Fair Value Gaps, Displacement and Imbalances

Three-candle gaps, impulsive moves, partial fills and failed imbalances.

Educational notice: This material is for learning, not financial advice. Leveraged trading involves significant risk.

Identify a three-candle FVG

A bullish fair value gap is often drawn when the first candle high sits below the third candle low in a strong three-candle sequence. A bearish version occurs when the first candle low is above the third candle high. This identifies a chart-defined interval with limited overlap, not a guarantee that unfilled institutional orders remain there. Check the actual high and low boundaries.

Displacement is contextual

Displacement refers to an unusually strong directional move relative to nearby candles. Compare candle bodies, range, overlap and volatility; a large candle during a news release can mean something different from one during quiet trading. A move becomes more analytically interesting when it also changes a clearly marked structure level. Large candles alone are not a reliable entry model.

Fills and invalidation

Price can revisit part of an imbalance, fill it completely, trade through it or never return. Some traders monitor the midpoint, sometimes called consequent encroachment, but a midpoint is a reference level rather than a universal support or resistance. Define whether the setup is invalidated by a full close through the zone or by loss of the related swing structure.

Worked chart example

Imagine candle one has a high of 1.1000, candle two rallies sharply, and candle three has a low of 1.1012. The interval from 1.1000 to 1.1012 is a bullish FVG by this definition. Price later retraces to 1.1006 and bounces. Record the reaction and subsequent outcome, including examples where the same pattern fails, instead of counting only successful charts.

A repeatable chart-study method

For a three-candle bullish fair-value gap, define the gap between the first candle high and the third candle low only when the latter exceeds the former. If those prices are 1.0810 and 1.0816, the six-pip interval is a chart-based gap under that convention. It does not establish that every price inside the interval had zero transactions.

Practice exercise and review questions

Displacement should be measured rather than judged only by candle appearance. One possible measure is body size divided by the average true range from the prior fourteen completed bars. A large ratio during a major release may reflect sudden repricing rather than durable directional demand. Keep the indicator window fixed across examples.

Common mistakes and limitations

Test whether the first return into a gap differs from later returns and whether the gap is fully filled, partly filled or never revisited within a defined number of bars. Include cases in which price crosses the entire region without reaction. A stop and target chosen only after observing the bounce cannot support a credible backtest.

Compare alternative explanations

A three-candle gap does not show a literal absence of transactions in spot FX. It is a chart-defined price interval. Compare gaps that fill quickly with those that fail, and control for volatility around scheduled data releases.

Risk and responsible application

For a bullish gap from 1.1000 to 1.1020, define whether entry is at the upper edge, midpoint or lower edge before testing. A stop must reflect structural invalidation rather than the mere existence of the 20-pip interval.

Lesson checkpoint

Independent review: Fair Value Gaps, Displacement and Imbalances

For fair value gaps, displacement and imbalances, start with the distinction between “Identify a three-candle FVG” and “Displacement is contextual”. Record what can be observed directly in the data or chart before adding a causal interpretation. Write down the timeframe, instrument and the point in time at which the evidence became available.

For fair value gaps, displacement and imbalances, next revisit “Fills and invalidation”. Build two competing explanations for the same observation, then identify the additional observation that would distinguish them. Avoid assuming that a visual pattern reveals the intentions of unseen market participants.

Your review of fair value gaps, displacement and imbalances should include one historical example that fits the lesson definition and one that appears similar but fails an essential condition. Save both examples with the same measurement rules. If the classification changes when the chart is viewed without future candles, record that limitation rather than discarding the example.

Applied analysis: testing the lesson in context

The following exercise develops the specific decisions involved in fair value gaps, displacement and imbalances. It is a hypothetical training workflow, not a prediction or an instruction to place a live trade. Keep the market, time zone, instrument, observation window and data source fixed before evaluating the idea. Separate what the chart shows from the interpretation assigned to it; two analysts can label the same sequence differently without either label being a verified market mechanism.

Case step 1: Identify a three-candle FVG

Start with the lesson's identify a three-candle fvg component. Source observation: A bullish fair value gap is often drawn when the first candle high sits below the third candle low in a strong three-candle sequence. A bearish version occurs when the first candle low is above the third candle high. Record the exact candle or pivot at which this information first became available. If confirmation depends on a later close, mark that later close as the earliest legitimate decision point. A visually compelling retrospective drawing is not sufficient evidence that the setup was identifiable in real time.

Now construct a counterexample for identify a three-candle fvg: imagine the price initially behaves as the lesson suggests but then fails to follow through. Write the invalidation condition as an observable price or time event, not as a vague change in confidence. Compare two annotated screenshots, one before the proposed confirmation and one after it. Explain what genuinely changed in the available evidence. For a trading-system study, record spread, slippage, position size, and whether the proposed stop could have been filled at the assumed price.

Case step 2: Displacement is contextual

Start with the lesson's displacement is contextual component. Source observation: Displacement refers to an unusually strong directional move relative to nearby candles. Compare candle bodies, range, overlap and volatility; a large candle during a news release can mean something different from one during quiet trading. Record the exact candle or pivot at which this information first became available. If confirmation depends on a later close, mark that later close as the earliest legitimate decision point. A visually compelling retrospective drawing is not sufficient evidence that the setup was identifiable in real time.

Now construct a counterexample for displacement is contextual: imagine the price initially behaves as the lesson suggests but then fails to follow through. Write the invalidation condition as an observable price or time event, not as a vague change in confidence. Compare two annotated screenshots, one before the proposed confirmation and one after it. Explain what genuinely changed in the available evidence. For a trading-system study, record spread, slippage, position size, and whether the proposed stop could have been filled at the assumed price.

Case step 3: Fills and invalidation

Start with the lesson's fills and invalidation component. Source observation: Price can revisit part of an imbalance, fill it completely, trade through it or never return. Some traders monitor the midpoint, sometimes called consequent encroachment, but a midpoint is a reference level rather than a universal support or resistance. Record the exact candle or pivot at which this information first became available. If confirmation depends on a later close, mark that later close as the earliest legitimate decision point. A visually compelling retrospective drawing is not sufficient evidence that the setup was identifiable in real time.

Now construct a counterexample for fills and invalidation: imagine the price initially behaves as the lesson suggests but then fails to follow through. Write the invalidation condition as an observable price or time event, not as a vague change in confidence. Compare two annotated screenshots, one before the proposed confirmation and one after it. Explain what genuinely changed in the available evidence. For a trading-system study, record spread, slippage, position size, and whether the proposed stop could have been filled at the assumed price.

Evidence record and independent assessment

Create a small research log specifically labelled “Fair Value Gaps, Displacement and Imbalances”. For each candidate observation, store its date, instrument, session, timeframe, setup definition, entry eligibility, invalidation level, expected costs, and actual subsequent path. Include candidates that never triggered, rather than selecting only attractive examples. Compare at least two market regimes and note whether the interpretation changes when a nearby swing anchor or session boundary is chosen. If it does, classify the result as sensitive to analyst discretion rather than robust evidence.

Finally, write a three-part conclusion about fair value gaps, displacement and imbalances: (1) which elements can be verified directly from historical prices, (2) which elements are hypotheses about participants or future behavior, and (3) what observation would cause you to reject the hypothesis. The exercise is complete only when a second reader could reproduce your markings using the written rules. Do not infer a profitable edge from a single worked example; that requires a separately designed, cost-aware and out-of-sample evaluation.
