A gap is context rather than a completed strategy
An opening gap compares today's regular-session opening price with the preceding regular-session close. A stock opening above yesterday's close has a positive gap, but that observation alone does not define an entry, protective reference, or exit. This example requires a later opening-range breakout and VWAP filter before considering a hypothetical next-bar proposal.
The illustrative allowed gap is 2% through 8%, inclusive. Those bounds define the experiment; they are not optimized thresholds or proof that smaller or larger gaps are universally unsuitable. A stock outside the interval simply does not belong to this version. Do not change the bounds after observing which gaps happened to continue that day.
Use the correct opening and prior close
Premarket last trade, opening auction price, and the first five-minute bar's close are different observations. The gap calculation here uses the regular-session open. The prior reference is the preceding regular-session close, adjusted consistently for corporate actions. A split or ex-dividend adjustment can otherwise distort the apparent gap.
The formula is (session open / prior close − 1) × 100. For an open of $48.80 and prior close of $47, the gap is approximately 3.83%. It meets the stated interval. A premarket trade at $50 does not replace the $48.80 regular opening in that formula simply because it makes the chart look more dramatic.
Freeze the opening range before continuation
As in the opening-range example, the first three completed five-minute regular-session bars define the 09:30–09:45 America/New_York range. The range is frozen afterward. The range low must remain above the prior regular-session close. This extra condition distinguishes the example from an opening gap that has already been fully filled during range formation.
A later completed five-minute close must freshly cross above the range high, with the preceding close at or below that line. The close must also exceed regular-session VWAP. Only bars ending after 09:45 and no later than 11:00 qualify. The next-bar proposed entry cannot exceed the range high by more than 0.25 range heights.
News and halt review remain distinct requirements
A gap can follow earnings, a filing, an analyst action, a financing announcement, or a market-wide move. A headline summary without a source and timestamp is incomplete context. The exercise includes an explicit news and halt-status review state rather than pretending to interpret a catalyst from the size of the gap.
A confirmed catalyst does not guarantee a favorable move. Trading halts can prevent planned exits, and spreads can change rapidly around resumptions. The tool does not independently verify news, exchange status, borrowing, or liquidity. Unknown states remain visible and should not be converted into a passing result because the price pattern looks clean.
Work a gap and continuation case
Assume yesterday's regular close is $47 and today's regular open is $48.80. The first-15-minute high is $49.80 and low is $48.80. The gap is about 3.83%, and the range low remains above the old close. The bar ending at 09:50 closes at $50 above a $49.50 VWAP, while the preceding close was $49.60.
For a hypothetical next-bar entry at $50, the extension above the $49.80 range high is $0.20, within the $0.25 allowance from the $1 range. The stop reference is the $48.80 range low, and the fixed two-distance target is $52.40. The modeled net scenario includes the chosen per-share friction and fixed round-trip costs.
Change the prior close to $48.50 while retaining the $48.80 open. The gap becomes about 0.62% and fails the minimum condition even though a breakout may still occur. Change the range low to $46.90 instead: the opening range has breached the prior close and fails the unfilled-gap context. Change entry to $50.10: the late proposal fails the extension limit. Each example isolates a different operational question.
Continuation can fail quickly
A strong opening move can reverse before the next instruction is filled. A later five-minute close below the frozen range high is the closing failure condition, while the protective reference is considered first. The fixed target and 15:55 time exit complete the stated plan. A halted stock cannot be assumed to honor an intraday flattening schedule.
If stop and target are both inside one bar's high/low range, the sequence is unresolved without finer observations or a declared conservative convention. A closing price above the opening high does not prove that the stop was never reached earlier. Keep the path uncertainty separate from the final close.
Distinguish this strategy from opening-range breakout
Both examples use a frozen opening range and later crossing, but their context differs. Gap-and-go adds the defined opening-gap interval, range low above prior close, and news/halt review. The opening-range lesson instead includes its specific opening-volume ratio condition. Combining only the favorable requirements from each after observing the session creates a third, unstated strategy.
The dedicated exercise keeps the distinction visible through the gap percentage, range height, time window, price relationships, and review states. It is a single-proposal worksheet, not a live catalyst scanner or a session backtest. The useful outcome is a clear record of why a hypothetical proposal qualifies, fails, or remains unresolved under the version selected before the market outcome is known.
Versioned rule card
EDU-2026-11-v1. These illustrative settings define one educational experiment. They are not optimized parameters, a verified edge, or personal trade instructions.
Entry condition 1: Gap percentage uses today regular-session open versus preceding regular-session close; illustrative allowed range is 2% through 8%.
Entry condition 2: Freeze the first 15 minutes as in the opening-range lesson.
Entry condition 3: After 09:45 and no later than 11:00, a completed five-minute close freshly crosses above the opening-range high.
Entry condition 4: Current close above session VWAP; opening-range low remains above prior regular-session close.
Entry condition 5: Review the news source, event calendar, spread, and halt status; model next-bar entry no more than 0.25 range heights above range high.
Exit rule 1: Modeled stop at opening-range low.
Exit rule 2: Target equals entry plus two times planned entry-to-stop distance.
Exit rule 3: Protective exit first; otherwise target, then close below opening-range high, then 15:55 time exit.
From a rule match to an executable paper plan
A strategy condition and an executable order are different objects. First record the completed observation that satisfied the condition. Then write the earliest moment at which that observation could have been known. A rule requiring the final daily close cannot normally be evaluated early enough to assume a fill at that same closing price. The next session may open above, below, or through the proposed reference. Intraday examples have the same sequencing issue at the boundary between a completed five-minute bar and the next bar. The hypothetical entry used in the exercise is a separate input for exactly this reason.
Write the order instruction before calculating a result. A market instruction emphasizes execution while allowing price uncertainty. A limit instruction imposes a price boundary while accepting nonexecution or partial execution. A stop reference is an activation condition, not an insurance contract. A stop-limit instruction can activate without filling. If a gap skips the reference, the chart does not prove that the position could have been closed at that reference. A realistic paper record therefore preserves the planned price, actual assumed fill, quantity filled, remaining quantity, and the reason for any cancellation. These distinctions are explained further in the site's Trading Basics lessons.
Quantity, costs, and a worked execution budget
For a hypothetical long position, planned price risk per share is entry minus stop. For a hypothetical short, it is stop minus entry. Both expressions must be strictly positive. Suppose a long entry is $50, a stop reference is $48.50, the total adverse-friction assumption is $0.05 per share across the round trip, and fixed round-trip charges are $2. With a modeled $100 loss budget, the arithmetic quantity is floor((100 − 2) / (1.50 + 0.05)), or 63 shares. This models $99.65 of loss at the assumed exit, rather than proving an actual maximum loss.
A separate cash check matters. If only $2,000 is allocated to the share purchase and charges, floor((2000 − 2) / 50) permits 39 shares in this simplified cash calculation. The smaller quantity governs the long example. With those 39 shares, a hypothetical $53 target and the same friction produce 39 × (3 − 0.05) − 2 = $113.05 of modeled net gain. The modeled stop loss is 39 × 1.55 + 2 = $62.45. Their ratio is approximately 1.81. That ratio describes two assumed outcomes; it says nothing about how likely either outcome is.
The exercise uses whole shares and a single fixed-friction assumption to keep the arithmetic visible. Borrow fees, financing, taxes, changing spreads, partial fills, market impact, and a stop skipped by a gap require additional treatment. In particular, the long cash-cap input is not a margin or buying-power model for a short position. Review aggregate exposure and correlated positions using the site's Risk Management learning path before treating any individual-position calculation as a complete portfolio plan.
Exit priority and ambiguous bars
The listed exits describe distinct reasons for leaving. The protective reference is checked first under the illustrative plan; a target or closing-bar condition is considered afterward. However, a daily or five-minute OHLC bar may contain both the stop and target without revealing which was reached first. Do not choose the favorable sequence simply because it improves a result. Use finer trustworthy observations, flag the sequence as unresolved, or apply a disclosed conservative convention consistently. A closing-bar exit cannot be assumed to have prevented an earlier intrabar stop touch.
If a target is fixed at confirmation, preserve that original value. If a strategy explicitly updates a trailing reference, record the update time and make the new value effective only afterward. A revised stop should never be applied retroactively to the bar that generated it. A time exit also needs an execution assumption: submitting an order at a chosen time does not establish that the observed chart price was the actual available fill. Record the difference instead of silently replacing the plan with hindsight.
Review evidence without manufacturing a track record
Start a paper test by freezing the rule version, instrument universe, session definition, time zone, data source, corporate-action treatment, and cost assumptions. Include every eligible observation, including failed conditions and unfilled orders. A collection of attractive screenshots is not a complete sample. Missing data should remain missing rather than being converted into a passing condition. The examples here illustrate mechanics and arithmetic; none of the chart paths establishes a historical win rate or expected future return.
If testing historical data later, separate development observations from a subsequent evaluation period. Record every parameter combination tried so that an attractive result is not presented as an independent discovery after many hidden trials. Include delisted instruments when the universe requires them, avoid using future information to select past leaders, and check how split and dividend adjustments affect price and volume comparisons. These details can change which bars qualify even when the indicator names remain identical. The Technical Analysis lessons provide related material on indicators, reference windows, and disciplined testing.
Using the dedicated practice exercise
Open the exercise linked to this strategy and first review the fictional defaults. Change one assumption at a time. The tool evaluates the supplied numbers and explicitly entered review states; it does not retrieve an independent chart or verify a person's judgment. “Meets entered example conditions” means only that the entered conditions satisfy this particular rule version. “Unresolved” identifies required information that has not been confirmed. A failed condition remains a failed condition even when the hypothetical target result is attractive.
After reviewing the result, preserve the inputs and write which observation changed the conclusion. Repeat with a near-boundary example, a missing requirement, and an adverse execution assumption. Reset restores the fictional example. The worksheet does not send orders, connect a broker, or save a trading account. A repeatable process includes decisions to wait, reject a setup, or investigate an unknown; it is not a requirement to produce a trade every session. The Trading Psychology lessons explain how to review those decisions independently of profit and loss.
