📘 Summary

FVG RADAR Scanner is a Fair Value Gap detection, directional liquidity intelligence, and radar-based market imbalance framework designed to transform traditional FVG scanning into a structured visual market detection system.

🔷 RADAR = Range Analysis Detection And Reaction
This framework expands beyond traditional Fair Value Gap indicators by combining:
• Range positioning
• Structural analysis
• Imbalance detection
• Contextual liquidity integration
• Strategic trader reaction
Rather than only plotting bullish and bearish imbalance zones, this framework scans historical price action, identifies Fair Value Gaps, tracks whether they remain active or filled, estimates directional buy/sell participation, and converts these structures into a radar-style interface that visually maps liquidity zones, imbalance strength, and bull vs bear dominance around current market price.
This creates a hybrid between:
• Fair Value Gap Scanner
• Liquidity Mapping Engine
• Radar Visualization System
• Directional Volume Allocation Dashboard
• Bull vs Bear Dominance Scanner
The result is a structured market intelligence environment where traders can monitor:
• Range location relative to liquidity
• Where imbalance originated
• Which FVGs remain active
• Which side (bulls or bears) created stronger displacement
• Which gaps are strongest
• Which zones are closest to current price
• How FVGs are detected, filtered, and converted into radar targets
• Whether nearby liquidity is currently being scanned
• Whether directional flow currently favors buyers or sellers

📘 Features

📘 Logic

🔷 Core Concept: Radar for Market Imbalance
Traditional Fair Value Gap indicators often focus only on plotting static imbalance zones.
FVG Radar Scanner expands this concept by combining liquidity location, directional pressure, structural imbalance, target qualification, and trader response into a broader strategic framework:

🔷 RADAR = Range Analysis Detection And Reaction

🔷 R — Range
Where is price positioned relative to surrounding liquidity?
The radar rings spatially organize qualified FVGs around current market price:
• Inner Ring → Closest liquidity
• Middle Ring → Mid-range liquidity
• Outer Ring → Major liquidity zones
снимок

🔷 A — Analysis
What is happening structurally?
The framework analyzes:
• Bull vs Bear count
• Buy vs Sell flow
• MAX strength
• Structural dominance
снимок

🔷 D — Detection
What imbalance currently exists?
Using 3-candle displacement logic:
Bullish FVG: Current low > High 2 candles ago
Bearish FVG: Current high < Low 2 candles ago

🔷 FVG Detection to Radar Conversion Process
The radar does not randomly generate targets.
Every radar diamond begins as a historically detected Fair Value Gap.

Step 1 — Detect
The scanner reviews historical bars across selected lookback.
Bull:
Low(3) > High(1)
Bear:
High(3) < Low(1)

Step 2 — Filter
Detected FVGs are qualified by:
• Minimum gap size
• Tick threshold
• ATR filter (optional)
• Filled / Unfilled condition
Detect

Qualified

Step 3 — Convert
Qualified FVGs are converted into radar coordinates based on:
• Distance from current price
• Gap size
• Bull/Bear type
• Strength rank
• MAX status
FVG Zone

Distance

Ring Placement

Step 4 — Scan
Radar Sweep Logic
The sweep scanner functions as an active liquidity detection and target-priority system.
When sweep overlaps a radar diamond:
SCAN HIT
The radar reveals:
• Bull/Bear type
• Price level
• Distance
• Strength
• MAX status

🔷 R — Reaction
What should traders do next?
• Pullback
• Retest
• Rejection
• Continuation
• Risk management

📘 Usage

🔷 Best For
• FVG traders
• Smart Money Concept traders
• Liquidity sweep traders
• Pullback / retest traders
• Institutional repricing analysis
• Bull versus Bear dominance tracking
• Traders who want a visual map of imbalance above and below current price

🔷 How to Read the Illustration
This illustration shows how the FVG Radar Scanner converts chart-based Fair Value Gaps into a radar-style liquidity map.
снимок
The chart and radar should be read together:
• FVG boxes show the actual imbalance zones on price
• Radar diamonds show where those FVGs are positioned relative to current price
• The sweep highlights nearby or important radar targets
• The info table summarizes bull/bear imbalance, volume, FLOW, and MAX location

🔷 Quick Visual Legend
🟣 Purple FVG Box / Diamond
→ Bearish FVG
→ Premium supply
→ Potential resistance, rejection, or mitigation zone
🔷 Blue FVG Box / Diamond
→ Bullish FVG
→ Discount demand
→ Potential support, pullback defense, or reaction zone
🔶 Gold MAX FVG
→ Largest detected Fair Value Gap
→ Strongest displacement zone in the scan
→ Major retest or reaction candidate
● Current Price
→ Market decision point
→ Center of the current supply-versus-demand battlefield

🔷 Battlefield Reading

In the example image:

• Purple FVGs are positioned above price
• Blue FVGs are stacked below price
• Gold MAX FVG is above current price
• Radar shows a stronger cluster of blue FVGs below the market
• The dashboard shows bull/bear count, volume, FLOW, and MAX price

This means price is trading between overhead premium supply and lower discount demand.

The market is inside a liquidity battlefield:

🟣 ABOVE PRICE
Bearish FVG / Supply
Premium imbalance
Possible resistance



● CURRENT PRICE
Decision zone
Bull/Bear pressure center



🔷 BELOW PRICE
Bullish FVG / Demand
Discount imbalance
Possible support

🔷 FVG Box Retest Framework

FVG boxes are not only visual zones. They are potential retest, mitigation, rejection, or continuation areas.
🔷 Bullish FVG Retest:
When price pulls back into a blue bullish FVG box:
→ Potential discount retest
→ Watch for support, mitigation, reclaim, or continuation
→ If defended, the zone may act as demand
снимок
Price expands upward

Price pulls back

[ 🔷 Bullish FVG Box ]

Hold / Reclaim

Potential continuation upward

🟣Bearish FVG Retest:
When price rallies into a purple bearish FVG box:
→ Potential premium retest
→ Watch for rejection, mitigation, failed reclaim, or continuation lower
→ If rejected, the zone may act as supply
снимок
Price expands downward

Price rallies back

[ 🟣 Bearish FVG Box ]

Reject / Fail

Potential continuation downward

🔶MAX FVG Retest

The gold MAX FVG marks the largest detected imbalance.

If MAX is above price:
снимок
→ Major premium retest candidate
→ Potential resistance
→ Watch for rejection or failed reclaim

If MAX is below price:
снимок
→ Major discount retest candidate
→ Potential support
→ Watch for defense or reclaim

🔷 Sweep + Retest Priority
The sweep scanner adds priority to the radar map.
When the sweep hits an FVG while price is near or retesting that same zone, the setup becomes more important.
Sweep Hit + Bullish FVG Retest
• Sweep detects Bull FVG
• Price pulls into the blue FVG box
→ Potential demand defense zone
Sweep Hit + Bearish FVG Retest
• Sweep detects Bear FVG
• Price rallies into the purple FVG box
→ Potential supply rejection zone
Sweep Hit + MAX FVG
• Sweep detects the gold MAX FVG
→ Highest-priority imbalance zone in the current scan
🔷 Practical Reading Workflow
1. Locate Current Price
First, identify whether price is trading closer to upper bearish FVGs or lower bullish FVGs.
2. Check Nearby FVG Boxes
Look for the closest active FVG zones above and below price.
3. Watch the Radar Blips
Use the radar to see whether imbalance is clustered above price, below price, or balanced on both sides.
4. Monitor Sweep Hits
A SCAN HIT means the radar is actively prioritizing that FVG target.
5. Confirm With Price Action
Use reaction, rejection, reclaim, candle close, BOS / CHoCH, or your confirmation model before making decisions.
🔷 Practical Frameworks
Bullish Framework
Bullish FVG below or near current price
→ Potential discount imbalance
→ Watch for pullback, mitigation, reclaim, or defense
Bearish Framework
Bearish FVG above or near current price
→ Potential premium imbalance
→ Watch for rejection, mitigation, or supply response
Retest Framework
Price returns into an existing FVG box
→ Watch whether imbalance holds, fails, or fully mitigates
Sweep Framework
Sweep hit on nearby FVG
→ Active liquidity awareness
→ Zone becomes short-term priority
MAX Framework
Gold MAX FVG
→ Largest displacement zone
→ Institutional imbalance anchor
→ High-priority retest or reaction candidate
🔷 Decision Model
Box = Zone
Radar = Map
Sweep = Priority
Retest = Decision
Reaction = Confirmation
🔷 Bottom Line
FVG Radar Scanner is designed to help traders move from simple imbalance detection into structured liquidity interpretation.
The boxes show where imbalance exists.
The radar shows where those imbalances sit relative to price.
The sweep highlights which zones deserve attention.
The retest shows whether the market respects or invalidates the imbalance.
