Gaps and indicator signals are supplementary tools. They do not replace candlestick patterns or chart structure — they confirm them, or add context to setups that already exist. A Breakaway Gap is meaningful because of where it appears and what volume accompanied it, not because gaps are inherently tradeable. A Bollinger Band squeeze is meaningful because it warns of an imminent move, not because bands touching each other guarantees a specific direction.
This lesson covers the final category in the 58-pattern dataset: gap patterns and indicator-based setups. Nine patterns in total. Some of the most cited patterns in trading literature appear here with win rates that should give you pause. The goal is not to dismiss gaps and indicators — it is to use them accurately.
Understanding Gaps
A gap occurs when price opens significantly above or below the previous session's close, leaving a visible empty space on the chart where no trading happened. Gaps are caused by news events, earnings releases, economic data prints, or overnight positioning that shifts supply and demand before the market opens.
On daily charts, gaps appear between Friday's close and Monday's open, or on any day where after-hours news moves price substantially. On intraday charts, gaps appear at the open of each session — the 9:30 AM open in US equities is the most common intraday gap point.
Not all gaps are equal. The trading literature categorises them into types, and the win rates in this dataset show that those distinctions matter enormously. The same visual pattern — an empty space on the chart — can signal the beginning of a powerful new trend, a temporary pause in an existing trend, or nothing tradeable at all. The six gap types ranked by win rate tell you which is which.
The 6 Gap Types Ranked by Win Rate
1. Continuation Gap — Mid-Trend Acceleration (#56)
The Continuation Gap, sometimes called a Runaway Gap, appears in the middle of an established trend. Price has already been moving in one direction with momentum, and then gaps further in the same direction — accelerating the move rather than starting or ending it.
The interpretation is straightforward: this gap signals that the existing trend has more energy behind it. Institutional participants are committing to the move. The gap itself is the evidence that demand (in an uptrend) or supply (in a downtrend) was strong enough to push price past a full session's worth of trading without touching it.
Win rate on Daily: 68%. The best gap pattern in the dataset.
Entry approach: enter in the trend direction after the gap session confirms no immediate fill. Stop below the gap on bullish setups, above the gap on bearish setups.
2. Breakaway Gap Continuation (#52)
The Breakaway Gap appears at the start of a new trend, not the middle. It breaks out of a consolidation range or a prior trend structure — often jumping above a key resistance or below a key support — on noticeably higher volume than recent sessions.
High volume is the critical qualifier. A Breakaway Gap on average volume is a much weaker signal. The volume confirms that institutional money is participating in the move, not just retail imbalance at the open. Without volume confirmation, classify the gap as Common or Exhaustion until proven otherwise.
Win rate on Daily: 65%. The second-best gap pattern.
3. Island Reversal (#54)
The Island Reversal is the rarest pattern in the gap category and one of the rarest in the entire 58-pattern dataset. It forms when price gaps away from a trend, trades in an isolated range for one or more sessions, and then gaps back in the opposite direction — leaving the isolated candles as a literal island on the chart with gaps on both sides.
The rarity is its strength. When an Island Reversal forms and is confirmed by the return gap, it signals that both the breakaway move and the recovery move had sufficient institutional force to create gaps. Two institutional-grade moves in opposite directions around the same price cluster is a powerful reversal signal.
The 5-minute timeframe produces no reliable data for Island Reversal — the pattern simply does not have time to form on sub-15-minute charts with any structural meaning.
Win rate on Daily: 65%. Tied with Breakaway Gap. Valid only when confirmed — both gaps must be present.
4. Exhaustion Gap (#55)
The Exhaustion Gap appears at the end of an extended trend. After a sustained directional move, price gaps further in the trend direction — but this gap is not a continuation signal. It is the final burst of energy before the trend reverses. Sellers (in an uptrend) who were waiting for one more push higher finally get it and begin positioning against the trend.
The challenge with Exhaustion Gaps is identification in real time. When the gap forms, it looks identical to a Continuation Gap. The difference only becomes clear retroactively when the trend does not continue. The practical workaround: treat any gap that occurs late in a mature trend — after a long sustained move without significant pullbacks — with caution rather than as a continuation signal.
Win rate on Daily: 60%. Usable but requires trend context.
5. Gap Fill Assumption (#51)
The Gap Fill Assumption is not a specific gap type — it is a trading strategy based on the belief that all gaps eventually fill. Traders who follow this approach enter counter-gap positions after any gap, expecting price to return to the gap origin.
The data is clear: this assumption is partially true but inconsistently reliable enough to base a strategy on. Daily win rate of 55% means this works slightly more often than it fails — but 55% is not a tradeable edge without additional confirmation. Some gaps fill within the same session. Some gaps do not fill for months. Some never fill. The strategy works best on Common Gaps and fails badly on Breakaway Gaps, where the gap origin represents a broken level that price may not revisit for a long time.
Win rate on Daily: 55%. Treat as context, not a primary entry strategy.
6. Common Gap (#53)
The Common Gap is a small gap that forms without meaningful context — no breakout of structure, no trend acceleration, no exhaustion signal. It appears on ex-dividend dates, at minor news events, or simply from overnight order flow imbalance. There is no structural reason for the gap to be significant.
| Breakaway Gap (#52) — Trade This | Common Gap (#53) — Skip This | |
|---|---|---|
| Volume | Significantly above average — institutional participation confirmed | Average or below — no institutional signal |
| Location | Breaks out of prior consolidation or reverses prior trend structure | Mid-range, no structural significance |
| Daily win rate | 65% | 50% |
| Entry | In gap direction after confirmation session | No reliable entry exists — pattern is noise |
| Context | Start of new trend; typically follows a period of range compression | Ex-dividend, minor news, overnight imbalance with no follow-through |
Bollinger Band Squeeze — Volatility Compression Signal (#28)
Bollinger Bands are two standard deviation bands plotted above and below a moving average. When price volatility decreases, the bands converge toward the moving average — a condition called the squeeze. When a squeeze resolves, price typically moves sharply in one direction as volatility expands back to normal levels.
The Bollinger Band Squeeze signal is that compression is happening and a large move is coming. That statement is accurate. What the squeeze does not tell you is which direction the move will go.
This is the single most important fact about Bollinger Band Squeeze trading: the squeeze predicts magnitude, not direction. Traders who enter positions during a squeeze because "the move is coming" are taking a directional position without directional evidence. That is not a strategy — it is a guess with a technical label.
The correct approach has two phases. First, identify the squeeze — bands within a notably narrow range relative to the last 20–30 sessions. Second, wait. Do not enter until the bands begin to expand and price breaks out of the squeeze range in a specific direction. The entry is the band expansion direction, not the squeeze formation itself.
Win rates of 60–65% on 1-hour and 4-hour timeframes reflect the moderate precision of timing a squeeze break. The squeeze is identifiable. The breakout direction, once it occurs, is also identifiable. The imprecision comes from timing the exact moment the squeeze resolves — you can be positioned slightly early or slightly late, affecting entry price and stop distance.
The Daily timeframe produces low win rates for Bollinger Band Squeeze because daily squeezes can persist for weeks or months before resolving. The holding period becomes impractical and the stop-to-target ratio deteriorates.
Moving Average Bounce — Dynamic Support and Resistance (#57)
When price deviates significantly from its moving average and then returns to it, the moving average acts as a dynamic support or resistance level. The Moving Average Bounce is a reversion-to-mean trade: enter when price touches a major moving average after an extended deviation, expecting the average to hold and price to continue in the primary trend direction.
The moving averages that matter for this pattern are the major ones: the 50-period, 100-period, and 200-period MAs. These are the levels where institutional participants pay attention. A bounce off the 200-day MA is a meaningful event because hundreds of market participants are watching that level simultaneously. A bounce off a 13-period MA carries no comparable institutional weight.
Timeframe significantly impacts reliability. On 5-minute charts, a 200-period MA is 200 five-minute bars — roughly 16 hours of data. That is not a level any institutional trader monitors. On the 4-hour and daily charts, the same periods represent months of price history — levels that appear on professional charts everywhere.
Win rate of 48% on 5-minute charts reflects this. The pattern is statistically unreliable at sub-hourly timeframes. Win rate climbs to 60–65% on 4-hour and daily charts where the MAs carry genuine institutional significance.
Practical application: use MA Bounce as a confirmation tool for candlestick setups. When a Hammer or Bullish Engulfing forms exactly at the 200-period MA on a daily chart, the MA adds weight to the candlestick signal. The MA alone is not sufficient — price touches moving averages and continues through them regularly. The candlestick pattern AT the MA is the entry signal. The MA is the context.
Bollinger Band Extreme — Overbought and Oversold (#58)
When price touches or closes beyond the outer Bollinger Band, it is technically overbought (upper band) or oversold (lower band) relative to the 2-standard-deviation range. Many traders treat this condition as a reversal signal — the assumption being that price has moved too far and must snap back.
The data does not support this as a standalone entry.
A 38% win rate on 5-minute charts means price touching the outer band is more likely to continue than to reverse on short timeframes. Strong trends frequently ride the outer Bollinger Band for extended periods — every candle closing at or beyond the band, none of them reverting. In trending markets, the outer band becomes a trend continuation signal, not a reversal signal.
The pattern becomes marginally useful only when combined with a candlestick rejection signal at the band. A Hammer forming exactly at the lower Bollinger Band on a 4-hour chart, after an extended move down, is a legitimate setup. The band confirms that price has moved significantly from its mean. The Hammer confirms that sellers pushed lower and buyers rejected the extension. Together they are meaningful. The band alone is not.
Chart — Breakaway Gap Opening Above Resistance
Breakaway Gap — Opening Above Resistance on High Volume
The chart shows five sessions of consolidation between 174.50 and 181.50, with resistance holding at the top of that range. On January 15, price opens at 186.00 — a gap of 4.50 points above the prior close of 180.00, clearing the 181.50 resistance entirely and opening above it with no trading occurring in the gap zone. This is a Breakaway Gap. Entry on the following session at 190.50 open, after the gap session confirms no immediate fill. Stop below the gap fill level at 185.50. The trend continues for four additional sessions reaching 199.00.
Using All Three Indicator Patterns Together
The practical framework for integrating these patterns:
- Bollinger Band Squeeze: monitor for compression on 1-hour or 4-hour charts; do not enter until breakout direction confirms; use a breakout candlestick (strong bodied candle closing decisively outside the squeeze range) as the entry trigger
- Moving Average Bounce: identify the major MA level (50, 100, or 200) on 4-hour or daily; wait for price to touch it after a sustained deviation; require a candlestick reversal pattern at the touch before entering
- Bollinger Band Extreme: identify price at the outer band on 4-hour or daily; require a candlestick rejection pattern (Hammer, Shooting Star, Bearish Engulfing, Bullish Engulfing) at the band level; enter only on the candlestick signal, not the band touch alone
The gap patterns follow a simpler rule: classify the gap correctly, then trade only Breakaway and Continuation gaps with volume confirmation. Avoid Common Gaps. Treat Exhaustion Gaps as a warning against continuation trades rather than as a standalone reversal entry.
How do I tell a Breakaway Gap from an Exhaustion Gap in real time?
In real time, you often cannot. Both look like a strong gap in the direction of recent momentum. The distinction becomes clearer retrospectively when you see whether price continues after the gap or stalls and reverses. The practical approach is to use context rather than gap appearance alone. A gap that occurs early in a trend — breaking out of a defined consolidation range with high volume — is more likely a Breakaway Gap. A gap that occurs after a sustained directional move of many sessions, with no significant pullback, and arrives at a known resistance or support level, is more likely an Exhaustion Gap. Volume also helps: Breakaway Gaps typically show volume 1.5–2x the recent average or more. Exhaustion Gaps often show elevated volume too, but the key tell is that price fails to sustain above (or below) the gap open in the sessions that follow. When uncertain, size the position conservatively and let the first follow-through session confirm.
Should I trade gap fills when a gap occurs?
The Gap Fill Assumption strategy (pattern #51, 55% Daily win rate) is not recommended as a primary approach. The 55% win rate is marginally above 50% — not a genuine statistical edge. The more useful framing is to use unfilled gaps as support and resistance levels. A Breakaway Gap that opens above prior resistance often turns the gap zone into a new support level — price may return to test it later, and a candlestick reversal pattern at the gap support is a legitimate entry. The gap zone matters as a level. A counter-gap trade immediately after the gap forms, based purely on the assumption it will fill, is a low-quality setup.
