Bollinger Band Breakout

The Bollinger Band Breakout indicator is a trend-following strategy designed to capture long-side momentum when price action breaches the upper volatility envelope.

Usage

The strategy enters a long position when the closing price crosses over the Upper Bollinger Band. This signal suggests a potential increase in bullish momentum and the start of an uptrend.

Users can choose between two distinct exit mechanisms based on market conditions:

• Lower Band Exit (Option 1): The strategy closes the position when the price crosses under the Lower Bollinger Band. This option is typically preferred for highly volatile instruments, as it allows more room for the price to fluctuate within the bands before exiting.
• Basis (SMA) Exit (Option 2): The strategy closes the position when the price crosses under the middle basis line (Moving Average). This is often used in less volatile markets to lock in profits earlier when the trend shows signs of weakening.

Details

The script utilizes the standard Bollinger Band calculation, consisting of a Simple Moving Average (SMA) and two standard deviation bands. By focusing on breakouts above the upper band, the script identifies periods where price strength is significantly higher than its recent average.

The strategy is built as a "long-only" system, making it suitable for trending equity markets or assets with a long-term bullish bias. Note that backtesting results do not account for slippage or commissions.

Settings

• Period: Sets the lookback length for the Simple Moving Average and the Standard Deviation calculation (default is 20).
• Standard Deviation: Determines the multiplier for the bands. A value of 1.5 is common for 20-period lengths, while 2.0 is often used for shorter periods.
• Exit Option: Toggles between the two exit methodologies. Select "1" for the Lower Band exit or "2" for the Moving Average (Basis) exit.
