Gamma trading
- Gamma Trading
Gamma trading is an advanced options strategy that aims to profit from changes in an underlying asset's price, specifically focusing on the rate of change of the Delta of an option. While often discussed in the context of stock options, the principles can be adapted – with careful consideration – to the realm of Binary Options. This article provides a comprehensive introduction to gamma trading, its mechanics, risks, and potential applications within binary options trading.
What is Gamma?
Before diving into the strategy, it's crucial to understand Gamma. Gamma measures the *rate of change* of an option’s Delta for every one-point move in the underlying asset's price.
- **Delta:** Delta represents the sensitivity of an option’s price to a one-dollar change in the underlying asset’s price. It ranges from 0 to 1 for call options and -1 to 0 for put options.
- **Gamma:** Gamma tells us how much Delta will change when the underlying asset moves. A high Gamma means Delta is highly sensitive to price changes, while a low Gamma means Delta is relatively stable.
Gamma is highest for at-the-money options (options with a strike price close to the current price of the underlying asset) and decreases as the option moves further in-the-money or out-of-the-money.
Option Position | Gamma |
Long Call | Positive |
Long Put | Positive |
Short Call | Negative |
Short Put | Negative |
Understanding the Gamma Profile
The Gamma profile visually represents the Gamma of an option across different strike prices. Typically, it resembles an inverted U-shape. Options closest to the current price of the underlying asset have the highest Gamma, while options further away have lower Gamma.
Gamma Neutral Strategies
Gamma trading often involves establishing a *Gamma neutral* position. This means combining options positions to create a portfolio with a net Gamma of zero. The goal isn’t necessarily to profit from a directional move in the underlying asset but to profit from changes in volatility or to take advantage of the decay of time value (Theta) while minimizing directional risk.
A classic Gamma neutral strategy involves combining a long and a short option with different strike prices. For example:
- Buy one call option with a lower strike price.
- Sell two call options with a higher strike price.
This combination aims to neutralize the portfolio’s Gamma, making it less sensitive to small price movements. However, it’s rarely *perfectly* Gamma neutral due to the dynamic nature of Gamma itself.
Gamma Scalping
Gamma scalping is a more active strategy that involves continuously adjusting a Gamma neutral position to maintain neutrality as the underlying asset’s price moves. This is typically done by:
1. Monitoring the portfolio’s Delta. 2. Adjusting the position (buying or selling options) to keep Delta near zero.
This requires frequent trading and a deep understanding of options Greeks. It’s a short-term strategy designed to profit from small price fluctuations and the decay of time value. Volatility Trading is often a key component of gamma scalping.
Gamma Trading in Binary Options: Challenges and Adaptations
Applying Gamma trading principles directly to Binary Options is challenging because binary options have a fixed payout structure and no continuous Delta. However, the *concept* of exploiting changes in price sensitivity can be adapted.
Here's how:
- **Multiple Expiry Times:** Utilize binary options with different expiry times. A shorter expiry time will have a higher sensitivity to immediate price movements (analogous to high Gamma), while a longer expiry time will be less sensitive.
- **Strike Price Selection:** Choose strike prices that are close to the current market price (at-the-money). These options will be most sensitive to price changes.
- **Hedging with Opposing Binary Options:** While a direct Gamma neutral hedge isn’t possible, you can construct a position that profits from increasing or decreasing price volatility. This might involve simultaneously buying a Call option and selling a Put option (or vice versa) with the same expiry time, but careful consideration of risk/reward is essential.
- **Volatility Assessment:** Accurate Volatility Analysis is crucial. Gamma trading thrives in periods of increasing volatility. Tools like the ATR (Average True Range) indicator can help assess volatility.
- **Dynamic Adjustment:** Similar to gamma scalping, continuously monitor the market and adjust your positions based on price movements and changes in implied volatility. Technical Analysis is essential for this.
- Important Considerations for Binary Options:**
- **All-or-Nothing Payout:** Binary options offer a fixed payout or nothing. This makes precise timing and accurate predictions critical.
- **Limited Profit Potential:** The fixed payout limits the potential profit compared to traditional options.
- **High Risk:** Binary options are inherently risky. A small adverse price movement can result in a complete loss of investment.
- **Broker Regulations:** Ensure your broker is properly regulated and offers transparent trading conditions.
Example Scenario (Binary Options Adaptation)
Let's say the current price of an asset is $100. You believe volatility is about to increase.
1. **Buy a Call option** with a strike price of $100 expiring in 30 minutes. (Cost: $50) 2. **Sell a Put option** with a strike price of $100 expiring in 30 minutes. (Receive: $40)
This is *not* a true Gamma neutral hedge. Instead, it's a bet that the price will move significantly in either direction. If the price moves substantially up or down, one of the options will likely expire in-the-money, generating a profit. If the price remains relatively stable, both options may expire out-of-the-money, resulting in a loss. This strategy relies on an increase in volatility to move the price beyond the breakeven point.
Risks of Gamma Trading
Gamma trading is a complex strategy with significant risks:
- **Volatility Risk:** Unexpected changes in volatility can quickly erode profits.
- **Time Decay (Theta):** Options lose value as they approach their expiration date. This is especially critical in short-term Gamma scalping strategies. Understanding Theta Decay is paramount.
- **Transaction Costs:** Frequent trading generates transaction costs (brokerage fees, spreads) that can eat into profits.
- **Model Risk:** Relying on theoretical models (like the Black-Scholes model) can be inaccurate, especially in volatile markets.
- **Whipsaws:** Rapid, erratic price movements can trigger losses even in a Gamma neutral position.
- **Liquidity Risk:** Limited liquidity in certain options markets can make it difficult to execute trades at desired prices.
- **Binary Options Specific Risks:** The all-or-nothing nature of binary options amplifies the risks associated with incorrect predictions.

- **Veta:** Measures the rate of change of Vomma.
- **Delta Hedging:** A strategy to neutralize Delta by continuously adjusting the position in the underlying asset.
- **Pairs Trading:** Exploiting price discrepancies between related assets. Correlation Trading is closely related.

Conclusion
Gamma trading is a sophisticated strategy that requires a thorough understanding of options Greeks, market dynamics, and risk management. While direct application to binary options is limited, the underlying principles of exploiting price sensitivity and volatility can be adapted with caution. Remember to start with small positions, practice proper risk management, and continuously educate yourself before attempting this strategy. Always consider the inherent risks of Binary Options Trading and trade responsibly.
