Related Terminology in Options Screener: A Comprehensive Guide

An options screener is a powerful tool that helps traders filter and identify potential options trades based on specific criteria. However, to use an options screener effectively, it’s essential to understand the terminology associated with it. This article will explore key terms commonly found in options screeners, providing detailed explanations to help you make informed trading decisions. Whether you are new to options trading or an experienced trader looking to refine your strategies, understanding these terms will enhance your ability to navigate the options market.

What Is an Options Screener?

An options screener is a tool provided by many brokerage platforms and financial websites that allows traders to search for and analyze options contracts based on various criteria. These criteria can include factors like expiration dates, strike prices, implied volatility, and other technical indicators. By using an options screener, traders can quickly identify opportunities that match their trading strategies and risk tolerance.

Key Terminology in Options Screeners

1. Underlying Asset

• Definition: The underlying asset is the financial instrument (such as a stock, ETF, or index) upon which an options contract is based. The value of the options contract is derived from the price of this underlying asset.

• Importance: When using an options screener, selecting the underlying asset is the first step in narrowing down potential trades. The performance of the underlying asset directly affects the price and profitability of the option.

2. Strike Price

• Definition: The strike price, also known as the exercise price, is the price at which the holder of the option can buy (in the case of a call option) or sell (in the case of a put option) the underlying asset.

• Importance: The strike price is a critical factor in determining the option’s profitability. Traders often use the options screener to find contracts with specific strike prices that align with their market outlook.

3. Expiration Date

• Definition: The expiration date is the last day on which the option can be exercised. After this date, the option becomes worthless if it is not in the money.

• Importance: The time remaining until expiration affects the option’s time value. Options screeners allow traders to filter contracts based on expiration dates, which is crucial for time-sensitive strategies.

4. Implied Volatility (IV)

• Definition: Implied volatility is a measure of the market's expectation of future volatility in the price of the underlying asset. It reflects the market's view of how likely it is that the underlying asset’s price will fluctuate.

• Importance: Higher implied volatility generally leads to higher option premiums. Traders use implied volatility to gauge market sentiment and to identify options that may be over or underpriced. Many options screeners include filters for implied volatility to help traders identify opportunities based on volatility expectations.

5. Delta

• Definition: Delta is one of the option Greeks and measures the sensitivity of an option's price to changes in the price of the underlying asset. It represents the change in the option’s price for a $1 change in the price of the underlying asset.

• Importance: Delta helps traders understand the likelihood of an option expiring in the money. A delta close to 1 indicates that the option is deep in the money, while a delta close to 0 indicates it is out of the money. Options screeners often include delta as a filter to help traders find options with specific risk-reward profiles.

6. Gamma

• Definition: Gamma is another option Greek that measures the rate of change of Delta with respect to changes in the underlying asset's price. It indicates how much the Delta will change for a $1 move in the underlying asset.

• Importance: Gamma is important for understanding how the risk of an options position changes as the price of the underlying asset moves. High Gamma means that Delta can change quickly, leading to more significant price swings in the option. Options screeners may provide Gamma as a filter for traders who want to understand the potential volatility of their options positions.

7. Theta

• Definition: Theta represents the time decay of an option, showing how much the price of an option decreases as time passes, assuming all other factors remain constant.

• Importance: Theta is crucial for traders, especially those who hold options positions over time. A high Theta means that the option's value will decrease rapidly as expiration approaches. Options screeners often allow traders to filter by Theta to find options that align with their time horizon.

8. Vega

• Definition: Vega measures the sensitivity of an option's price to changes in the implied volatility of the underlying asset. It indicates how much the price of an option will change for a 1% change in implied volatility.

• Importance: Vega is particularly important in volatile markets. Traders use Vega to assess how changes in volatility might impact their options positions. Options screeners with Vega filters help traders find options that could benefit from expected changes in market volatility.

9. Open Interest

• Definition: Open interest refers to the total number of outstanding options contracts that have not been settled. It represents the level of activity and liquidity in a particular options contract.

• Importance: High open interest indicates a liquid market, making it easier to enter or exit positions without significant price impact. Options screeners often include open interest as a filter to help traders find contracts with sufficient liquidity.

10. Volume

• Definition: Volume refers to the number of options contracts traded during a specific period, typically within a single trading day.

• Importance: High trading volume suggests strong interest in an options contract, which can lead to tighter bid-ask spreads and better execution prices. Traders use volume filters in options screeners to identify contracts with high trading activity.

11. Bid-Ask Spread

• Definition: The bid-ask spread is the difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask) for an options contract.

• Importance: A narrow bid-ask spread indicates a more liquid market and can lead to better trade execution. Wider spreads can increase trading costs. Options screeners can help traders find contracts with favorable bid-ask spreads.

12. Intrinsic Value

• Definition: Intrinsic value is the difference between the current price of the underlying asset and the strike price of the option, but only for in-the-money options. For a call option, it’s the amount by which the asset’s price exceeds the strike price; for a put option, it’s the amount by which the strike price exceeds the asset’s price.

• Importance: Intrinsic value represents the real, tangible value of an option if it were exercised immediately. Traders use options screeners to identify options with significant intrinsic value, which are often less risky than options with only extrinsic (time) value.

13. Extrinsic Value

• Definition: Extrinsic value, also known as time value, is the portion of an option's price that exceeds its intrinsic value. It reflects the potential for the option to become more valuable before expiration due to factors such as time remaining and implied volatility.

• Importance: Extrinsic value is crucial for understanding the potential upside (or downside) of holding an option until expiration. Options screeners can help traders find options with high extrinsic value if they are betting on significant market moves or volatility changes.

14. Probability of Expiring In-The-Money (ITM)

• Definition: This metric represents the likelihood that an option will expire in the money, based on current market conditions, implied volatility, and time to expiration.

• Importance: Traders use this probability to assess the potential success of their trades. Options screeners that include this filter allow traders to focus on options with a higher chance of profitability.

15. Delta Neutral Strategy

• Definition: A Delta neutral strategy involves creating a portfolio of options and/or underlying assets that has a net Delta of zero, meaning that the portfolio’s value is relatively insensitive to small price movements in the underlying asset.

• Importance: Delta neutral strategies are used to manage risk and reduce the impact of short-term price fluctuations. Options screeners can help identify options that can be used to construct Delta neutral portfolios.

How to Use an Options Screener Effectively

1. Define Your Strategy

   • Before using an options screener, clearly define your trading strategy. Are you looking for high-probability trades, hedging opportunities, or speculative positions? Knowing your goals will help you set the right filters.

2. Set Appropriate Filters

   • Use the options screener to apply filters that match your strategy. For example, if you’re looking for high-volatility trades, set filters for implied volatility and Vega. If you’re focused on liquidity, use filters for open interest and volume.

3. Analyze the Results

   • Once the screener provides a list of options, analyze the results in detail. Consider factors like the bid-ask spread, Delta, and probability of expiring ITM. Make sure the options align with your strategy before executing any trades.

4. Monitor Continuously

   • Markets are dynamic, and options prices can change quickly. Use the screener regularly to stay updated on new opportunities and to adjust your positions as needed.

Conclusion

Understanding the related terminology in options screeners is essential for making informed and effective trading decisions. By familiarizing yourself with key terms such as underlying asset, strike price, implied volatility, Delta, and others, you can use an options screener to identify trades that align with your strategy and risk tolerance. Whether you are managing risk, seeking profit opportunities, or building complex strategies, the knowledge of these terms will empower you to navigate the options market with confidence.
