FVG Fair Value Gap: The Price Vacuum Between 3 Consecutive Candles

FVG Fair Value Gap: The Price Vacuum Between 3 Consecutive Candles

Look at a rapidly rising candle sequence: the first candle closes at $30,000, the third candle opens at $30,800. Between $30,000 and $30,800, an $800 price range has no candle coverage—the first candle’s high didn’t touch the third candle’s low.

This $800 vacuum zone is an FVG (Fair Value Gap). It tells you one thing: in the process of price jumping from $30,000 to $30,800, the intermediate price range had no trading activity—buyers were too eager, unwilling to wait for price to gradually climb to $30,800.

Core Principles

Point 1: Precise Definition of FVG

Bullish FVG (BISI - Bullish Implied Fair Value Gap): In three consecutive candles, the first candle’s high < the third candle’s low. The price range between the first and third candles has no second candle’s shadow coverage—a price vacuum with no trading activity.

Bearish FVG (SIBI - Bearish Implied Fair Value Gap): In three consecutive candles, the first candle’s low > the third candle’s high. The price range between the first and third candles has no second candle’s shadow coverage—price skipped this range.

The essence of FVG: three candles’ price vacuum = a trace of smart money rushing to execute orders. Normal supply-demand dynamics move price gradually—every penny has trading activity. Only when one side rushes to execute (unwilling to wait for gradual advancement) does price skip intermediate ranges, leaving an FVG.

Point 2: FVG Formation Mechanism

FVG formation requires two conditions:

1. Order volume surge: Smart money suddenly releases a large batch of buy/sell orders, pushing price rapidly.
2. Liquidity vacuum: The intermediate price range lacks sufficient opposing orders to absorb the push—neither buyers nor sellers have limit orders at these intermediate levels.

Crypto FVGs are more common than in traditional markets—because crypto liquidity is thinner, with fewer limit orders at intermediate levels. When smart money releases large orders in a thin-liquidity environment, skipping intermediate prices is easier, creating larger FVGs.

Point 3: FVG’s Fill Tendency

FVGs have an important statistical characteristic: price tends to return to FVG zones. Reasons:

1. Information completion: The FVG zone has no historical trading data—price “has no story” in that range. When price later returns to the FVG, the market needs to “complete the information” (execute trades, forming trading data).
2. Smart money balancing: Smart money rushed to execute, leaving an FVG, but rushing means position building/distribution wasn’t refined—smart money may need to return to the FVG zone to fine-tune positions.
3. Technical retracement: After rapid moves, price usually has technical pullbacks—retracements naturally return to FVG zones (because FVGs are vacuums from rapid moves, pullbacks gravitate to nearest vacuum zones).

Note: fill tendency is statistical, not deterministic. Not every FVG gets filled—some FVG price ranges are never revisited (because the trend is so strong, price never retraces to that level).

Point 4: FVG as Entry Assistance Tool

FVG isn’t a standalone entry signal—it’s an entry location assistance tool. It tells you where price might pause (filling FVG), but direction and timing need confirmation from other tools:

• Structure confirmation: In uptrend, bullish FVG fill is a long entry opportunity; in downtrend, bearish FVG fill is a short entry opportunity
• OB confirmation: When FVG and OB overlap in the same zone, entry is more reliable—both point to smart money acting in this area
• Liquidity Sweep confirmation: Sweep then price returns to FVG zone = smart money fine-tuning positions after sweeping stops = more reliable entry timing

Point 5: FVG Invalidation Criteria

FVG invalidation conditions:

• Price fully passes through FVG and continues—fill expectation no longer holds
• FVG has been filled multiple times with diminishing power—each fill consumes the FVG’s information demand
• Price doesn’t continue in FVG’s direction after formation—may not be smart money urgency, just one-time fluctuation

Crypto Applications

BTC Bullish FVG Example.

During BTC’s rapid rise from $28,000 to $31,000:

• Candle 1: high $28,500
• Candle 2: rises from $28,500 to $30,200 (fast bullish candle)
• Candle 3: low $30,800
• FVG range: uncovered price between $28,500-$30,800

This FVG is approximately $2,300 wide—no trading in a $2,300 range, indicating very eager buyers. Later BTC retraces to $29,500-$30,500 entering the FVG zone → long entry point.

ETH Bearish FVG Example.

During ETH’s rapid decline from $2,000 to $1,700:

• Candle 1: low $1,980
• Candle 2: falls from $1,980 to $1,780 (fast bearish candle)
• Candle 3: high $1,750
• FVG range: uncovered price between $1,750-$1,980

This FVG is approximately $230 wide—price skipped $230 with no trading. Later ETH bounces to $1,800-$1,900 entering FVG zone → short entry point.

Special Considerations for Crypto FVGs.

Crypto FVG widths are larger than traditional markets—because volatility is higher and liquidity is thinner. BTC daily candle FVGs may be $500-$2,000 wide, while traditional stock daily FVGs might be only $1-$5 wide. Wide FVGs provide larger entry zones, but also mean wider stop-loss distances. When choosing FVG entry positions, prioritize FVG edges (near OB positions) rather than FVG centers.

Practical Scenarios

Scenario 1: Daily FVG Marking Routine

After every rapid price move, check for FVG formation:

1. Find rapid-move candle sequences (3 candles with movement exceeding recent average)
2. Check whether gaps exist between first candle’s high/low and third candle’s low/high
3. If gap exists → mark FVG range
4. Assess FVG strength (width, subsequent BOS confirmation, OB overlap degree)

Only mark FVGs overlapping with OBs or near key structural positions—FVGs at random locations are mostly noise.

Scenario 2: Entry at FVG + OB Overlap Zones

When FVG and OB overlap in the same price range, this overlap zone is the most reliable entry position:

Long entry:

• Entry position: near lower edge of bullish FVG + near lower boundary of bullish OB (overlap zone’s lowest point)
• Stop-loss position: 0.5%-1% below overlap zone (or below nearest SSL)
• Target position: next BSL zone or next supply zone

Short entry:

• Entry position: near upper edge of bearish FVG + near upper boundary of bearish OB (overlap zone’s highest point)
• Stop-loss position: 0.5%-1% above overlap zone (or above nearest BSL)
• Target position: next SSL zone or next demand zone

Overlap zones are more reliable because two independent smart money traces point to the same location—signal credibility doubles.

Scenario 3: Partial Fill vs Full Fill

FVG filling has two forms:

• Partial fill: price returns to FVG zone but only fills a portion (doesn’t touch the full FVG width). Partial fill is a stronger signal—because smart money only needs to fine-tune positions, not return to the FVG’s starting point.
• Full fill: price passes completely through the FVG zone. Full fill may mean the FVG’s information demand has been satisfied—FVG power has been consumed.

Prioritize entry on partial fills—price touches the FVG edge and reverses, indicating smart money’s power remains effective in the FVG zone.

Common Misapplications

Misapplication 1: Entering at every FVG. Not every FVG is an entry opportunity—only FVGs overlapping with OBs or at key structural positions are worth trading. FVGs at random locations may just be traces from normal fluctuation without deep smart money intent.

Misapplication 2: Expecting every FVG to fill. Fill tendency is statistical—approximately 60%-70% of significant FVGs are partially filled, but not 100%. Some FVG price ranges are never revisited. In strong trends, price may move forward without looking back—waiting for FVG fills may cause you to miss the trend.

Misapplication 3: Entering at FVG center rather than edges. The FVG center is the most dangerous entry position—because stop-loss distance is large (far from FVG edges), and the FVG center lacks OB and other confirmation signals. Edge entries have smaller stop-loss distances and OB confirmation, yielding better risk-reward ratios.

Summary

FVG is the price vacuum zone between three consecutive candles—smart money’s speed trace from rushing to execute orders. Its core characteristic is fill tendency—price tends to return to FVG zones to complete information and fine-tune positions.

FVG isn’t a standalone entry signal—it becomes reliable entry assistance only when overlapping with OBs or appearing at key structural positions. OB marks smart money’s entry range; FVG marks smart money’s speed trace. When they overlap = double confirmation.

Entry position choice: prioritize FVG edges (near OB positions) for entry, with stop-loss outside the sweep’s extreme point. Partial fills are more reliable than full fills—price touching FVG edge and reversing indicates smart money power remains effective in the FVG zone.

FVG is SMC’s most precise positioning tool—it lets you narrow entry positions within OB ranges, from “zone” precision to “specific location within a zone.”
