ICT First Presented FVG with Volume Imbalance [1st P. FVG + VI]

The indicator identifies and highlights the first presented Fair Value Gap (FVG) occurringthe morning (09:30–10:00) and afternoon (13:30–14:00) session's first 30 minutes. It includes an optional feature to extend FVG zones when a volume imbalance (V.I.) is detected, providing additional context for areas of potential price inefficiency. This powerful combination helps traders identify significant market structure gaps that often act as support/resistance zones and potential price targets.

What is an FVG?

A Fair Value Gap, often abbreviated as FVG, is a price range on a chart where there is an inefficiency or imbalance in trading. This typically happens when price moves rapidly in one direction, leaving a gap between the wicks or bodies of three consecutive candles. For example, in a bullish move, if the low of the third candle is higher than the high of the first candle, the space between them is the FVG.

What is a Volume Imbalance?

A volume imbalance is a smaller, more precise inefficiency within price action, often visible as a "crack" or thin area in the price delivery. It represents a spot where the volume traded was not balanced between buyers and sellers, often seen as a thin wick or a gap between candle bodies.

FVG + Volume Imbalance:

When you have a fair value gap that contains a volume imbalance, it becomes a more significant area of interest. ICT teaches that you should not ignore a volume imbalance if it’s part of an FVG. In fact, you should use the volume imbalance in conjunction with the FVG to define your trading range more accurately

📊 Volume Imbalance Integration

• Extended Boundaries: When enabled, FVG boundaries expand to include volume imbalance zones
  
• Accurate Gap Sizing: Total gap calculation includes volume imbalance extensions
  
• Multi-Scenario Support: Handles volume imbalances at start, end, or both sides of FVG formations
  

📈 Multiple Display Modes

• Current Day: Shows only today's FVGs for clean chart analysis
  
• Current Week: Displays all weekly FVGs for broader context
  
• Forward Extension: Extends FVG boxes and CE, Upper/Lower Quadrant lines into the future
  

📊 Visualization

• Bullish FVGs appear in semi-transparent blue or purple zones (depending on session).
  
• Bearish FVGs appear in red or orange zones.
  
• Optional dotted lines mark the CE (midpoint) of each FVG for additional reference.
  
• Quadrant Division: Additional 25%/75% lines for large FVGs (configurable minimum gap size)
  

🎯 Smart Filtering

• First Presentation Only: Only displays the initial FVG in each session, avoiding clutter

How It Works

FVG Boundary Calculation

• Traditional FVG: High[2] to Low[0] (bullish) or Low[2] to High[0] (bearish)
  
• Enhanced FVG: Extended boundaries to include volume imbalance zones when enabled
  
• Total Gap Size: Calculated including any volume imbalance extensions
  

Volume Imbalance Detection

• The indicator identifies volume imbalances by detecting bars where:
  
• Bullish Imbalance: Current bar's body is completely above previous bar's body
  
• Bearish Imbalance: Current bar's body is completely below previous bar's body
