Fair Value Gap (FVG)

A Fair Value Gap (FVG) is a three-candle price imbalance on a candlestick chart where the high of the first candle and the low of the third candle do not overlap, leaving a "gap" in price that often acts as a magnet for future price action.

Quick Definition Box

A Fair Value Gap is a specific price zone created by aggressive institutional order flow, visible as a non-overlapping area between three consecutive candles. It represents an area of inefficiency where price moved too quickly, leaving behind unfilled orders. Traders watch these zones because price frequently returns to "fill" the gap before continuing its original direction.

Detailed Explanation

A Fair Value Gap forms when price moves with such velocity that the trading range of three consecutive candles fails to overlap completely. Specifically, on a bullish FVG, the low of the third candle is higher than the high of the first candle. On a bearish FVG, the high of the third candle is lower than the low of the first candle. This creates a visible "gap" on the chart—not a literal gap in trading (like a weekend gap), but a gap in the overlapping price ranges.

The logic behind FVGs stems from market microstructure. When large institutional orders (e.g., a hedge fund buying 50,000 lots of EUR/USD) hit the market, price moves rapidly. Retail traders and smaller participants are left behind, and their pending orders—stop losses, limit orders, and pending entries—remain unfilled in that price zone. These unfilled orders create a "liquidity void." When price later returns to this zone, it often finds willing counterparties, causing a reaction.

The size of an FVG matters. A small FVG (e.g., 5 pips on EUR/USD) may be filled quickly and ignored. A large FVG (e.g., 30–50 pips on a 15-minute chart) often acts as a significant support or resistance zone. The time frame also matters: FVGs on higher time frames (daily, 4-hour) are considered more significant than those on lower time frames (1-minute, 5-minute) because they represent larger institutional activity.

To identify an FVG precisely, follow these steps on any candlestick chart:

1. Look for three consecutive candles where the middle candle has a large body (often 1.5x or more the average body size).
2. For a bullish FVG: Check if the low of candle 3 is above the high of candle 1. If yes, the FVG zone is from the high of candle 1 to the low of candle 3.
3. For a bearish FVG: Check if the high of candle 3 is below the low of candle 1. The zone is from the low of candle 1 to the high of candle 3.

The zone itself is often drawn as a rectangle or shaded area. Some traders use the midpoint of the FVG as a more precise entry level, while others wait for price to enter the full zone.

Real-World Example

Imagine you are watching a 15-minute chart of USD/JPY. At 10:00 AM, price is at 150.00. Over the next 15 minutes, a strong bullish candle pushes price from 150.00 to 150.40 (candle 1, high = 150.40, low = 150.00). The next candle (candle 2) continues higher, closing at 150.70, with a high of 150.75 and a low of 150.45. The third candle (candle 3) opens at 150.70 and rallies to 151.00, with a low of 150.65.

Now check the overlap: The high of candle 1 is 150.40. The low of candle 3 is 150.65. Since 150.65 > 150.40, there is no overlap. The FVG zone is from 150.40 (high of candle 1) to 150.65 (low of candle 3)—a 25-pip gap.

Price continues to 151.20, then pulls back. Over the next hour, price retraces to 150.50, entering the FVG zone. At this point, many traders might watch for a bullish reaction (e.g., a bullish engulfing candlestick or a rejection wick) because the unfilled buy orders from the initial surge are still resting there. If price fills the entire zone (drops below 150.40), the FVG is considered "filled" and loses its significance.

Why It Matters for Traders

Fair Value Gaps are a core component of price action trading, particularly within the Smart Money Concepts (SMC) methodology. They help traders identify areas where price is likely to react, offering potential entry points with a defined risk (the opposite side of the FVG). For example, a trader might place a buy stop order just above the FVG midpoint, with a stop loss below the FVG low.

FVGs also help in understanding market structure. A series of unfilled FVGs on a daily chart can indicate strong trending conditions. Conversely, when price fills FVGs rapidly, it often signals a weakening trend or a potential reversal.

However, FVGs are not guaranteed reversal points. They are zones of interest, not exact price levels. Price may enter an FVG, bounce, then return and fill it completely before continuing. Traders should combine FVGs with other tools like support/resistance levels, moving averages, or RSI divergence to increase the probability of a valid setup.

Common Misconceptions

Misconception 1: "An FVG is the same as a gap on the chart."
False. A traditional gap (e.g., a weekend gap) shows a complete absence of trading between two price levels. An FVG is a three-candle imbalance where trading occurred, but the ranges did not overlap. Price did trade at every level within the FVG, but the volume was insufficient to create a balanced market.

Misconception 2: "Price always fills an FVG."
Not true. While many FVGs do get filled, especially on lower time frames, some remain unfilled for extended periods, particularly on higher time frames during strong trends. A daily FVG in a powerful bull market may never be touched again.

Misconception 3: "A bigger FVG is always better."
Size matters, but context matters more. A 50-pip FVG on a 5-minute chart during low-liquidity Asian hours is less significant than a 20-pip FVG on a 4-hour chart during London/NY overlap. Always consider the time frame and market session.

How XM Compares

XM provides trading platforms (MT4/MT5) where traders can manually draw FVGs using standard drawing tools like rectangles or trend lines. XM also offers educational webinars and articles that cover price action concepts, including market imbalances, though specific FVG content may vary. XM does not provide automated FVG indicators as part of its standard platform tools, so traders typically rely on manual identification or third-party indicators.
