Understanding Gaps in Bank Nifty
A “gap” occurs when Bank Nifty opens at a price different from the previous day’s close.
Gap Up → Opening higher than previous close, indicating bullish sentiment
Gap Down → Opening lower than previous close, indicating bearish sentiment
Gaps in Bank Nifty often occur due to:
Overnight global market movements, especially in US and Asian banking indices
Sector-specific banking news or RBI policy announcements
Large institutional or FII activity
Sudden market sentiment shifts
Recognizing gaps in Bank Nifty helps traders plan entry, exit, and risk for futures and options positions.
Types of Gaps
Understanding the type of gap is critical for strategy:
Common Gap – Small gap in a range-bound session, often filled quickly
Breakaway Gap – Appears after consolidation, signaling a strong trend
Runaway Gap – Appears mid-trend, confirms continuation
Exhaustion Gap – Appears near trend tops or bottoms, often signaling reversal
Each type guides whether to trade with momentum or fade the gap.
Gap Up Strategy in Bank Nifty
When Bank Nifty gaps up, traders have multiple strategies:
1. Momentum Strategy
Buy Bank Nifty futures or call options if opening above previous high
Confirm with strong volume and positive global banking cues
Target intraday resistance levels or next swing highs
Place stop-loss below previous session’s high
2. Gap Fill Strategy
Wait for retracement toward previous close
Enter long if the gap acts as support
Works best for smaller gaps in neutral conditions
3. Reversal Strategy
Consider shorting futures or buying puts if the gap stalls or reverses early
Use resistance near the gap high as entry point
Stop-loss slightly above the gap high
Gap Down Strategy in Bank Nifty
When Bank Nifty gaps down, strategies are applied in reverse:
1. Momentum Strategy
Short Bank Nifty futures or buy put options if opening below previous low
Confirm with strong selling volume
Target intraday support levels
Stop-loss above previous session’s low
2. Gap Fill Strategy
Observe retracement toward previous close
Enter short if resistance holds at previous close
Profitable if gap partially fills without reversing
3. Reversal Strategy
Buy futures or calls if the price rebounds strongly from gap low
Stop-loss slightly below gap low
Works well near oversold conditions or strong support
Measuring the Gap
Points: Opening – Previous close
Percentage: (Gap ÷ Previous close) × 100
Larger gaps indicate higher volatility and bigger trading opportunities
Very small gaps may represent normal market fluctuations and are less reliable
Role of Volume
Volume confirms the strength or weakness of a gap:
High volume → Gap likely to continue; momentum trades favored
Low volume → Gap may reverse; fading or waiting is safer
Combine volume with intraday charts and global cues for better timing
Support and Resistance
Support and resistance levels improve gap trading accuracy:
Gap up holding above prior resistance → continuation likely
Gap down near prior support → reversal possible
Intraday charts help identify micro support/resistance for precise entries and exits
Options Strike Selection for Gap Trading
Choosing the right strike is critical:
ATM options → Balanced risk and reward, highly liquid
ITM options → Safer, higher probability, but more expensive
OTM options → Lower cost, high potential reward, lower probability
Strike selection should align with gap type, expected move, and expiry:
Short-term gaps → Weekly options, smaller targets
Longer-term trend → Monthly options, larger targets
Intraday vs Positional Gap Trading
Intraday
Focus on first 30–60 minutes
Use ATM options or futures for liquidity
Quick exits and small targets
Position size adjusted for volatility
Positional
Hold trades for multiple sessions if trend is strong
ITM options or futures for safer exposure
Wider stop-loss allowed
Targets can include full gap plus trend continuation
Risk Management
Set stop-loss based on gap size and support/resistance
Avoid over-leveraging
Consider partial profit-taking if momentum slows
Exercise caution during RBI announcements or high-impact news
Common Mistakes
Entering trades immediately at open without confirmation
Ignoring volume trends
Trading insignificant gaps
Over-leveraging positions
Holding losing trades hoping the gap will recover
Ignoring overall market trend
Using the same strategy for all gaps
Advanced Techniques
Gap Fade

Combining Technical Indicators
Moving averages for trend confirmation
RSI for overbought/oversold conditions
MACD for momentum confirmation
