Gap and Go Strategy
A gap is the jump between yesterday's closing price and today's opening price. When a stock opens far from where it closed and then pushes further in the same direction, the gap and go strategy trades the continuation.
What is gap and go?
Stocks gap when something changes overnight: an earnings report, an upgrade, a piece of news, or a move in the wider market. A large gap means many people want in or out at once, and that pressure does not always clear in the first few minutes.
The strategy lets the first 15 minutes pass. That opening burst sets a small range. If price then closes beyond that range in the same direction as the gap, it shows the move is being extended and not reversed, and the strategy enters with it.
Not every gap continues. Many open at their best price of the day and drift back as early buyers take profits, which is the opposite trade, known as a gap fade. The difference usually comes down to whether there is a real reason behind the gap and real volume supporting it.
The rules StreetAlpha uses
Many versions of this strategy exist. These are the exact rules the AI Day Trader applies, on 5-minute bars, to SPY, QQQ, IWM and two stocks chosen each morning.
| The gap | The opening price is at least half of the ticker's average daily range away from the prior day's close. |
|---|---|
| The early range | The high and low of the first 15 minutes of regular trading, 9:30 to 9:45 AM Eastern. |
| The trigger | A 5-minute bar closes beyond that range in the direction of the gap, when the bar before it closed inside. A gap up can only produce a long, and a gap down only a short. |
| When | Between 9:45 and 10:30 AM Eastern. |
| Target | One width of the early range beyond the entry. |
| Invalidation | The middle of the early range. |
| Time limit | 60 minutes. |
| Limits | One per ticker per day. Nothing is taken in the minutes around a major scheduled economic release. |
A worked example
Say a stock closed yesterday at 80.00 and normally moves about 2.00 in a day. This morning it opens at 81.40 after strong earnings. The gap is 1.40, well over half its normal daily range.
In the first 15 minutes it trades between 81.10 and 81.90. That early range is 0.80 wide, with its middle at 81.50.
At 9:55 a bar closes at 82.05, above the early range. That is a long setup at 82.05. The target is one range width higher, at 82.85, and the invalidation is the middle of the range, at 81.50. The call has until 10:55.
The numbers in this example are made up to show the mechanics. They are not a real trade.
Live results
Every gap and go setup the rules find is recorded when it happens and followed to its outcome, whether or not the AI takes it. Nothing is added or removed afterwards.
This is a young record. Tracking began on October 5, 2026. With 0 graded setups so far, these figures can swing a long way on a single trade and say little yet about how the strategy performs.

Tracked since October 5, 2026, through October 5, 2026. Results are the percent move from entry to exit, with every call the same size, added up, after an assumed cost of 0.02% per trade. "Every setup taken" counts each setup the rules found whether or not the AI took it. Results are hypothetical and no trades are placed.
When it tends to work, and when it does not
Tends to work when
- There is a clear reason for the gap, such as earnings or significant news.
- Volume is far above normal, and it holds up as price breaks the early range.
- The wider market is moving the same way, or at least not against it.
Tends to fail when
- There is no visible reason for the gap.
- The stock opens at its high and sells off from the first minute.
- The gap comes from a market-wide move after an economic release, in a market with no trend. Those are often retraced.
How the AI decides whether to take one
When the rules find a gap and go, the AI is told it is a bet that a large opening gap keeps going. The first thing it looks for is why the gap happened.
What counts in its favor
- A clear catalyst behind the gap
- Heavy volume
- Options flow agreeing with the direction
- A daily trend that points the same way
What counts against it
- No visible reason for the gap
- Volume fading as price breaks the early range
- The index ETFs moving the other way
- A break that only just clears the range
Each decision is published with its reasoning. When the AI passes, the page later shows what taking the setup would have returned, so its judgement can be checked.
Common mistakes
Buying at the opening bell. The first minutes after a gap are the most erratic of the day. Waiting for the early range to form and break gives a defined entry and a defined exit.
Ignoring the reason. A gap on real news behaves differently from one with no cause. The second kind fades far more often.
Chasing an extended move. If price has already run a long way past the range, most of the target is used up while the invalidation is no closer.
Treating every gap alike. Small gaps and gaps in the index ETFs are much more likely to fill than large gaps in individual stocks with news.
Questions
What is the gap and go strategy?
It is a day trading approach that looks for stocks opening well above or below the prior close and trades in the direction of the gap once price shows it is continuing, usually by breaking an early range.
What is a gap in stock trading?
A gap is the difference between one session's closing price and the next session's opening price. It appears as an empty space on a price chart.
What is the difference between gap and go and gap fade?
Gap and go trades in the direction of the gap, expecting it to extend. A gap fade trades against it, expecting price to move back toward the prior close. Which one is right depends largely on what caused the gap.
How big does a gap need to be?
There is no fixed rule. StreetAlpha requires the gap to be at least half of the ticker's average daily range, so that it is large relative to how that particular stock normally moves.
