Gap Trading Strategies

What is a Price Gap?

A price gap is an area on a chart where no trading occurred. It happens when a stock's opening price is significantly higher or lower than the previous day's closing price. These jumps are usually triggered by significant overnight news, like an earnings report, a new product announcement, or a major industry development. This creates a sudden, intense imbalance between buyers and sellers.

To see what this looks like in practice, let's watch a clear explanation of a "gap up."

As you saw, a gap represents a powerful shift in market sentiment. Traders classify gaps to better understand their potential implications. While there are several types, the most important distinction for a trader is whether the gap signals the start of a new move or the end of an old one.

Now that we know what a gap is, let's explore the two primary ways traders try to profit from them.

Strategy 1: The "Gap and Go" (A Momentum Strategy)

The "Gap and Go" is a pure momentum strategy. The core idea is that the strong buying (or selling) pressure that caused the gap will continue after the market opens, pushing the price even further in the same direction.

This strategy is especially effective with stocks that have a low float. As a quick reminder, "float" is the number of shares available for public trading. A low float means a smaller supply of shares. When a low-float stock has good news and high demand, the price can move explosively because there simply aren't enough shares to meet the buying interest. This supply-demand imbalance is a concept straight from economics that you'll see play out daily in the market.

Let's see how a professional trader identifies and executes this strategy.

The "Gap and Go" Playbook:

1. Identify: Before the market opens, use a scanner to find stocks gapping up significantly (e.g., >10-20%) on high pre-market volume. Check for a news catalyst and a relatively low float.
2. Plan: Mark the pre-market high on your chart. This is the key resistance level that needs to break.
3. Execute: When the market opens, if the stock breaks out above the pre-market high with strong volume, it triggers a long entry. The momentum is confirmed.
4. Manage: This is a fast-moving trade. Traders often take profits quickly as the initial momentum surge fades.

Strategy 2: The "Gap Fill" (A Reversal Strategy)

What if the initial momentum of the gap fails? Sometimes, a stock gaps up, but the buying pressure isn't strong enough to sustain the move. Early buyers take profits, and sellers step in, pushing the price back down.

This creates an opportunity for a "Gap Fill" trade. The idea is that the price will reverse and fall all the way back down to "fill" the empty space on the chart, returning to the previous day's closing price.

Let's watch a video that explains this concept in more detail.

The "Gap Fill" Playbook:

1. Identify: A stock gaps up significantly but shows signs of weakness at the open. It fails to break the pre-market high and starts trading downwards.
2. Plan: The target for the trade is the price level where the gap began (the previous day's high or close).
3. Execute: A trader would enter a short position as the stock shows clear downward momentum, with the expectation that it will continue to fall until the gap is filled.
4. Manage: The target is well-defined, providing a clear exit point for the trade.

From Theory to a Practical Framework

You now know the two main approaches to trading gaps. To bring this all together, let's look at a structured guide that outlines the different types of gaps and the strategies associated with them.

For an even more rule-based approach, which can be helpful as you start, some traders use time-based rules. For example, the article "Gap Trading Strategies" from ChartSchool suggests waiting for the first hour of trading to complete (from 9:30 AM to 10:30 AM ET) to see where the stock settles. Then, you could place a buy order above the high of that first hour or a short-sell order below the low of that first hour. This is a more patient method that waits for the initial chaotic open to resolve.

Conclusion

Congratulations on completing the Active Trading Strategies module! Today, you've added a powerful, event-driven setup to your toolkit. Trading gaps requires quick thinking and a solid understanding of momentum, but the logic is rooted in the fundamental principles of supply and demand that you're becoming familiar with.

Key Takeaways:

• Price Gaps are significant price jumps between trading sessions, usually driven by news.
• The "Gap and Go" strategy is a momentum play, betting that a strong stock will continue in the direction of the gap, often triggered by a break of the pre-market high.
• The "Gap Fill" strategy is a reversal play, betting that a weak gap will fail and the price will return to the previous day's close.
• Key factors for successful gap trading include a strong catalyst, high relative volume, and understanding the stock's float.
