BB vs EMA 9 Gap Signals
### Bollinger Band EMA Gap Signal
This indicator identifies potential **BUY and SELL opportunities** by comparing the distance between the **9-period EMA** and the upper/lower Bollinger Bands.
#### How It Works
The indicator calculates two distances:
* **X** = Upper Bollinger Band − 9 EMA
* **Y** = 9 EMA − Lower Bollinger Band
### 🟢 BUY Signal
A BUY signal is generated when:
1. **Y > X**, meaning the Lower Bollinger Band is farther from the 9 EMA than the Upper Bollinger Band.
2. Price **touches or crosses the Lower Bollinger Band**.
This identifies situations where downside volatility has expanded significantly relative to upside volatility.
### 🔴 SELL Signal
A SELL signal is generated when:
1. **X > Y**, meaning the Upper Bollinger Band is farther from the 9 EMA than the Lower Bollinger Band.
2. Price **touches or crosses the Upper Bollinger Band**.
This identifies situations where upside volatility has expanded significantly relative to downside volatility.
### Key Features
* Uses a **9-period EMA**.
* Uses standard **20-period Bollinger Bands with 2 standard deviations** by default.
* Requires price to touch or cross the relevant Bollinger Band.
* Generates BUY and SELL signals immediately when the conditions are satisfied.
* Includes alert conditions for TradingView alerts.
**Note:** The signals are based on technical conditions and should not be considered guaranteed entry or exit points. Always combine the indicator with proper risk management and market context.
