Introduction
In this section, we’ll explore two essential volatility indicators widely used in technical analysis: Bollinger Bands and the Average True Range (ATR). Understanding these tools is crucial for anyone preparing for the FINRA Series 7 exam, as they provide insights into market volatility and potential trading signals. Quizzes at the end will help reinforce your understanding and test your exam readiness.
Bollinger Bands
Understanding Bollinger Bands
Bollinger Bands consist of a moving average and two standard deviations plotted away from the moving average. This setup allows traders to visualize volatility as the bands expand and contract in response to market conditions.

Trading Signals
Price movements in relation to the Bollinger Bands can signal potential market trends. When prices approach the upper band, it suggests an overbought market, while approaching the lower band suggests an oversold market. These indicators can guide traders in making buy or sell decisions.
Average True Range (ATR)
The Average True Range (ATR) measures market volatility by evaluating the range within which an asset price moves. Unlike Bollinger Bands, which use a moving average, ATR focuses on the entirety of price movement over a specific period, providing a clearer picture of potential market fluctuations.
Calculating ATR
The formula for the Average True Range is:
\[
\text{ATR} = \frac{\sum \text{True Range}_i}{n}
\]
Where \( \text{True Range} = \max(\text{High} - \text{Low}, |\text{High} - \text{Close Previous}|, |\text{Low} - \text{Close Previous}|) \).
Conclusion
Understanding Bollinger Bands and ATR is essential for those preparing for the FINRA Series 7 exam. These indicators provide valuable insights into market volatility, assisting in making informed investment recommendations. Practicing with quizzes will cement this knowledge and aid in exam success.

### Which indicator uses standard deviations to measure volatility?
- [x] Bollinger Bands
- [ ] Average True Range
- [x] MACD
- [ ] RSI
> **Explanation:** Bollinger Bands use standard deviations around a moving average to measure volatility.

- [x] High market volatility
- [ ] Low market volatility
- [ ] Overbought conditions
- [ ] Oversold conditions
> **Explanation:** A wide distance between the bands indicates higher market volatility.
### What is the formula component of ATR?
- [x] True Range
- [ ] MACD line
- [x] RSI value
- [ ] Moving average
> **Explanation:** The ATR is calculated using the true range of an asset's price movements.
### How many standard deviations are used in typical Bollinger Bands?
- [x] Two
- [ ] One
- [ ] Three
- [ ] Five
> **Explanation:** Bollinger Bands usually employ two standard deviations from the moving average.
### Bollinger Bands help identify which conditions?
- [x] Overbought or oversold
- [ ] Earnings expectations
- [ ] Dividend declarations
- [ ] Tax liabilities
> **Explanation:** By observing where the price falls relative to the bands, one can infer overbought or oversold conditions.
### True or False: ATR provides information about price direction.
- [x] False
- [ ] True
> **Explanation:** ATR measures volatility, not price direction. It does not predict which way the market will move.
