This article looks at three trading terms that often get mixed up: imbalance, fair value gaps, and order blocks. They’re connected, but they’re not the same thing. Imbalance is simply one side of the market pushing harder than the other. A fair value gap shows where price moved too quickly. An order block highlights where price paused before making a strong move. The goal isn’t to turn these into signals, but to make it easier to read what the chart is actually showing without blending different ideas together.
Fair value gap vs order block vs imbalance is one of those comparisons that keeps coming up once you start paying attention to how price really moves. You see a fast move, a reaction later on, and suddenly everyone is calling it something different.
I’ll make it clear in this article what each one actually refers to, and why they’re not the same thing.
“The market discounts everything.” — Charles Dow
Imbalance is the pressure behind the move. Fair value gaps and order blocks are just different ways that pressure shows up on the chart.
Fair value gaps are about speed and momentum. Order blocks are about where price paused and then made a decision.
None of these concepts work on their own. They’re tools to help read price, not guarantees of what comes next.
In trading, imbalance just means buyers and sellers aren’t evenly matched. One side is pushing harder, so price moves faster instead of drifting back and forth.
That’s when you see sharp moves, long candles, or price jumping through levels. It’s not a setup on its own, just a way to describe when pressure is clearly coming from one side of the market.
An order imbalance is about orders. It happens when there are far more buy orders than sell orders, or the other way around. That mismatch is what creates pressure in the market.
A price imbalance is simply how that pressure shows up on the chart. Price moves too quickly, skips over levels, and leaves areas where very little trading actually happened.
Market structure is built by imbalances. Without them, the price would just drift sideways. Imbalance matters because it explains:
Why price breaks highs or lows instead of stalling
Why some moves are sharp and directional
Why price often comes back to certain areas after a fast move
Imbalance exists in every market, but it doesn’t look the same everywhere.
In forex, there’s no central order book, so traders mostly read imbalance through price action and volume clues. In markets like stocks or futures, it can sometimes be seen more directly because order flow data is available.
What doesn’t change is the effect. When pressure isn’t even:
Price gets pushed in one direction
Price doesn’t move in a smooth, balanced way
A fair value gap in trading is what traders call those moments when price moves so fast that it doesn’t trade cleanly through an area. Instead of stepping through each level, price jumps, and a gap is left behind on the chart.
That gap shows a spot where trading was thin. Price didn’t spend time there, and that’s why traders notice it.
The FVG imbalance zone is simply the price area inside a fair value gap. It marks the range that price moved through too quickly, where buying and selling didn’t balance out.
Traders treat this zone as unfinished business on the chart. Price may come back into it, trade through part of it, or move straight past it. The key point is that it highlights where the move was uneven, not that it guarantees any specific reaction.
A fair value gap forms when price moves with enough force that it doesn’t trade evenly from one level to the next. Instead of overlapping candle by candle, part of that move gets skipped.
On the chart, it usually shows up when:
Price accelerates in one direction
The middle candle of the move is clearly larger
The candles before and after don’t fully overlap
That lack of overlap is what creates the gap traders mark as a fair value gap.
A bullish fair value gap forms during a strong move up. Price pushes higher quickly, leaving a gap below the move where buying pressure was dominant.
A bearish fair value gap forms during a sharp move down. Selling pressure takes over, and price drops fast enough to leave a gap above the move.
The direction of the fair value gap simply reflects which side was in control at that moment.
A fair value gap and an imbalance are related, but they’re not the same thing.
Imbalance describes the condition: one side of the market is stronger than the other.
Fair value gap is one way that imbalance shows up on the chart.
An order block is a price area where the market clearly changed direction after a strong move. Traders use the term to describe zones where a lot of buying or selling seems to have taken place before price pushed away with momentum. It’s not about a single candle doing something special, but about the reaction that comes after.
What makes order blocks interesting is that the price often reacts again when it comes back to those areas. Not always, and not perfectly, but often enough for traders to keep them on the chart as reference zones rather than exact levels.
Order blocks are usually marked by looking at what happened just before a strong move.
In simple terms, traders look for:
A clear move away from an area, not a slow grind
A shift in direction or continuation with strength
The last opposing candle or small cluster of candles before that move
The focus is less on the candle itself and more on what price did afterward. If the price moved away decisively, that area gets attention. If it doesn't, it’s usually ignored.
A bullish order block appears before a strong move up. It’s typically found at the end of a small pullback, where selling pressure fades and buyers step in.
A bearish order block shows up before a sharp move down. It marks an area where buying stalled and selling pressure took over.
The direction of the order block simply reflects which side was in control when price left the area.
Order blocks and traditional support and resistance can look similar on the chart, but they’re not the same idea.
Support and resistance are usually drawn based on repeated reactions over time. Order blocks focus more on where price last made a strong decision. One looks back at multiple touches, the other looks at a key moment of imbalance.
That’s why some traders prefer order blocks. They’re less about drawing lines everywhere, and more about narrowing down zones where price showed intent.
In forex, fair value gaps, order blocks, and imbalance tend to appear in the same parts of the chart, especially during fast or directional moves.
You can tell the difference just by watching how the price moves.
A fair value gap shows up when the price blasts through an area. It moves fast, doesn’t hang around, and barely trades there. It’s all momentum.
An order block is different. The price slows down a bit, maybe pulls back, then takes off. That spot matters because it’s where the price made up its mind.
Both show up on the chart, but they’re pointing to different moments in the move.
The difference in market context comes down to when each one tends to matter most.
A fair value gap usually shows up during momentum. The price is already moving, often strongly, and the gap appears as part of that push. It fits best in trending conditions, when the market is active and flowing in one direction.
An order block is more about structure. It often sits near areas where the market paused, shifted, or made a clear decision before continuing. That makes order blocks easier to place within the broader picture of highs, lows, and directional changes.
So while both can appear during the same move, fair value gaps lean toward momentum, and order blocks lean toward structure.
Imbalance is what sits underneath both ideas. When buying or selling pressure isn’t even, the price has to move. That uneven pressure can push the price so fast that it leaves a fair value gap, or it can force the price to pause and then move away, creating an order block.
So imbalance isn’t a separate pattern on its own here. It’s the reason these zones show up in the first place. Fair value gaps and order blocks are just two different ways that imbalance ends up visible on the chart.
In forex, the price moves fast and clean levels don’t always form. When a strong move happens, it can leave both a fair value gap and an order block in the same area. On the chart, they overlap, so it’s easy to treat them as the same thing.
The confusion also comes from language. Different traders use different terms for similar price behavior, and in forex there’s no central order book to separate things clearly. The result is that fair value gaps and order blocks get mixed up, even though they’re describing different parts of the move.
Fair value gaps, order blocks, and imbalance are all ways traders try to read what the price is doing when the market isn’t moving smoothly. They’re connected, but they’re not the same thing. One points to speed, another to decision, and the other to the pressure behind the move.
Understanding the difference doesn’t make the price predictable, but it does make the chart clearer. When you know what you’re looking at, it’s easier to avoid mixing concepts and misreading what the market is actually showing you.

A fair value gap is about speed. The price moves fast and skips levels. An order block is more about a pause before the price takes off. They can show up in the same area, but they’re pointing to different parts of the move.
Not really. Imbalance is the pressure behind the move. A fair value gap is just how that pressure sometimes shows up on the chart.
No. The price comes back to some of them, ignores others, and sometimes only trades part of the gap. There’s nothing that says they have to be filled.
They can look similar, but they’re drawn for different reasons. Support and resistance come from repeated reactions. Order blocks focus on where the price last made a clear move.
Because forex moves fast and doesn’t always respect clean levels. These ideas help traders explain sharp moves and quick reactions when the price doesn’t move smoothly.
A lot of traders do. Imbalance explains the pressure, fair value gaps show rushed moves, and order blocks highlight decision areas. Used together, they help make sense of what the price is doing.
