Fair Value Gaps (FVG): The Ultimate Guide to Imbalance Trading

Price action is rarely perfectly delivered. When the big dogs (central banks and massive institutions) enter the market, they often move price so fast that they leave a "hole" behind. In the world of ICT and Smart Money Concepts (SMC), this hole is known as a Fair Value Gap (FVG).

Understanding FVGs is like having a map of where the market must go next. In this 1200+ word definitive guide, we will explore the mechanics of the FVG, why they exist, and how you can use them to find some of the highest-precision entries in the Forex market.

What is a Fair Value Gap?

A Fair Value Gap is a three-candle sequence that represents an imbalance in price delivery. It occurs when a single candle moves so aggressively that the high of the candle before it and the low of the candle after it do not touch.

The Technical Anatomy

Imagine three candles in a bearish move:

Candle 1: A normal down-close candle.
Candle 2: A massive expansion candle downward.
Candle 3: A normal down-close candle.

If the low of Candle 1 and the high of Candle 3 do not overlap, the empty space within the body of Candle 2 is the Fair Value Gap. This area represents "unfair" delivery—meaning only sellers were active, and the market algorithm needs to eventually return to this zone to offer the price back to buyers.

The Philosophy of the Imbalance

The Interbank Price Delivery Algorithm (IPDA) has one goal: Efficiency. The market wants to be efficient by matching every buy order with a sell order at every price level.

When a "Smart Money" entity wants to sell $500 million of EUR/USD instantly, they create a "Sellers-Only" zone. The price drops through several pips without any buyers being able to participate. Because this is inefficient, the algorithm marks this area. Think of it like a "debt" that the market owes. Eventually, the market will retrace to "repay" that debt by allowing buyers to participate in that zone.

The Three States of an FVG

To trade FVGs professionally, you must understand their lifecycle:

1. The Creation (The Imbalance)

This is when the gap is first formed. It signals that the "Smart Money" has entered the market with power. The length of the middle candle (the expansion candle) tells you the strength of the move.

2. The Mitigation (Filling the Gap)

Price returns to the gap. It doesn't always fill the entire gap. Often, it will hit the Consequent Encroachment (CE)—the 50% level of the FVG—and then reverse. If price fills 100% of the gap, it is considered "fully balanced."

3. The Invalidation

If price closes a candle body through the FVG, the gap is "dead." It no longer serves as a point of interest, and the order flow has likely shifted.

High-Probability FVG Types

Not all gaps are equal. At KTTRFX, we prioritize these three variations:

1. Breakaway Gap

This FVG is formed right after a Liquidity Sweep. It "breaks away" from the range. These are the most powerful FVGs because they represent the start of a major expansion. Institutional traders often never allow these to be fully filled.

2. Measuring Gap

A Measuring Gap is found in the middle of a move. It tells you that the trend is healthy and is likely to continue for a significant distance.

3. Exhaustion Gap

This FVG appears at the very end of a trend. If price enters an exhaustion gap and stays there (closes body candles inside), it’s a signal that the move is over and a reversal is imminent.

How to Trade Using Fair Value Gaps

There are two primary ways to use FVGs in your strategy:

Method A: The Entry Trigger

Once you have your HTF Bias and price has swept liquidity, you wait for displacement. That displacement will create an FVG. You set your "Limit Order" at the start of the FVG or at the 50% level (CE).

Method B: The Target (The 'Magnet')

If you are already in a trade, FVGs on the Higher Timeframe (HTF) act as your targets. The market wants to go there. If you are long and see a Daily Bearish FVG above you, that is where you should look to take your profits.

Consequent Encroachment: The 50% Rule

In ICT, the 50% level of a Fair Value Gap is called Consequent Encroachment (CE).

The Theory: A strong, healthy trend often only needs to fill 50% of an FVG to find the liquidity it needs to continue.
The Execution: If you want to be conservative, place your entry at the start of the FVG. If you want a better Risk-Reward ratio, place your entry at the CE.

If price spends too much time beyond the CE (e.g., several 1-minute candle closes), it's a sign that the gap might not hold and you should consider tightening your stop loss.

Combining FVG with Order Blocks

The "Holy Grail" of ICT entries is the OB + FVG Confluence. When an Order Block and a Fair Value Gap are at the same price level, it creates a "High-Probability Zone." The Order Block represents the intent of the move, and the FVG represents the inefficiency that needs to be filled. When price taps into this zone, the reaction is often explosive.

Common Mistakes Beginners Make With FVGs

Ignoring Market Structure: You see a Bullish FVG and buy. But the market is in a massive crash. The FVG will act as a "speed bump," not a reversal. Always trade in the direction of the BOS (Break of Structure).
Using 'Small' Gaps: Many beginners mark tiny 1-pip gaps. These are noise. Focus on "Visible" gaps that look obvious on the chart.
Entering Without a Liquidity Sweep: An FVG generated "in space" (without taking out a high or low first) is much more likely to fail.

Summary: Trading the Gaps of the Giants

Fair Value Gaps are the "Gasoline" of the market. They show where the algorithm moved too fast and where it must return to balance itself. By learning to identify and trust these zones, you stop chasing price and start waiting for it to come to you.

It takes practice to trust an FVG. Your human brain will tell you "Price is crashing! Why are you buying?!" but as an institutional trader, you know that price is just returning to fair value. If you want to see how we use FVGs to catch 1:10 RR trades every week, join our Academy.

Frequently Asked Questions (FAQ)

Q: Do FVGs have to be filled immediately? A: No. Some FVGs (specifically on Daily or Weekly charts) can stay open for weeks or even months. However, the market will eventually return to them.

Q: What is a 'Sibi' and 'Bisi'? A: These are ICT technical terms. SIBI (Sell Imbalance Buy Inefficiency) is a bearish FVG. BISI (Buy Imbalance Sell Inefficiency) is a bullish FVG.

Q: Can I use FVGs on the 1-minute chart? A: Yes. We use 1-minute FVGs for "Surgical Entries" once price has reached a 15-minute or 1-hour Point of Interest (POI).

Q: How do I draw an FVG on TradingView? A: Most traders use the "Rectangle" tool. Draw from the Low of Candle 1 to the High of Candle 3.
