Fair Value Gaps (FVGs) are among the most widely studied concepts in modern institutional price action education. They represent price imbalances created during rapid directional moves — zones where the market moved too quickly for two-sided participation, leaving behind a structural void that price frequently returns to revisit.
How Fair Value Gaps Form
A Fair Value Gap forms through the interplay of three consecutive candles during a strong directional move:
- Candle 2: The strong impulse candle that creates the displacement.
- Candle 3: The candle after the impulse.
This range represents a price area where, educationally speaking, the market has not yet had a chance to establish two-sided participation.
Why Price Returns to Fill FVGs
The educational rationale for FVG fills draws on several market microstructure concepts:
- Market efficiency: Liquid markets tend to seek two-sided participation over time. Gaps represent areas of inefficiency that the market gravitates toward resolving.
- Order fill completion: Large participants who initiated the impulse move may have unfilled limit orders waiting within the gap zone.
- Structural reference: FVGs frequently coincide with other structural reference points (order blocks, support/resistance), amplifying their analytical significance.
FVGs vs. Regular Support and Resistance
Unlike traditional horizontal support and resistance levels — which are drawn at price areas where the market has repeatedly tested and reacted — FVGs are dynamic zones defined by the specific geometry of the impulse move that created them. They carry a different type of analytical meaning: not "the market respects this level" but rather "the market left unfinished business here."
Timeframe Hierarchy for FVGs
Higher timeframe FVGs carry greater analytical weight:
- Daily FVGs: Represent major institutional imbalances that may take days or weeks to fill. High structural significance.
- 4H FVGs: Intermediate imbalances with significant analytical relevance for multi-day structural context.
- 1H FVGs: Intraday imbalances, often used within kill zone analysis for near-term structural context.
Confluence with Order Blocks
The highest-quality FVG setups in educational analysis occur when the gap zone overlaps with an unmitigated order block — creating a dual zone of potential institutional interest. When higher timeframe structure, an order block, and an FVG align at the same price area, the confluence is studied as a particularly high-quality educational reference point.
