Gap Trading: What's the Strategy Behind Playing the Gap?

In the ever-evolving world of financial markets, traders are always on the lookout for opportunities to gain an edge and secure profits. One such strategy that has gained popularity over the years is "Gap Trading." Disruptions in stock patterns, known as gaps, can offer a window for astute traders to capitalize on price differentials. In this article, we will delve into the strategy behind playing the gap and how you can employ it to your advantage.

Gap Basics

First and foremost, it's crucial to understand what gaps are. Gaps are distinct price discontinuities on a stock or financial instrument's chart, where the price moves significantly up or down with little to no trading occurring in between. These gaps disrupt the normal price pattern and create opportunities for traders.

Gaps can be triggered by a variety of factors, both fundamental and technical. For instance, if a company announces earnings far above expectations, the stock may gap up, opening at a higher price than it closed the previous day. In the foreign exchange market, a significant news event can widen the bid-ask spread, causing a visible gap on the chart. Additionally, automated program trading, driven by algorithms, can play a role in creating gaps, especially when certain technical levels are breached.

There are four primary types of gaps:

  1. Breakaway Gaps: These occur at the end of a price pattern and signal the beginning of a new trend.

  2. Exhaustion Gaps: These gaps appear near the end of a price pattern and indicate a final attempt to reach new highs or lows.

  3. Common Gaps: These gaps do not fit into any specific price pattern; they represent areas where the price has gapped.

  4. Continuation Gaps: Also known as runaway gaps, these gaps emerge in the middle of a price pattern and signal a surge of buyers or sellers who share a common belief in the stock's future direction.

To Fill or Not to Fill

One of the critical considerations when dealing with gaps is whether they will be filled or not. When we say a gap is "filled," it means that the price has retraced back to the original pre-gap level. Whether or not a gap is filled depends on several factors:

  1. Irrational Exuberance: Gaps can be fueled by overly optimistic or pessimistic market sentiment, which may invite a correction.

  2. Technical Resistance: Sharp price movements often leave behind no immediate support or resistance levels.

  3. Price Pattern: The type of gap, be it exhaustion, continuation, or breakaway, can provide clues about whether it is likely to be filled or not.

When gaps are filled on the same trading day they occur, it is known as "fading." Traders often employ this strategy when they anticipate gaps created by short-term market irrationality, such as during earnings season.

How to Play the Gaps

Now that we understand the basics of gaps and their potential to be filled, let's explore how to play them effectively. There are several strategies traders employ:

  1. Gap Trading: Some traders buy or sell based on fundamental or technical factors that favor a gap on the next trading day. For example, buying a stock after hours following a positive earnings report, anticipating a gap up on the following trading day.

  2. Fading the Gap: Traders may fade gaps by trading in the opposite direction once a high or low point has been determined through technical analysis. For instance, if a stock gaps up on speculative news, experienced traders might short the stock when they believe the gap is unsustainable.

  3. Gap Filling: Traders can wait for a gap to be filled and then buy when the price reaches the prior support or resistance level. This approach is often used when traders anticipate that a gap will be retraced.

Key Considerations

There are a few key points to keep in mind when trading gaps:

Gap Trading Example

Let's look at an example of gap trading with the daily chart of Apple Inc. (AAPL). In the chart, we can identify several gaps, each providing opportunities for traders to enter and exit positions. Gaps can indicate reversals, exhaustion, or continuation of trends, making them valuable for traders looking to capitalize on short-term price movements.

In summary, gap trading is a valuable strategy for traders looking to seize opportunities presented by disruptions in normal price patterns. Gaps can offer quick profits, but they also require careful analysis and risk management. Whether you choose to play the gap by trading in the direction of the gap, fading it, or waiting for it to fill, a sound understanding of gap dynamics is essential to succeed in this strategy. Keep a close watch on price patterns, volume, and the broader market context, and you'll be better equipped to navigate the world of gap trading.
