Common Gaps: Noise in Price Action
Common gaps occur within a trading range or congestion zone without significant news or volume. They represent temporary price imbalances that fill quickly. For example, SPY often gaps 0.2% to 0.5% intraday due to market maker inventory adjustments. On March 15, 2023, SPY opened at $391.20, 0.3% above the prior close of $390.05, then retraced within 15 minutes, filling the gap by trading back to $390.10. Volume on the gap day registered 20 million shares, slightly below the 30-day average of 25 million.
Traders treat common gaps as noise. They avoid taking directional trades on them because the price usually returns to the prior day's range. Common gaps work when the market lacks conviction and volume remains average or below average. They fail when the gap coincides with a breakout or significant news, turning into breakaway gaps.
In ES futures, common gaps typically measure 2 to 5 ticks (0.25 to 0.63 index points). For example, on May 10, 2023, ES opened 3 ticks higher than the previous close but retraced within 10 minutes. Day traders use limit orders near the gap fill to scalp 1 to 3 ticks, risking 1 tick for 2 to 3 ticks reward.
Common gaps appear mostly in the middle of the trading day, especially after low volume overnight sessions. They rarely happen after the 3:00 PM ET close or pre-market due to lower liquidity.
Breakaway Gaps: Start of New Trends
Breakaway gaps signal strong conviction and the start of a new trend. These gaps occur after a consolidation or congestion phase and mark the breakout point. Volume surges 50% or more above the prior 20-day average. For instance, on April 3, 2023, AAPL broke out from a 10-day range between $158 and $161. The stock gapped from $161.20 to $164.50 at the open, a 2% jump. Volume hit 60 million shares, 70% above the 30-day average of 35 million. Price continued higher, closing at $168 three days later.
Breakaway gaps work when volume confirms the move and the gap holds without filling for at least two trading sessions. They fail when the gap fills quickly, signaling a false breakout or a bull trap. For example, TSLA gapped up 3% on June 12, 2023, from $720 to $742 on news but retraced to $715 within three hours, filling the gap and triggering stop losses.
Trade Setup: On June 5, 2023, CL (Crude Oil futures) formed a tight range between $70.50 and $71.00 for five days. On June 6, it gapped from $71.05 to $72.20, a 1.6% jump on 250,000 contracts traded, 60% above average. Enter long at $72.30 after a 5-minute pullback. Place a stop at $71.00, below the prior range low. Set a target at $74.00, near the next resistance level. Risk $1.30 per barrel to gain $1.70. The risk-to-reward ratio is 1:1.3. The trade closes at target three days later.
Breakaway gaps fail during market reversals or when the broader index declines sharply. For example, on May 18, 2023, GC (Gold futures) gapped up 1% from $1,970 to $1,990 but reversed on a weak US dollar and filled the gap by day’s end.
Runaway Gaps: Trend Continuation with Momentum
Runaway gaps occur in the middle of a strong trend and reflect accelerated momentum. Volume increases moderately, by 20% to 40%, but the gap represents traders catching up with the trend rather than a breakout. On April 20, 2023, NQ futures jumped 30 points from 13,800 to 13,830 during a bullish rally. Volume was 150,000 contracts versus the 7-day average of 120,000. The gap did not fill for five sessions.
Traders use runaway gaps to add to positions. Entry occurs on pullbacks near the gap area or on breakouts above the gap high. Stop losses stay below the gap low. Targets align with measured moves based on trend channels or Fibonacci extensions.
Runaway gaps work in strong trending environments with consistent higher highs and lows. They fail when markets become overextended, leading to exhaustion gaps. For example, on July 10, 2023, ES rallied continuously but a runaway gap at 4,300 broke at the peak. The market reversed sharply the next day, filling the gap and signaling exhaustion.
Example trade: On April 21, 2023, AAPL trades in a confirmed uptrend from $160 to $170 over two weeks. It gaps from $167 to $169.50 on volume 20% higher than the 10-day average. Enter long at $169.75 on a 5-minute pullback. Place stop at $167, below the gap low. Set target at $174 based on prior swing high. Risk $2.75 to make $4.25. Risk-to-reward ratio is 1:1.5.
Runaway gaps often appear after earnings or upgrades during trending phases. Failure occurs if the gap forms near trend exhaustion or after parabolic moves.
Exhaustion Gaps: Warning Signs of Reversal
Exhaustion gaps occur near the end of a trend and signal potential reversal. They feature a large gap accompanied by extremely high volume and volatility but little follow-through. Price gaps up or down dramatically but then retraces quickly, filling the gap within one to two days.
For example, on June 28, 2023, TSLA gapped up from $740 to $780, a 5.4% jump on triple average volume of 50 million shares. The stock reversed intraday and closed at $750, filling most of the gap. Two days later, TSLA fell to $700, confirming the reversal.
Exhaustion gaps work as reliable reversal signals when volume spikes 100% or more above average and price fails to sustain the gap level. They fail when followed by continuation gaps or strong trend resumption.
Trade Setup: On July 5, 2023, ES rallies from 4,200 to 4,350 in ten sessions. It gaps up 30 points to 4,380 on volume doubling the 10-day average. Enter short at 4,375 after a 5-minute pause. Place stop at 4,390, above the gap high. Set target at 4,330, the prior support area. Risk 15 points to gain 45 points. Risk-to-reward ratio is 1:3. The trade closes at target three days later.
Exhaustion gaps often coincide with news or sentiment extremes, such as Fed announcements or geopolitical events. They provide excellent short-term reversal opportunities but require tight stops due to volatility.
Key Takeaways
- Common gaps fill quickly and represent low conviction moves; avoid directional trades without volume confirmation.
- Breakaway gaps mark trend starts with volume surges; trade them with stops below the prior range.
- Runaway gaps indicate trend continuation; add to positions on pullbacks with defined stops.
- Exhaustion gaps signal trend reversal with high volume and quick fill; use tight stops and target prior support/resistance.
- Always confirm gap types with volume and price action before entering trades to improve risk management and reward ratios.
