Financial markets do not always move smoothly. At times, price can move so aggressively in one direction that certain areas of the chart are traded through very quickly with little interaction between buyers and sellers.
In price action trading, these fast-moving areas are often referred to as fair value gaps, or FVGs.
The idea behind a fair value gap is that the market moved too quickly through a price area, creating an imbalance between buying and selling activity. Because of this imbalance, traders often monitor whether price later returns to that area before continuing in the original direction.
Today, we will explain what fair value gaps are, why they form and how traders use them when analysing potential entries and market structure.
What Is a Fair Value Gap?
A fair value gap is an area on the chart where price moves aggressively in one direction, leaving very little trading activity between two price levels. This usually happens during strong momentum conditions where buying or selling pressure becomes highly imbalanced.
For example, during a rapid upward move, price may move through an area so quickly that there is very little overlap between surrounding price movements. Traders who use fair value gap analysis view this as a temporary imbalance within the market.
The same concept can also occur during strong downward moves.
Why Fair Value Gaps Form
Fair value gaps are generally created when market momentum increases suddenly. This can happen during major economic news releases, breakout moves, periods of increased volatility or strong institutional activity.
When buying or selling pressure becomes aggressive enough, price may move rapidly through certain levels without spending much time trading there. Some traders believe the market later revisits these areas because price seeks to rebalance the inefficiency created during the fast move.
Why Traders Watch Fair Value Gaps
Many traders monitor fair value gaps because price will often retrace back into these areas before continuing in the original direction.
For example, after a strong upward move creates an imbalance, traders may watch for price to revisit the gap before looking for signs of renewed buying pressure.
This is why fair value gaps are sometimes described as acting like magnets within the market. However, this does not mean every gap will be revisited or respected perfectly. Some imbalances remain unfilled while others lose significance as market conditions change.
Using Fair Value Gaps With Market Structure
Fair value gaps are rarely used completely on their own. Many traders combine them with broader market concepts such as:
- Trend direction
- Support and resistance
- Liquidity areas
- Order blocks
- Price action confirmation
For example, a fair value gap forming alongside a strong trend and a key support area may attract more attention than a gap appearing during choppy market conditions.
This context helps traders assess whether the imbalance remains relevant within the current market structure.
The Difference Between Gaps and Traditional Price Gaps
Fair value gaps are slightly different from traditional gaps often seen in stock markets. A traditional gap usually appears when the market opens significantly higher or lower than the previous closing price.
Fair value gaps, however, are based more on the speed and imbalance of price movement within the chart itself rather than on a market opening difference. This is why fair value gaps are commonly discussed within forex and intraday trading where traditional opening gaps are less common.
Why Not Every Gap Is Important
One common mistake is assuming every imbalance will lead to a strong reaction. In reality, some fair value gaps are more significant than others.
Gaps created during strong momentum or around important market levels often attract more attention than smaller imbalances formed during quiet conditions. This is why traders usually focus more on the overall market context rather than treating every gap as a high-probability setup.
Understanding Market Inefficiency
The idea behind fair value gaps is linked to market efficiency. When markets move gradually, buying and selling activity tends to remain relatively balanced. During aggressive moves, however, that balance can temporarily break down as one side overwhelms the other.
Fair value gaps attempt to identify these moments where price moved too quickly for the market to trade efficiently through every level.
Conclusion
Fair value gaps are areas where price moves aggressively enough to create temporary imbalances within the market.
By identifying these zones and analysing how price reacts when revisiting them, traders can develop a deeper understanding of momentum, liquidity and market structure.
At Samuel and Co Trading, concepts such as fair value gaps form part of understanding how fast-moving markets create areas of imbalance that may later influence future price movement.
In trading, the speed of a move can sometimes reveal just as much as the direction itself.
