What is delta?
In order to learn about gamma and gamma scalping, you must first get an understanding of delta.
Delta reflects the sensitivity of an option’s price to variations in the underlying asset’s value. It measures the change in an option’s price for a one-unit change in the underlying asset’s price.
Delta values range from -1 to +1 for puts and calls, respectively.
- A delta of +1 indicates a direct correlation between the option’s price and the underlying asset’s price.
- A delta of -1 suggests an inverse relationship.
Delta also serves as an estimate of the probability that an option will expire in-the-money, with a higher delta indicating a higher likelihood of in-the-money expiration.
“In-the-money expiration” refers to an options contract having intrinsic value at its expiration.
For call options, it occurs when the underlying asset’s market price is higher than the option’s strike price. For put options, it occurs when the underlying asset’s market price is lower than the option’s strike price. Traders can increase their return by exercising or selling these options at expiration.

What is delta scalping?
Briefly speaking, delta scalping is a trading strategy used by experienced traders in options and futures markets. It involves closely monitoring the delta of a contract, which indicates its price sensitivity to the underlying asset’s movement.
Traders buy the contract when the delta is positive and sell when it’s negative, aiming to get good returns from short-term price fluctuations. It requires quick decision-making and risk management.
What is gamma?
Gamma measures how fast an option’s delta changes when the underlying asset’s price moves. It shows how sensitive the option’s price is to changes in the underlying asset’s value.
A high gamma value indicates greater delta sensitivity and more significant price fluctuations, while a low gamma value suggests less delta sensitivity and smaller price movements.
What is gamma scalping?
Gamma represents the rate of change in an option’s delta in response to underlying asset price changes. Gamma scalping is an options trading strategy where traders adjust their options positions to maintain a neutral gamma exposure. The neutral gamma implies a position or portfolio of options contracts where the overall gamma value is approximately zero.
The goal of gamma scalping is to receive good returns from short-term price movements of options by taking advantage of changes in gamma and delta.
You must be wondering “what is delta?”
So, let us discuss the meaning of delta briefly and then proceed.
Formula of gamma scalping
The formula Δ = Γ * ΔS expresses the relationship between delta, gamma, and the change in the underlying asset’s price. Gamma amplifies the impact of price movements on an option’s delta.
In this formula,
- Δ represents the change in the option’s delta
- Γ represents gamma and
- ΔS represents the change in the underlying asset’s price.
Essentially, gamma magnifies the impact of price movements on an option’s delta. The core concept of gamma scalping involves continuously adjusting options positions to maintain a neutral gamma exposure, thus capitalising on short-term price movements while managing risk effectively.
Example of gamma scalping
Let us learn gamma scalping with an example.
John is a trader with a portfolio of options that has a neutral gamma position. If the price of the underlying asset increases, the gamma of the options also increases. To maintain a neutral gamma exposure, John would sell some options to offset the increased gamma. This allows the trader to secure good returns and maintain the desired risk level.
On the other hand, if the price of the underlying asset decreases, the gamma of the options decreases as well. In this scenario, John would purchase additional options to rebalance the gamma exposure. This enables the trader to benefit from the falling prices and potentially retrieve good returns from subsequent price rebounds.
In brief:
In gamma scalping, traders actively monitor the gamma of their options positions for an increase or decrease in gamma.
Price of underlying asset goes up, gamma of options also goes up:
In this case, the trader sells some options to offset the increased gamma.
Price of underlying asset goes down, gamma of options also goes down:
In this case, the trader buys some options to rebalance the gamma exposure.
Steps to use gamma scalping in trading
To effectively utilise gamma scalping in trading, it’s important to follow a systematic approach. In this section, we will explore a step-by-step guide on how to use gamma scalping in your trading strategy. These steps will provide you with a solid foundation to implement and adapt the strategy based on market conditions and your risk management preferences.
Let’s dive in and discover how to implement gamma scalping:
Understand Gamma and Delta
Familiarise yourself with the concepts of gamma and delta. Gamma represents the rate of change in an option’s delta in response to changes in the underlying asset’s price. Delta measures the sensitivity of an option’s price to changes in the underlying asset’s price.
Choose an Underlying Asset
Select an underlying asset that exhibits sufficient volatility and liquidity. Stocks, indexes, or exchange-traded funds (ETFs) are common choices for gamma scalping.
Set Up Options Positions
Establish a portfolio of options positions with a neutral gamma exposure. This typically involves combining long and short options contracts to offset gamma effects and maintain a gamma-neutral stance.
Monitor Gamma Exposure
Regularly monitor the gamma exposure of your options positions. Use options pricing models or online platforms to track changes in gamma as the underlying asset’s price moves.
Risk Management
Implement risk management techniques such as setting stop-loss orders to limit potential losses. Regularly review and adjust stop-loss levels as market conditions evolve.
Market Monitoring
Stay informed about market conditions, including volatility, upcoming events, and economic news that could impact the underlying asset. This information helps you make informed decisions and adjust your gamma scalping strategy accordingly.
Regular Evaluation
Continuously evaluate the performance of your gamma scalping strategy. Analyse historical data, track the effectiveness of adjustments and refine your approach based on market conditions and feedback.
Practice and Learn
Like any trading strategy, practice and experience are essential for success. Start with small positions and gradually increase your exposure as you gain confidence and refine your skills.
Gamma scalping in trading with Python
Let us check out the gamma scalping strategy in trading with Python now.
Import the libraries
Read data
Here we collect the data from nseindia and save it as a CSV File.
Calculate time to expiry
We convert the trading date (‘Date’) and expiry date (‘Expiry’) into a datetime object and then, calculate and store the time to expiry in days.
Determine ATM strike price
In this step, we determine the ATM strike price of the option. We will consider the strike price nearest to the future price to be ATM. This step is required so that we can take positions in the ATM straddle.
After this, you compute the implied volatility, delta and plot the daily delta.
Then, you will compute the strategy PnL with these steps:
Compute the strategy PnL
The steps followed to compute the strategy PnL are as follows:
- PnL from the straddle (Call PnL + Put PnL)
- PnL from the Nifty futures
- Strategy PnL = straddle PnL + Nifty futures PnL
The strategy PnL will be visualised like this:
This graph above shows that the strategy helped with good returns over a period of time. The cumulative returns made through this strategy are INR 1000.

Traders may utilise one or both strategies based on their specific needs such as risk management approach, preferring to go long or short, etc. and market outlook such as high volatility, directional bias, etc.
Risk management with gamma scalping
Risk management plays a vital role in gamma scalping, where traders actively manage options positions to maintain a neutral gamma exposure.
Traders should have a comprehensive understanding of the risks involved, monitor positions diligently, and adapt risk management techniques accordingly to maintain a disciplined and controlled trading approach and avoid heavy losses.
Here are some of the risk management techniques that can be used with gamma scalping:
Position Sizing
Determine an appropriate position size based on risk tolerance and account size. Avoid overexposure by ensuring your positions are not too large, in order to reduce the potential for significant losses.
Implement Stop-loss Orders
Use stop-loss orders to define exit points if the market moves unfavourably. Set predetermined price levels to limit potential losses and regularly review and adjust them as market conditions change.
Monitor Gamma Exposure
Continuously monitor the gamma exposure of options positions. Excessive gamma exposure can increase risk during volatile market conditions. Regularly rebalance and adjust positions to maintain a neutral gamma exposure and mitigate risk.
Manage Volatility
Stay vigilant about underlying asset volatility. Higher volatility increases the risk of larger price swings and potential losses. Consider adjusting position sizes, utilising appropriate option strategies, or implementing risk mitigation techniques during periods of elevated volatility.
Embrace Diversification
Maintain a diversified portfolio of options positions across different underlying assets and expiration dates. Diversification helps spread risk and minimises the impact of adverse price movements in a single asset.
Regular Evaluation and Adjustments
Continuously evaluate the performance of the gamma scalping strategy and make necessary adjustments. Analyse historical data, assess the effectiveness of position adjustments, and refine the approach based on market conditions and real-time feedback.
Assess Risk/Reward Ratio
Evaluate the risk/reward ratio for each trade. Seek trades with a favourable risk/reward profile, where potential returns outweigh potential losses. This ensures a positive expected value over the long term.
Pros of gamma scalping
Gamma scalping provides several advantages for options traders. Here are the pros of gamma scalping:
Capitalise on Short-Term Price Movements
Gamma scalping enables traders to maximise returns from short-term price fluctuations in the underlying asset. By actively adjusting options positions based on changes in gamma and delta, traders can take advantage of rapid price movements.
Risk Management
Maintaining a neutral gamma exposure in gamma scalping helps manage risk. Traders can rebalance their options positions to limit potential losses and mitigate the impact of adverse price movements. This risk management aspect is especially beneficial in volatile markets.
Flexibility and Adaptability
Gamma scalping provides flexibility as traders can adapt their positions to different market conditions. Whether the market is trending up, down, or sideways, traders can adjust their options positions accordingly to capitalise on short-term price changes.
Exploit Volatility
Gamma scalping thrives in volatile markets. Higher price volatility leads to larger changes in gamma, creating more opportunities of maximising returns. Traders can actively respond to and exploit price volatility through dynamic adjustments of options positions.
Enhance Options Trading Skills
Implementing gamma scalping improves traders’ understanding of options and their sensitivities, such as gamma and delta. Traders gain practical experience in adjusting positions, managing risk, and interpreting market dynamics, thereby enhancing their overall options trading skills.
Diversification Benefits
Gamma scalping allows for diversification across multiple options positions and underlying assets. Spreading positions across various assets, expiration dates, and strike prices helps reduce the impact of adverse price movements in a single asset, potentially enhancing risk-adjusted returns.
Real-Time Feedback
Gamma scalping is an active strategy that provides immediate feedback. Traders can monitor market conditions, make timely adjustments, and receive real-time feedback on the effectiveness of their strategy. This allows for continuous learning and refinement of the approach.
It’s essential for traders to recognise that while gamma scalping offers advantages, it also carries risks. Traders should carefully assess market conditions, implement proper risk management techniques, and adapt the strategy to their individual trading goals and risk tolerance.

FAQs on gamma scalping
Gamma scalping might be a bit confusing for some of us. Let’s go through a few commonly asked questions to improve our understanding.
What is the positive gamma?
Positive gamma occurs when the gamma value of an options position is greater than zero. It means that the rate of change in the delta increases as the underlying asset price moves.
What is the negative gamma?
Negative gamma occurs when the gamma value of an options position is less than zero. It means that the rate of change in the delta decreases as the underlying asset price moves.
What is the short gamma position?
A short gamma position refers to having a net negative gamma exposure. It means the options position is more sensitive to changes in the underlying asset price, resulting in higher risk and potential losses if the market moves unfavourably.
What is the long gamma position?
A long gamma position refers to having a net positive gamma exposure. It means the options position is less sensitive to changes in the underlying asset price, providing potential opportunities for maximising returns if the market moves in the desired direction.
