Imbalances and Fair Value Gaps, Displacement

What an Imbalance Actually Is

Most of the time, price moves in a relatively orderly way — each candle's range overlaps somewhat with the candle before and after it, meaning both buyers and sellers had a chance to transact at most prices in that zone. An imbalance happens when that overlap breaks down: price moves so fast in one direction that a range of prices gets skipped over almost entirely, with very little two-sided trading happening there.

This matters because a level with almost no trading history is a level with almost no resting orders. It's the opposite of the liquidity pools from the last lesson — instead of a crowded area, it's an empty one. And empty areas tend to get "filled in" later, because the market has an tendency to revisit places where a two-sided auction never really happened.

Fair Value Gap (FVG): The Three-Candle Definition

The most common and precise way to define an imbalance is the Fair Value Gap (FVG), built from three consecutive candles:

• Bullish FVG: the high of candle 1 is below the low of candle 3. The gap between candle 1's high and candle 3's low is the FVG — a zone candle 2 blew through so fast that no trading occurred there on the way.
• Bearish FVG: the low of candle 1 is above the high of candle 3. The gap between candle 1's low and candle 3's high is the FVG.

The middle candle (candle 2) is the one doing the damage — it's the large, often wick-less candle that creates the imbalance by moving further and faster than the candles around it.

Displacement: The Cause of the Gap

Displacement is the aggressive, high-momentum move that creates a fair value gap in the first place. It's usually a candle (or short sequence of candles) with an unusually large body relative to recent candles, minimal wicks, and a fast close. Displacement is the market signaling urgency — one side is no longer patiently working an order, they're taking liquidity aggressively to get a position on before price moves further away from them.

Displacement matters because it's a stronger signal than an ordinary breakout. An ordinary break of a level can happen slowly, on light participation. Displacement candles typically show real conviction — enough that they leave an unfilled gap behind them. When you see displacement paired with a break of structure (from lesson two), that combination is one of the more reliable tells that a real shift in control just occurred, not just a probe.

Why Gaps Get Revisited

Because an FVG represents a price zone with a thin order book, it often acts like a magnet later — not because of any rule that "gaps must fill," but because thin zones offer efficient entries for anyone who wants to trade in the direction the displacement was going. A pullback into an FVG, followed by a resumption of the original direction, is one of the most common and well-documented ways these zones get used by structured traders as an entry area, rather than chasing the displacement candle itself.

Not every gap gets filled quickly, and not every gap needs to fill completely before price moves on. Treat the FVG as a zone of interest, not a guaranteed destination.

Worked Example

Say ES prints three consecutive 5-minute candles: Candle 1 has a high of 5,905.00. Candle 2 is a large bullish displacement candle, opening at 5,906.00 and closing at 5,924.00 with almost no wick. Candle 3 has a low of 5,919.00.

Because candle 1's high (5,905.00) is below candle 3's low (5,919.00), there's a bullish FVG spanning 5,905.00 to 5,919.00 — a 14-point zone that got skipped over by candle 2's displacement move.

A structured trader watching this doesn't chase price at 5,924. They note the displacement (candle 2's size and lack of wick signals real conviction), mark the FVG zone from 5,905 to 5,919, and treat a future pullback into that zone — assuming structure elsewhere still supports the bullish read — as a hypothetical area to study for a long entry with a defined invalidation below the zone, rather than a certainty.

Keeping This in Perspective

FVGs and displacement are tools for locating where an entry might make sense within an existing structural bias — not a standalone signal. A gap in a chart with no clear structure, no liquidity context, and no trend bias is just a gap. Combine it with what you learned in lessons two through four before treating it as decision-relevant.
