Opening gaps are emotionally powerful because the market has already moved before most traders place their first order. A gap up feels like missed opportunity. A gap down feels like panic. Both feelings are dangerous. The professional approach is to classify the gap, wait for confirmation, and decide whether the gap is likely to continue, fade, or trap late participants.
For Indian equity and index traders, gaps usually come from overnight global cues, company results, regulatory announcements, commodity moves, currency moves, or large pre-open order imbalances. The gap itself is only the first clue. The trade comes from how price behaves after the open.
| Gap Type | Typical Context | Preferred Response |
|---|---|---|
| Breakaway gap | Price opens beyond a multi-day range with strong volume | Look for continuation after a shallow pullback |
| Continuation gap | Trend is already established and gap aligns with trend | Trade with trend only if the first pullback holds |
| Exhaustion gap | Late-stage trend, news excitement, very wide opening range | Avoid chasing; watch for failed high or failed low |
| Common gap | Small gap inside prior range without news or volume | Usually ignore unless it creates a clean intraday level |
The first 30 minutes reveal whether the gap has real sponsorship. A bullish gap that holds above VWAP, builds higher lows, and sees expanding volume on upticks is different from a gap that immediately sells below the opening print. A bearish gap that cannot reclaim the first 15 minute high is different from a bearish gap that quickly fills 50 percent of the gap.
A useful process is to mark three levels before taking any trade: previous close, opening price, and the high/low of the first 15 to 30 minute range. These levels define the decision zone. If price stays above the opening range after a gap up, continuation is alive. If it breaks below the opening range and VWAP, the gap may become a fade setup.
Worked example: Nifty previous close is 22,400 and the market opens at 22,624. The opening gap is ((22,624 - 22,400) / 22,400) x 100 = 1.00%. If the first 30 minute range is 22,590 to 22,710 and the entry is 22,705, the opening range risk is ((22,710 - 22,590) / 22,705) x 100 = 0.53%. A trader whose normal intraday stop tolerance is 0.25% should either reduce size or skip the chase.

The mistake is buying the opening candle simply because the gap is large. Good gaps allow structured risk. Bad gaps force wide stops and emotional decisions.
A gap fade is a counter-move trade, so confirmation matters even more. The best gap fades happen when the market opens far from the prior close, fails to attract follow-through, then breaks back inside the opening range. For a gap up, a fade trigger often appears when price loses VWAP and cannot reclaim it. For a gap down, a fade trigger often appears when price reclaims the opening range high and holds above VWAP.
Gap fades work best when the gap is caused by broad emotion rather than stock-specific fundamental change. If a company has a genuine earnings shock or governance event, fading the gap can be dangerous because sellers or buyers may continue for several sessions.
