I've always found the most interesting part of the market to be those overlooked details. Recently, I’ve been studying a trading concept called fair value gap, and I think it’s worth going into it in depth.

Simply put, a fair value gap is a “vacuum” left behind when the market experiences rapid swings. Imagine the price suddenly surging or sharply dropping—there will be a region in between where trading activity is very low. This is an imbalance. The market is especially sensitive to this kind of imbalance and will always look for a way to “fill” that gap afterward. The logic is actually pretty intuitive—markets hate vacuums, and will ultimately restore balance again.

How do you find these fair value gaps? The core is to look at price action. When a big candle moves quickly, if it doesn’t overlap with the next candle, a gap forms between them. That gap is what you’re looking for. These are usually easier to spot in trending markets or after sudden news events—especially in volatile markets like crypto or forex. A common pattern is a three-candle setup: the first candle follows the trend, the second creates the gap, and the third continues extending in the same direction, leaving the gap unfilled.

Why is this so important? Because fair value gaps are like magnets for price. Once formed, the market will eventually come back to fill them. These gaps can act as dynamic support or resistance, depending on how you use them. If you can identify high-probability fair value gap and combine them with other technical tools, you can find good trading opportunities.

In real trading, you need patience. Don’t rush into a trade just because you see a gap—wait until the price truly returns to that area, and only act when you see a reversal signal or a breakout of a key level. I typically confirm the validity of a fair value gap using moving averages, trendlines, or Fibonacci retracements. For example, if the gap lines up exactly with the 50% retracement level, the signal is even stronger.

The most important thing is to trade in the direction of the trend. In an uptrend, look for support-type gaps; in a downtrend, look for resistance-type gaps. Entry points should be clear—you can enter on a bounce or breakout within the gap area. Place the stop-loss outside the gap, and set the take-profit at the next key support/resistance level, or based on the expected move size implied by the gap. Risk management is always the top priority—on any single trade, don’t risk more than 1-2% of your account.

I’ve seen a lot of people make mistakes. Some people trade every gap they see, and end up losing frequently. Some ignore the broader market environment and misuse fair value gaps in ranging markets. Others are too impatient and rush in before the price has confirmed. The real winners are the ones who have patience and discipline.

To be honest, mastering the fair value gap tool can give you plenty of advantages. The market is full of inefficiencies, and gaps are the most direct manifestation of that. By combining this concept with other technical analysis, and adding strict risk management, your trading win rate can improve noticeably. Whether you’re a beginner or an experienced trader, this is definitely worth studying in a serious way.
