Identifying and Trading Common Gaps
Common gaps occur within a trading range without a significant trend shift. These gaps typically appear in stocks like AAPL or SPY during normal market hours when the price opens sharply higher or lower but fills the gap within a few hours or days. For example, AAPL might close at $150.00 and open the next day at $151.50, creating a $1.50 gap. This gap often fills quickly as sellers or buyers close positions.
Common gaps represent a temporary imbalance between supply and demand. They reflect short-term order imbalances, not major fundamental changes. In the S&P 500 E-mini futures (ES), a common gap might be a 2-3 point difference between yesterday’s close and today’s open, followed by a reversal to fill that gap within the first 30 minutes of trading.
Traders use common gaps for quick scalps or fade trades. When AAPL gaps up $1.50 but volume at open is low, fading the gap with a tight stop above the high offers a 1:2 risk-to-reward (R:R) setup. For instance, enter short at $151.25, stop at $152.00 (+$0.75 risk), target $150.00 (-$1.25 reward). This trade yields 1.67 R:R.
Common gaps fail when strong momentum supports continuation. For example, TSLA gapped up $10 at open on a news catalyst but buyers overwhelmed sellers, pushing price higher without filling the gap. Traders fading this gap faced a stop-out as price surged to $700 from a $690 open. Volume above 1 million shares in the first 15 minutes confirms momentum, signaling not to fade.
In futures like crude oil (CL), common gaps form during overnight trading hours due to low liquidity and news. These gaps often fill during the regular session. A $0.50 gap in CL from $70.00 to $70.50 typically retraces by $0.40 within three hours. Traders fade these gaps with stops 0.10 above the high, targeting a fill at $70.05-$70.10.
Breakaway Gaps Signal New Trends or Breakouts
Breakaway gaps occur when price breaks out of a consolidation or trading range with volume spikes. These gaps show strong conviction and mark the start of a new trend. For example, NQ futures breaking above a resistance level at 13,800 with a 30-point gap and 50,000 contracts traded signals a breakaway gap.
Breakaway gaps appear on high volume, often 50% or more above the 20-day average volume. SPY might gap from $400 to $405 on 100 million shares when breaking above a key level, confirming a breakaway gap.
Traders enter long on breakaway gaps after the first pullback tests the gap area. For example, ES gaps from 4,200 to 4,215 with 80,000 contracts and retraces to 4,210. Enter long at 4,210, stop below 4,200, target 4,240. Risk is 10 points, reward is 30 points, yielding 1:3 R:R.
Breakaway gaps fail if volume is weak or price closes back inside the prior range. For instance, if GC (gold futures) gaps above $1,950 but closes at $1,940 on low volume, the breakout lacks conviction. Traders holding longs risk sharp reversals. Use volume and close confirmation to avoid false breakaways.
Breakaway gaps also fail when news catalysts are false or quickly reversed. TSLA gapping up $15 on earnings but closing near the previous day's close signals a failed breakaway, leading to rapid gap fill and stop hits.
Runaway Gaps Occur Mid-Trend, Confirming Momentum
Runaway gaps appear after a trend establishes, confirming momentum continuation. These gaps occur in trending markets like ES or AAPL during strong rallies or declines. For example, TSLA trading at $600 gaps to $615 mid-rally, confirming buyer strength.
Volume on runaway gaps typically matches or slightly exceeds the average daily volume, unlike breakaway gaps which spike volume. Runaway gaps show price strength but lack the volume surge of breakaways. For example, NQ at 14,000 gaps 20 points to 14,020 with volume near the 20-day average of 40,000 contracts.
Traders add to positions on runaway gaps with tight stops below the gap. Enter long TSLA at $615, stop at $610, target $630. Risk is $5, reward $15 for 1:3 R:R.
Runaway gaps fail when momentum stalls or reverses sharply after the gap. For example, AAPL gaps up $3 mid-trend but reverses to fill the gap within two days due to profit-taking or unexpected news. Traders should monitor volume and price action closely.
Runaway gaps often fail near resistance or exhaustion zones. GC might gap up $10 toward $2,000 resistance but retrace 50% of the gap within 24 hours, signaling waning momentum.
Exhaustion Gaps Mark Trend Endings or Reversals
Exhaustion gaps appear near the end of a strong trend and signal potential reversals. They show final bursts of momentum but lack follow-through volume. For example, ES uptrend from 4,000 to 4,150 gaps to 4,160 with low volume compared to prior days.
Volume on exhaustion gaps drops 30-50% versus the previous gap or trend days. TSLA might gap from $720 to $730 with volume decreasing from 3 million shares to 1.5 million, indicating exhaustion.
Traders watch for exhaustion gaps to exit positions or enter counter-trend trades. For example, short ES at 4,160 after an exhaustion gap with a stop at 4,170 and target 4,130. Risk is 10 points, reward 30 points, 1:3 R:R.
Exhaustion gaps fail when momentum continues unexpectedly. SPY might gap down $2 near a low but buyers push price higher, negating an exhaustion signal. Confirm with volume and price action before committing.
Exhaustion gaps also fail in volatile markets with news-driven spikes. CL might gap up $1 near highs but continue rising, invalidating the exhaustion gap.
Worked Trade Example: SPY Breakaway Gap Trade
SPY closes at $400.00 on Friday. On Monday, it gaps up to open at $406.00, breaking above resistance at $405. Volume reaches 120 million shares compared to 80 million average.
Price pulls back to $405.50 within 30 minutes. Enter long at $405.50. Place stop at $403.50 below prior resistance turned support. Target $412.00 near next resistance.
Risk: $2.00 per share. Reward: $6.50 per share. R:R ratio: 3.25:1.
Price rallies to $412.00 in two days. Exit trade for a $6.50 gain. Stop remains intact. Trade confirms breakaway gap strength after pullback.
If volume had been weak (below 80 million) or price closed back below $405, the trade would have failed, signaling a false breakout.
Key Takeaways
- Common gaps form within ranges and usually fill quickly; fade them with tight stops and watch volume for momentum signs.
- Breakaway gaps signal new trends on volume spikes; enter on pullbacks, confirm volume and price close.
- Runaway gaps confirm ongoing trends without volume spikes; add to positions but monitor for reversal signs.
- Exhaustion gaps appear near trend endings with declining volume; use for exits or counter-trend entries but confirm with price action.
- Use volume, price confirmation, and key support/resistance to differentiate gap types and improve trade success.
