Fair value gaps, imbalance & liquidity

Section 1 — Problem

Fair value gap trading chatter is everywhere: screenshots, rules, and rigid checklists. Strip the noise and you are really asking about price imbalance—a slice of the tape where the auction did not match much two-sided flow—and often a liquidity imbalance before or during that move: someone needed size, and the chart skipped a pocket to get it.

You scroll the chart and see price jump: one or two aggressive candles leave a naked pocket—almost no overlap between bodies—where the market never really traded. Books and forums call it a “fair value gap” or “imbalance,” and the next question hits immediately: why did it move so fast through that thin air? Did value really teleport, or did something else happen first?

Then the second frustration: half the internet says “price must return to fill the gap,” the other half says “trade the gap as support,” and your own experience says sometimes it fills, sometimes it never looks back. Without a cycle lens, you are left pattern-matching letters on candles instead of reading who needed liquidity and when.

Section 2 — What is a fair value gap?

In plain terms, a fair value gap (often shortened to FVG) describes a stretch of price action where the auction left a thinly traded band: aggressive buying or selling skipped across a slice of the prior range so quickly that limit orders in the middle were not matched in sequence. Visually it is the empty corridor between the wicks or bodies of neighbouring candles—the “gap” in continuity, not necessarily a Monday-open gap on a daily chart.

Traders also call this price imbalance or a liquidity void: the idea is the same. The market did not “agree” on a fair price inside that band in that moment; one side lifted offers or hit bids so fast that the micro-structure looks inefficient. Whether it gets “filled” later is an empirical question—it often matters for mean reversion when larger participants are happy to recycle inventory through that band, but it is not a law of physics.

Section 3 — What’s actually happening (AMD lens)

In the AMD framework Martin Cole documented—Accumulation, Manipulation, Distribution (with distribution also described as profit release)—most of the violent, one-directional pushes that leave imbalance footprints sit closest to Manipulation and the hand-off into the next phase. Manipulation is where the crowd's resting liquidity is located and used: stops beyond obvious highs and lows, breakout orders stacked at the wrong edge of the range, belief pressed until it breaks. A sharp leg that prints an FVG is often the signature of that liquidity being taken so the auction can continue with less opposition—not “random volatility.”

Accumulation is the quieter work of building or distributing inventory before the obvious trend; you may still see small imbalances, but the dramatic voids traders obsess over tend to appear when the game shifts from positioning to testing and harvesting. Distribution (profit release) is where the accumulated edge is worked off into the wider market—what looks like a trend leg on your chart can be release, not a standalone imbalance strategy.

The same story is unpacked in the manipulation cluster: liquidity grabs vs breakouts, stop loss hunting, buffer zones & stop-taking, and seeing market manipulation without conspiracy. FVG vocabulary is just another window on that same liquidity arc—useful when you keep AMD as the frame.

Section 4 — How to recognise it on a chart

You are looking for fast, directional candles (or sequences) where the wicks fail to overlap much of the prior bar's real body or range, leaving a clear rectangular void on the timeframe you are trading. On lower timeframes the pattern is common around news, session opens, or right after a level breaks—precisely when stops and resting orders are dense.

Context beats geometry: ask whether the void formed after a crowded level was taken (stops triggered, breakout traders committed) or whether it opened in thin air with no prior liquidity story. The first case lines up with the manipulation toolkit— support and resistance as belief zones is the companion read for where those voids tend to originate.

Return to fill is worth treating as a behaviour, not a promise: price may revisit the band to close the visual gap because unfinished business attracts mean reversion, or because larger traders are comfortable trading two-sided flow there. If the broader phase has moved on, the chart can leave imbalances behind like scar tissue. Your job is to read phase and conviction, not to collect every box the indicator community draws.

Section 5 — How PAT relates

PAT does not exist to paint textbook FVG rectangles on every spike. It exists to show AMD-relevant structure on TradingView—where belief is building, where it is under stress, and where size shows up—so you are not trading a meme pattern in isolation. The full cycle is in What Is the AMD Indicator?. How each visual layer maps to the chart is in PAT: the five visual elements—buffers and pressure sit closest to the manipulation story behind many imbalances; rays and the floating zone help you see whether the void happened from a mature part of the cycle or from thin noise.

For practical sequencing—how to read setups, risk, and integration—work through the PAT manual. When you already understand liquidity grabs and buffer zones from the training videos, PAT is the layer that keeps you aligned with structure behind the move instead of chasing every unfilled box.

Section 6 — Summary

Takeaway: a fair value gap is a liquidity and auction story—a slice of price that traded too fast for orderly two-sided matching—not a guaranteed magnet. Read it inside Accumulation, Manipulation, Distribution, tie it to the same manipulation cluster lessons you already have on this site, and use PAT to ask whether the market is still interested in that unfinished business—or has already moved the game forward.
