Introduction to Bollinger Bands
Introduction to Bollinger Bands
Bollinger Bands are a well-known tool for technical analysis that traders use to evaluate the volatility and potential price changes of a financial instrument. John Bollinger developed this indicator in the 1980s. It helps traders spot when the market is overbought or oversold giving them useful insights to make smart trading choices.
What are Bollinger Bands?
Bollinger Bands have three lines: the middle band, the upper band, and the lower band. The middle band is usually a simple moving average (SMA) set at 20 periods. The upper and lower bands are worked out by adding and taking away a standard deviation from the middle band. This creates a range that changes with market ups and downs.
How to Work Out Bollinger Bands
To work out Bollinger Bands, follow these steps:
- Middle Band (SMA): Work out the 20-period simple moving average of the asset’s closing prices.
- Upper Band: Add two standard deviations to the middle band.
- Lower Band: Take away two standard deviations from the middle band.
These calculations give a picture of how prices move and how unstable they are.
Understanding Bollinger Bands
You can use Bollinger Bands in different ways to help with trading plans:
- Too High or Too Low Prices: When the price gets close to the top band, the asset might be too expensive. On the flip side when the price nears the bottom band, it might be too cheap.
- Trend Changes: If the price breaks above the top band or below the bottom band, it could mean the trend might change.
- Signs of Instability: When the bands get closer, it suggests low instability and a possible big move. When they spread out, it shows high instability.
Trading Plans Using Bollinger Bands
Here are a few common trading tactics that use Bollinger Bands:
1. Bollinger Band Squeeze
The Bollinger Band Squeeze tactic spots times of low volatility. When the bands get closer, it signals a possible breakout. Traders look for the price to move above or below the bands to start a trade in the breakout’s direction.
2. Bollinger Band Bounce
The Bollinger Band Bounce tactic involves trading when the price hits the top or bottom band and then goes back toward the middle band. This tactic works well in markets that range where prices move between support and resistance levels.
3. Bollinger Bands and RSI
Using Bollinger Bands with the Relative Strength Index (RSI) has an impact on trading signals. The price touching the upper band and an overbought RSI might signal a good time to sell. On the other hand, the price touching the lower band and an oversold RSI could point to a good time to buy.
Advantages of Bollinger Bands
- Dynamic Range: Bollinger Bands adapt to market conditions giving a more exact picture of volatility.
- Versatility: Traders can use them on different financial products, like stocks, forex, and cryptocurrencies.
- Easy to Use: People find Bollinger Bands simple to grasp and add to their trading plans.
Limitations of Bollinger Bands
- False Signals: Bollinger Bands can give off incorrect signals when markets have low volatility or are trending.
- Lagging Indicator: Since Bollinger Bands lag behind price action, they might not always provide the best timing for entering or exiting trades.
To wrap up
Bollinger Bands are a useful tool for traders who want to understand market volatility and spot potential trading chances. By adding Bollinger Bands to your technical analysis toolkit, you can boost your trading strategies and make better-informed choices. Keep in mind that it’s best to use Bollinger Bands alongside other indicators and analysis methods to improve accuracy and lower the risk of false signals.

On the other hand, if the MACD falls below zero, a cross under the signal line might suggest a possible short trade.
3. How to Pick a Useful Indicator?
Pick an indicator with a pH range that matches the pH of the specific reaction. Take the titration of a strong acid with a strong base as an example. The pH changes from 3 to 11, so phenolphthalein (with a range from pH 8-10) works well as an indicator. Also, think about the color change aspect.
