ICT First FVG - 9:30am & Custom (v4)

ICT First FVG - 9:30am & Custom Time Ranges (v4)
📖 DESCRIPTION
This comprehensive Pine Script indicator identifies and displays Fair Value Gaps (FVGs), Volume Imbalances (VIs), and Liquidity Voids (LVs) based on Inner Circle Trading (ICT) concepts. The indicator offers dual functionality: traditional 9:30am New York session FVG detection and customizable time range analysis for maximum flexibility.
🚀 KEY FEATURES
Dual Detection System

9:30am NY Open FVG: Classic ICT first presentation detection after market open
Custom Time Range FVG: User-configurable time periods for specialized analysis
Independent Operations: Both systems work simultaneously without interference
Separate Controls: Each system has its own settings and previous days configuration

Advanced Gap Detection

Fair Value Gaps (FVG): Three-candle patterns showing price inefficiencies
Volume Imbalances (VI): Single candle volume-related gaps
Liquidity Voids (LV): Areas where price moved too fast, creating liquidity gaps
Consequent Encroachment (CE): Midpoint lines of detected inefficiencies

Precision Sizing System

Multi-Asset Support: Automatic point/pip calculation for Forex, Futures, and Indices
Forex Handling: Specialized pip calculation for major pairs and JPY crosses
Size Filtering: Minimum gap size filter to eliminate noise
Real-Time Display: Shows exact gap sizes in labels (e.g., "15.3 pips" or "12.7 pts")

Professional Visualization

Dual Display Modes: Choose between solid blocks or line representations
Color Coding: Different colors for current vs. previous day imbalances
Smart Labels: Configurable date, time, type, and size information
Extension Options: Extend gaps to session end or current bar

M1 Data Integration

High Accuracy: Uses 1-minute data regardless of chart timeframe
Better Detection: More precise gap identification on higher timeframes
Flexible Usage: Works on any timeframe ≤15 minutes

🎯 PRACTICAL APPLICATIONS
ICT Trading Concepts

First Presentation: Initial FVG after 9:30am NY open
Return to Gap: Price revisiting inefficiency areas
Mitigation Levels: Using FVG boundaries as support/resistance
Liquidity Hunting: Understanding where price seeks efficiency

Multi-Session Analysis

London Close: Set custom range for 1600-1601 London close gaps
Asian Session: Configure overnight inefficiencies
Power Hour: Analyze 1500-1600 ET gaps
Lunch Hour: Study 1200-1300 ET price behavior

Risk Management

Size-Based Filtering: Focus on significant gaps only
Historical Context: Compare current gaps to previous days
Confluence Trading: Combine with other ICT concepts
Session-Specific: Target gaps from specific market sessions

⚠️ IMPORTANT NOTES
Performance Considerations

Maximum Objects: Indicator creates multiple visual elements
Historical Limit: Adjust "Previous Days" to balance history vs. performance
Chart Refresh: Allow time for initial loading on historical data

Data Quality

Broker Dependency: Gap detection accuracy depends on data feed quality
Weekend Gaps: Sunday gaps may appear due to data provider differences
Fast Markets: Extremely volatile periods may create false gaps

Best Practices

Timeframe Consistency: Use same timeframe for analysis and execution
Size Calibration: Adjust minimum sizes based on instrument volatility
Session Awareness: Understand which sessions produce most relevant gaps
Confirmation: Use additional ICT concepts to confirm gap validity
