Gap Trading Strategy: Continuation Gaps Explained
Updated: 2 days ago
A gap trading strategy studies the empty price area between one session and the next. The gap itself is not a signal: its location, the trend, liquidity, confirmation and predefined risk determine whether a setup is tradable.

Key Takeaways
A continuation gap occurs within an established trend, while a breakaway gap leaves a base or trading range.
Volume can strengthen the evidence, but no single volume threshold guarantees continuation.
Wait for price behaviour to confirm the setup rather than buying solely because a gap appeared.
Calculate position size from the planned loss and stop distance, not from confidence in the pattern.
Overnight repricing can jump through a stop, so the realised loss may exceed the planned loss.
What Is a Price Gap?
A price gap appears when a security opens above or below the prior session’s trading range, leaving an area on the chart where no transactions occurred. Earnings, guidance, corporate news, macroeconomic events and changes in supply or demand can all cause rapid repricing.
Not every gap is meaningful. A small gap inside a noisy range has a different context from a decisive gap above multi-week resistance. Classification is therefore a starting point for analysis, not a prediction.
The Four Main Types of Gap
Common Gap
A common gap forms inside an existing trading range. It may close quickly because the market has not escaped the surrounding support and resistance. Treat “gaps always fill” as a market saying, not a dependable rule.
Breakaway Gap
A breakaway gap moves price beyond a defined base, range or resistance level. The breakout location is the distinguishing feature. A strong close and increased participation can add evidence, but false breakouts remain possible.
Continuation or Runaway Gap
A continuation gap appears after a trend is already established and may reflect a new wave of buyers or sellers accepting substantially different prices. The setup is stronger when the wider trend, relative strength and market backdrop agree.
Exhaustion Gap
An exhaustion gap appears late in an extended move and is followed by failure or reversal. It can initially resemble continuation, which is why the closing range, follow-through and reaction over subsequent sessions matter.
How to Assess a Continuation Gap
Start with context. The following conditions create a more testable continuation thesis, but none should be treated as a guarantee:
A clearly established trend before the gap rather than an isolated jump from a directionless range.
A catalyst or visible change in demand that plausibly explains the repricing.
Adequate liquidity, a reasonable spread and enough turnover for the intended position size.
A close that holds much of the gap instead of immediately reversing into the prior range.
Follow-through, consolidation above the gap or an orderly retest that respects support.
A broad-market and sector backdrop that does not strongly contradict the trade direction.
Volume is supporting evidence rather than a verdict. A large increase may show broader participation, but the appropriate comparison depends on the security, session and catalyst. Average True Range (ATR) can also help place the gap in the security’s recent volatility context.
Entry, Stop and Position-Size Plan
Write the trade plan before entering. A simple process is:
Define the exact trigger: immediate strength, a close above the gap-day high, or a controlled pullback.
Mark the technical invalidation point, such as a failure below the gap-day low or back into the prior range.
Calculate risk per share from entry minus stop for a long trade, or stop minus entry for a short trade.
Divide the maximum account risk by risk per share to estimate the maximum position size.
Reduce size or reject the trade if spread, slippage or overnight gap risk makes the planned loss unrealistic.
For example, a £10,000 account risking 0.5% has a £50 maximum planned loss. If the entry is £20 and the stop is £19.50, risk is £0.50 per share, so the theoretical maximum is 100 shares before costs and slippage. See the risk-management and position-sizing guide for the full framework.
Gap Risk and Stop-Order Limitations
A stop is an instruction, not a guaranteed exit price. If price gaps through the stop, a market stop may fill at the next available price. A stop-limit order controls the acceptable price but may not execute at all.
The SEC’s Investor.gov stop-order bulletin explains that execution can deviate significantly from the stop price when liquidity is limited. This is especially relevant to gap trading, where overnight news is part of the setup and also part of the risk.
Use the stop-loss guide alongside the risk-to-reward guide to evaluate both planned and realised risk.
A Corrected Historical Example
The original Financial Wisdom example described a Goldman Sachs trade with a stated entry at $131, a stop at $129.80 and an exit at $150.72. Those figures imply:
Initial risk per share: $131.00 - $129.80 = $1.20.
Realised gain per share: $150.72 - $131.00 = $19.72.
Price return before costs: approximately 15.1%.
Ex-post gain relative to initial risk: approximately 16.4R, not a pre-trade guarantee.
This is a historical illustration based on the prices stated in the original material. It does not show every fill, cost or decision required to reproduce the result. The former annualised extrapolation has been removed because repeating one short holding-period return across a year would create an unrealistic impression.
A second historical Carnival example remains available in the video, but the old transcript did not provide enough complete trade data to verify its claimed risk multiple. It should be treated as an educational chart example, not audited performance.
Common Gap-Trading Mistakes
Assuming every gap must fill or every high-volume gap must continue.
Buying an extended opening move without defining where the thesis fails.
Using a fixed percentage stop that ignores the security’s volatility and chart structure.
Calculating position size from buying power rather than maximum acceptable loss.
Ignoring spreads, slippage, earnings dates and the possibility of another overnight gap.
Annualising one successful short-term trade or presenting an isolated example as an expected return.
Pre-Trade Gap Checklist
Which gap type best fits the chart context?
What event or change in supply and demand may have caused the repricing?
Has price held the gap, closed strongly or confirmed with follow-through?
Where is the technical invalidation level?
What is the maximum account loss and resulting position size?
Could a gap through the stop make the actual loss materially larger?
Is the proposed reward attractive after realistic costs and execution assumptions?
Frequently Asked Questions
Do all price gaps eventually fill?
No. Some common gaps close quickly, while breakaway and continuation gaps can remain open for long periods. The surrounding trend and range structure matter more than the saying.
What is the difference between a breakaway and continuation gap?
A breakaway gap exits a base or trading range. A continuation gap occurs after the trend is already established and may mark renewed participation within that move.
Is high volume required?
Higher-than-usual volume can support the thesis, but there is no universal threshold and a volume spike does not guarantee follow-through. Compare volume with the security’s normal activity and the catalyst.
Where should a stop be placed?
Use a chart level that invalidates the setup, then calculate whether the resulting position size and potential gap-through risk fit the account. A convenient fixed percentage is not automatically appropriate.
Can gap trading be backtested?
Yes, if the rules define the gap size, prior trend, entry timing, liquidity, costs and exit logic without look-ahead bias. Use out-of-sample and forward testing before risking meaningful capital.
