What are Bollinger Bands, and how to read them
Bollinger Bands are an easy and intuitive technical analysis tool. They help traders to identify when the market is overbought or oversold and whether the volatility is high or low.
Bollinger Bands are an intuitive and powerful technical analysis tool that helps traders identify market conditions, including overbought or oversold signals and volatility levels.
A Bollinger Band consists of a simple moving average (middle band), an upper band, and a lower band. These bands represent standard deviations (positive and negative) from a simple moving average. The lower band is positioned below the moving average, while the upper band is set above it.

Understanding Bollinger Bands
The width of the bands indicates market volatility. When the bands are narrow, volatility is low; when they widen, volatility is high.
If the asset price moves close to the upper band, the market may be overbought.
If the asset price moves near the lower band, the market may be oversold.
The Bounce
97% of all price changes occur within the Bollinger bands. And the price tends to return to the middle band. This is the idea behind the Bounce.
So, if the price reaches the top of the band, it is more likely to start moving downward and settle somewhere close to the middle band.
The reason why it occurs is that the lower and upper bands act like support and resistance levels.
This principle works when the price moves in the range determined by the Bollinger bands when there is NO trend in the market. When the market is trending, other patterns are used.

The Squeeze
When the bands come very close to each other, it is called a squeeze. It means that the volatility is very low, and soon, you can expect a breakout. If the price breaks out above the upper band, it normally continues going up (the market is trending).
And on the contrary, if the price breaks out below the lower band, the market is in a downtrend, and the price will most likely continue to fall.

Avoiding False Signals
False signals can occur in choppy or sideways markets. To minimize false signals when using Bollinger Bands:
Confirm with other indicators such as RSI, MACD, or volume.
Analyze trend direction to ensure price moves align with market trends.
Use stop-loss strategies to manage risk effectively.
Avoid over-relying on Bollinger Bands in isolation; combine them with other technical analysis tools.

Calculation of Bollinger Bands
Bollinger Bands are calculated using a simple moving average (SMA) and standard deviation.
Formula:
Middle Band = 20-day SMA
Upper Band = 20-day SMA + (2 × Standard Deviation)
Lower Band = 20-day SMA - (2 × Standard Deviation)
Key variables used:
Standard deviation: Measures price volatility.
Bandwidth: The difference between the upper and lower bands.
Moving averages: Used to calculate trend direction.

Comparison with Other Indicators
Bollinger Bands can be compared with other technical indicators to improve their effectiveness:
Relative Strength Index (RSI): Confirms overbought or oversold conditions.
MACD: Identifies trend strength and reversals.
Keltner Channels: Similar to Bollinger Bands but based on ATR instead of standard deviation.
Parabolic SAR: Helps detect trend reversals.

Limitations of Bollinger Bands
While Bollinger Bands are a valuable tool, they have limitations:
Lagging indicator: Relies on past price data, which may not always predict future trends accurately.
Not a standalone predictor: Should be combined with other indicators.
Market conditions: Less effective in highly volatile markets or extreme price swings.
Risk management: Traders should use stop-loss orders to minimize losses.
Understanding these limitations helps traders use Bollinger Bands more effectively within a well-rounded strategy.
