BB2/2.5ハイライト

Indicator Name: **BB2/2.5 Highlight**

1. **Introduction**
BB2/2.5 Highlight displays two Bollinger Bands—inner at ±2 σ and outer at ±2.5 σ—while hiding the middle band. The space between the two bands is shaded gray to help you spot strong momentum or unusually large price movements at a glance.

2. **Key Features**

* **Double-Band Display**: Plots inner band (±2 σ) and outer band (±2.5 σ) simultaneously.
* **Zone Highlight**: Shades the area between the two bands to emphasize high-momentum zones.
* **Full Customization**: Adjust period, deviations, line colors, line transparency, and shading color directly via inputs.

3. **Parameters**

* **Length** (Period)
– The number of bars used to calculate the moving average. Default: 20
* **Std Dev 1** (Inner Band Deviation)
– Multiplier for standard deviation of the inner band. Default: 2.0
* **Std Dev 2** (Outer Band Deviation)
– Multiplier for standard deviation of the outer band. Default: 2.5
* **Color Band 1** (Inner Band Color)
– Color of the ±Std Dev 1 lines. Default: Blue
* **Color Band 2** (Outer Band Color)
– Color of the ±Std Dev 2 lines. Default: Orange
* **Line Transparency**
– Transparency of both band lines, 0 (opaque) to 100 (invisible). Default: 30
* **Shading Color**
– Color and transparency of the shaded area between bands. Default: Gray at 85% opacity

4. **How to Use & Interpretation**

* **Break above inner band (±2 σ)**
Indicates accelerating trend strength or strong momentum.
* **Break above outer band (±2.5 σ)**
Signals an extreme move—potential overbought/oversold condition and possible reversal points.
* **Shaded Zone (±2 σ to ±2.5 σ)**
Visually marks the range where price is exhibiting particularly strong momentum.

5. **Customization Examples**

* **Change deviations to ±1.5 / ±3.0**
Set Std Dev 1 = 1.5, Std Dev 2 = 3.0
* **Use green/red band colors**
Set Color Band 1 = #00FF00, Color Band 2 = #FF0000
* **Increase transparency to 50%**
Set Line Transparency = 50
* **Light-blue shading**
Set Shading Color = #ADD8E6 at 85% opacity

6. **Notes & Warnings**

* Bollinger Bands are based on historical volatility; they do not predict future price action.
* Always combine with other technical tools or fundamental analysis for confirmation.
* Behavior may vary across timeframes and instruments—backtest and paper-trade before going live.

7. **Conclusion**
BB2/2.5 Highlight makes “strong momentum” zones immediately visible by combining a ±2 σ/±2.5 σ double‐band with a shaded area. All inputs are adjustable, so tailor the settings to fit your trading style and use the indicator to time entries and exits more effectively.
