Bollinger + RSI, Double Strategy (by ChartArt) v1.1

The Bollinger + RSI, Double Strategy (by ChartArt) v1.1 indicator identifies high-probability mean reversion entry points by signaling trades only when the Relative Strength Index (RSI) and Bollinger Bands concurrently confirm overbought or oversold conditions.

Usage

The Usage of this strategy centers on the confluence of momentum and volatility. Users can identify potential market reversals when the price interacts with the outer envelopes of the Bollinger Bands while the RSI confirms a shift in momentum.

• Long Positions: A long entry is triggered when the price crosses above the lower Bollinger Band while the RSI simultaneously crosses above its designated threshold.
• Short Positions: A short entry is triggered when the price crosses below the upper Bollinger Band while the RSI simultaneously crosses below its designated threshold.

The strategy includes visual toggles to highlight these occurrences directly on the chart. By using a longer default period for the Bollinger Bands, the script filters out minor price fluctuations, focusing on significant deviations from the long-term mean.

Details

The Bollinger + RSI, Double Strategy is built on the concept of dual-factor validation. By requiring both a volatility extreme (Bollinger Bands) and a momentum shift (RSI) to occur at the same time, the script aims to reduce false signals common in single-indicator strategies.

In version 1.1, the implementation was refined by transitioning the default Bollinger Band basis to a 200-period Simple Moving Average (SMA). This change provides a more stable baseline for identifying oversold and overbought levels relative to long-term price action. The strategy executes trades based on the close of the candle to avoid repainting issues associated with real-time price fluctuations.

The logic follows these specific conditions:

1. RSI Calculation: Defaults to a short 6-period lookback for high sensitivity.
2. Bollinger Calculation: Defaults to a 200-period SMA with a standard deviation multiplier of 2.0.
3. Confluence Trigger: Entries are generated only when a crossover (for longs) or crossunder (for shorts) occurs on both indicators within the same bar.

Settings

• RSI Period Length: Determines the number of bars used to calculate the Relative Strength Index. Lower values increase sensitivity.
• Bollinger Period Length: Sets the lookback period for the Simple Moving Average that forms the basis of the Bollinger Bands.
• Enable Bar Color: When active, changes the color of the price bars when a trade condition is met.
• Enable Background Color: When active, applies a colored background highlight to the chart when signals are triggered.

FAQ

What is the benefit of combining RSI with Bollinger Bands? Combining these indicators ensures that a trade is only taken when price is at a statistical extreme (Bollinger Bands) and showing a specific momentum recovery (RSI), which helps filter out "falling knife" scenarios.

Can this strategy be used on lower timeframes? Yes, though the 200-period Bollinger Band setting is designed to capture broader trends. Users on lower timeframes may wish to adjust the Bollinger Period Length to suit local volatility.
