the average of true ranges over the last 14 days. ATR reflects the average price variability, helping traders gauge market noise from genuine trends.
Average True Range (ATR) vs. Historical Volatility (HV)
| Feature | Average True Range (ATR) | Historical Volatility (HV) |
|---|---|---|
| Purpose | Measures current market volatility | Measures past price variability |
| Calculation Method | Based on true ranges over a specific period | Derived from price changes over time |
| Application | Uses a moving average to smooth values | Expressed as a percentage of the asset price |
| Time Frame | Typically 14 days, but can be adjusted for signals | Can be calculated for various time frames |
| Result Interpretation | Indicates volatility and potential price movement | Indicates risk based on past price changes |
Example Calculation of ATR
Step 1: Calculate True Range (TR)
- Current High – Current Low
- Absolute Value of (Current High – Previous Close)
- Absolute Value of (Current Low – Previous Close)
Step 2: Determine the ATR
- ATR = (True Range1 + True Range2 + … + True RangeN) / N
Example Calculation:
- Suppose we have the following data for an asset over 5 days:
| Day | High | Low | Close (previous) | TR |
|---|---|---|---|---|
| 1 | 30 | 25 | - | - |
| 2 | 32 | 27 | 30 | 5 |
| 3 | 31 | 26 | 32 | 5 |
| 4 | 34 | 29 | 31 | 5 |
| 5 | 35 | 30 | 34 | 5 |
- Average True Range for the last 5 days = (0 + 5 + 5 + 5 + 5) / 5 = 4

Humorous Insights and Fun Facts
- J. Welles Wilder Jr. not only created the ATR, but he also likely had enough volatility in his life to write a book about it! 🎢
- Fun fact: The ATR indicator is so beloved by traders that if it were a person, it would definitely be the life of the party, always keeping everyone on their toes!

Frequently Asked Questions (FAQs)
-
What is the significance of the 14-day period in ATR?
- The 14-day period is a common standard, balancing the need for responsiveness and smoothness in the data. Shorter periods create more signals but may lead to “noise”; longer ones smooth out too much. It’s a classic case of “too much of a good thing can be bad!”
-
Can ATR predict future price movements?
- While ATR gives insights into volatility, it doesn’t predict price direction. Think of it as a very astute spectator cheering for the market to decide where it wants to go.
-
Is a higher ATR always better?
- Not necessarily! A higher ATR indicates more volatility, which might suggest riskier assets. Always consider your risk tolerance—it’s a tightrope walk between excitement and potential loss!
