Live Bollinger Buy/Sell Signal + Custom EMA by RAJU

📌 DESCRIPTION
Live Bollinger Buy/Sell Signal is a price-action-based entry system built on Bollinger Bands. This indicator automatically detects high-probability reversal points when price interacts with the outer Bollinger Bands and provides instant Buy & Sell signals directly on the chart. It is designed for traders who want clean and fast signals without complex settings.
________________________________________
🧠 LOGIC OF INDICATOR
The indicator uses a standard Bollinger Band setup (SMA + Standard deviation).
A Buy or Sell signal is triggered when a candle forms outside or near the Bollinger Band extremes and then reverses direction. This behaviour often indicates a potential trend reversal or strong bounce from volatility exhaustion.

🟩 LONG CONDITION (Buy Signal)
A Buy signal is plotted when:
• The candle closes bullish (close > open)
• The candle opens below the lower Bollinger Band
• The candle closes back above the lower Bollinger Band
• The next candle must trade above signal candle
• If a candle before or after signal candle closes without touching 5 EMA then probability of reversal is high (optional)
This indicates a strong price rejection from oversold levels.

🟥 SHORT CONDITION (Sell Signal)
A Sell signal is plotted when:
• The candle closes bearish (close < open)
• The candle opens above the upper Bollinger Band
• The candle closes back below the upper Bollinger Band
• The next candle must trade below signal candle
• If a candle before or after signal candle closes without touching 5 EMA then probability of reversal is high (optional)
This indicates a strong rejection from overbought levels.
