NEBULA RANGE SENTINEL
Bollinger Bands + RSI Signal Indicator for XAUUSD
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Nebula Range Sentinel is a professional Gold trading indicator designed to identify potential reversal opportunities around dynamic market extremes.
The indicator combines Bollinger Bands price rejection and re-entry logic with RSI momentum confirmation, ATR-based Entry, Stop Loss, and Take Profit zones, candle validation, session filtering, signal cooldown, and real-time alerts.
Its purpose is to reduce unnecessary market noise and provide selective BUY and SELL setups supported by multiple confirmation layers.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CORE CONCEPT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Nebula Range Sentinel focuses on situations where price reaches or moves beyond a Bollinger Band and then returns inside the dynamic range.
The RSI filter confirms whether momentum is sufficiently oversold for a potential BUY setup or overbought for a potential SELL setup.
A signal appears only when the required conditions agree.
The indicator is designed for traders who prefer:
✓ Bollinger Band rejection and re-entry setups
✓ RSI overbought and oversold confirmation
✓ Structured Entry, Stop Loss, and Take Profit zones
✓ Confirmed-candle signal validation
✓ Controlled signal frequency
✓ Real-time notifications
✓ A clean and disciplined Gold trading workflow

HOW THE SIGNAL LOGIC WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. GOLD-FOCUSED PRICE ENGINE
The indicator analyzes confirmed Gold candles using an internal mathematical price model.
The calculated ATR target must align with one of the projected price levels before the Bollinger Bands and RSI filters are applied.
2. BOLLINGER BANDS CONFIRMATION
The Bollinger Bands filter identifies potential market extremes.
A potential BUY setup requires:
• Price touches or moves below the Lower Bollinger Band
• The candle closes back above the Lower Band when re-entry confirmation is enabled
A potential SELL setup requires:
• Price touches or moves above the Upper Bollinger Band
• The candle closes back below the Upper Band when re-entry confirmation is enabled
This logic helps identify possible rejection and mean-reversion opportunities.
3. RSI MOMENTUM CONFIRMATION
RSI confirms whether momentum supports the potential reversal.
Default BUY confirmation:
• RSI equal to or below 40
Default SELL confirmation:
• RSI equal to or above 60
Optional RSI slope confirmation can require RSI to begin moving away from the extreme zone.
4. CANDLE CONFIRMATION
When enabled:
• BUY setups require a bullish confirmed candle
• SELL setups require a bearish confirmed candle
This provides an additional validation layer before a signal is displayed.
5. ATR TRADE STRUCTURE
When all required conditions align, the indicator calculates and displays:
• Entry
• Stop Loss
• Take Profit
These levels are based on ATR volatility and automatically adapt to changing market conditions.

WHY USE NEBULA RANGE SENTINEL?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Bollinger Bands alone can generate many premature signals when price continues moving outside the bands.
Nebula Range Sentinel adds multiple filters to create a more selective process:
• Bollinger Bands identify dynamic price extremes
• Re-entry logic confirms rejection back inside the range
• RSI confirms overbought or oversold momentum
• Candle direction validates the setup
• Session filtering controls signal timing
• ATR creates structured risk levels
• One-signal-per-day mode helps reduce overtrading
The result is a structured decision-support tool focused on range extremes, confirmation, and risk control.

CORE SETTINGS
• Gold Step Mode
Controls the internal Gold step calculation.
Automatic mode selects the step according to the active chart timeframe.
• ATR Period
Defines the ATR period used for volatility calculations and trade-zone placement.
• Gold Threshold
Controls the maximum permitted distance between the calculated ATR target and the projected price levels.
A lower value creates stricter target-alignment requirements.
• Historical Bars To Scan
Defines how many historical candles are processed when the indicator is attached to a chart.

Defines the moving-average period used in the Bollinger Bands calculation.
Default value: 20.
• Bollinger Bands Deviation
Defines the standard-deviation multiplier used to calculate the Upper and Lower Bands.
Default value: 2.0.
• Require Band Re-entry
When enabled, price must touch or move beyond a band and then close back inside the range.
This provides stricter rejection confirmation.
• Use Middle-Band Slope
When enabled, the Bollinger middle-band direction must also support the setup.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
RSI FILTER SETTINGS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
