Bollinger Bands are a popular technical analysis tool used in trading. Here's a basic overview of a Bollinger Band trading strategy:

*What are Bollinger Bands?*

Bollinger Bands consist of three lines:

1. A moving average (usually 20-period)

2. An upper band (usually 2 standard deviations above the moving average)

3. A lower band (usually 2 standard deviations below the moving average)

*Basic Strategy:*

1. *Buy Signal:* When the price touches or breaks below the lower band, it may be oversold, and a buy signal is generated.

2. *Sell Signal:* When the price touches or breaks above the upper band, it may be overbought, and a sell signal is generated.

*Additional Tips:*

1. Use Bollinger Bands in conjunction with other indicators or chart patterns for confirmation.

2. Adjust band settings (e.g., period, standard deviation) according to market conditions.

3. Be cautious of false signals and use risk management techniques.

*Advanced Strategies:*

1. *Squeeze Play:* When bands contract, it can signal a potential breakout.

2. *Band Walk:* When price walks along the band, it can indicate strong momentum.

Keep in mind that no strategy guarantees success, and Bollinger Bands should be used in conjunction with other forms of analysis and risk management.
