Practical Uses of the Gamma Blast Strategy in Options Trading

The Gamma Blast Strategy is a dynamic options trading approach in which explosive shifts in prices, especially near expiry, are pursued by taking advantage of gamma, which accelerates the underlying change of delta in both ATM and OTM options. The method is popular with aggressive buyers searching for a way to convert meagre premiums into fast, high-multiplier returns during market surges. 

 

Understanding Gamma Blast Strategy

The Gamma Blast strategy in options trading ,targets high gamma options, typically near expiry, where the delta (sensitivity of option price to asset price) changes rapidly with the underlying asset price movement. This creates sharp increases in option premiums on breakouts, favouring buyers as sellers become cautious. 

For example, 

On expiry day after 1:45 PM, if a stock or index, such as Nifty, breaks out on high volume and implied volatility (IV) spikes, buying at-the-money (ATM) or slightly out-of-the-money (OTM) options with high gamma can lead to premiums multiplying 2-3 times within minutes.

A real-time example: 

Suppose Nifty is trading near 18,200 with expiry today. Around 2:00 PM, a sudden breakout on volume with an IV spike occurs at the 18,200 ATM call strike, which has a gamma of 0.08 (high). Buying this call option could cause its premium to rapidly increase 2-3 times as delta accelerates with the underlying price surge.

 

Traders scalp these gamma bursts by entering post 1:45 PM to benefit from this accelerated premium rise before market close.

 

Applications in Options Trading

• Expiry scalping: focusing on high gamma options in liquid indices like Nifty during the last hour, riding quick premium multiplication on breakouts.

• Event-driven plays: trading gamma blasts around earnings or policy announcements that trigger sharp underlying moves.

• OI, IV and volume: Using open interest (OI), volume, and IV changes to confirm momentum and timing entries.

This strategy depends critically on timing, volume confirmation, and IV spikes, exploiting gamma's accelerating effect on option prices in the final expiry session or during sharp events in liquid options markets

 

Gamma Blast Strategy for NSE Options Trading

The gamma blast strategy is a way for options buyers to make quick profits on India's NSE indices like Nifty  or Bank Nifty  when prices suddenly jump after staying flat, especially on expiry days.

 

Strategy Fundamentals

Gamma is like an "accelerator" for an option's price sensitivity (called delta). In at-the-money or slightly out-of-the-money options, high gamma (>0.002) causes the option premium to explode 2-3 times if the index breaks out sharply—think low volatility turning into a fast move, often after 1:45 PM on expiry

 

How to Spot and Trade It Simply

• Wait for calm markets (IndiaVIX under 15, price moves <1%, tight Bollinger Bands). 

• Check option chain for high open interest, low put-call ratio (<0.7 for bullish), and falling implied volatility. 

• Enter buys on volume breakout with IV spike;

• Example: Buy Nifty 22,100 call at Rs.50, sell at Rs.120 after 100-point rise for big gain.

 

Easy Steps Across Timeframes

Daily/Hourly: Look for squeezes, neutral RSI (40-60).

15/5-Min: Confirm MACD cross, volume pop past key levels.

Exit: By 3:15 PM with 30% stop-loss or 2x profit

 

Risks and Tips

Cap risk at 1-2% of capital; no overnight holds. Works less often on non-expiry days but possible with news like RBI updates, then use wider stops .

 

Risk Management Rules

• Stop-loss: 50 points or 30% premium loss. 

• Trail to breakeven post-2x. 

• Position size: 1-2% capital risk. 

• Exit by 3:15 PM to avoid slippage; no overnight holds. 

• Non-Expiring Adaptations Blasts happen mid-week with catalysts like RBI announcements or FII flows. 

• Adjust gamma threshold to >0.0015, entries 1:30-2:30 PM, wider stops of 75-100 points, targeting 1.5-2x at next HVN

Risks and Best Practices

• Limit to peak gamma periods like expiries or events.

• Select ATM/OTM with gamma above 0.002; apply tight stops to premium or points.

• Validate via option chains, OI decay, IV rises, and volume.

• Exit intraday to avoid overnight gaps.

Aim for gamma above 0.002 in ATM/OTM options with delta 0.3-0.5 for maximum premium explosion.

How do you manage risks in gamma blast?

Set 50-point or 30% premium stop-loss, risk just 1-2% capital, and exit by 3:15 PM always.

Can gamma blast work on non-expiry days?

Yes, but rarer, it needs news catalysts like RBI announcements; use looser stops at 75-100 points.
