Introduction
What is an option in stock trading?
An option is a contract that allows the owner to trade, i.e. buy or sell a certain asset at a strike price by the expiration date. It is important to note that the owner is not required to take any action but can do so if they choose. There are two main types of options:
- Call option: Call options are typically used when a holder expects the underlying asset's price to rise.
- Put option: Put options are used when a holder expects the underlying asset's price to fall.
Usually, stock traders use options for hedging price fluctuations, assuming price movements, and managing risk in dynamic financial markets.

What is an option chain widget in a stock trading platform?
An option chain widget is a tool or interface used in trading platforms to display a list of available options contracts for a particular underlying asset. It provides traders with essential information about various options, including strike prices, expiration dates, bid-ask prices, and other relevant data. Traders can use this widget to select and trade options that align with their investment strategies.
An option chain widget typically displays columns for both call and put options. These columns are essential for traders to make informed decisions and analyze the available options contracts. Here are the most common columns in an option chain widget:
Column | Description |
---|---|
Instrument name | Name or symbol of the underlying asset |
Expiry date | Date when the options contracts expire |
Option type | Indicates call (C) or Put (P) option |
Strike price | The price at which the traders can exercise the options |
Last trade price (LTP) | The most recent traded price of the option |
Net change | Difference between LTP and the previous day's close |
Bid quantity | Number of contracts buyers are willing to buy |
Bid price | The price at which traders are inclined to buy |
Ask quantity | Number of contracts traders are inclined to sell |
Ask price | The price at which sellers are willing to sell |
Open interest (OI) | Total outstanding contracts for a specific strike and expiry |

Guidelines to create an efficient option chain widget for a trading platform
For traders, having access to accurate and up-to-date information is paramount in today's fast-paced financial markets. So, creating an efficient option chain widget requires a deep understanding and a commitment to data accuracy. At Evoqins, we follow these steps:
- Know your audience: Before delving into the technicalities, it's vital to comprehend your target audience β the traders and investors who will engage with your platform. Consider their expertise levels, trading strategies, and inclinations. Do they prefer day trading, swing trading, or long-term investing? Tailoring your option chain widget to its requirements is fundamental for its success.
- Data accuracy and speed: The lifeblood of any trading platform is precise, real-time data, and your option chain widget is no exception. Ensure that your widget can rapidly and accurately fetch and display data. Implement robust data validation mechanisms and error-handling protocols to prevent misleading information from reaching your users.
- User-friendly interface: A cluttered and bewildering interface can deter users. Keep your widget's design intuitive and uncluttered. Provide options for users to filter and personalize data to match their preferences. Consider the inclusion of tooltips and clear labels to explain various data points and terms, especially for novice traders.
- Mobile responsiveness: Ensure your option chain widget is responsive to mobile device resolutions, guaranteeing an optimal customer experience on smartphones and tablets.
- Interactive charts: Integrate interactive charts that enable users to visualize price movements and historical data. Candlestick, line, and bar charts can assist traders in spotting trends and making informed decisions. Incorporate zoom and pan features for detailed analysis.
- Option chain customization: Empower users with the ability to customize the option chain view. They may want to access additional data points such as open interest, implied volatility skew, or historical volatility. Offering such customization options will set your widget apart.
- Testing and feedback: Conduct comprehensive testing before launching your option chain widget to ensure its reliability and performance. Seek feedback from traders and incorporate improvements based on their valuable insights.
- Security and compliance: Trading platforms handle sensitive financial data, necessitating robust security measures and strict adherence to regulatory requirements. Encrypt user data and fortify protection against unauthorized access.
Conclusion
In summary, creating an efficient option chain widget demands a profound understanding of your users, an unwavering commitment to data precision, and a user-friendly design. You can craft a widget that elevates the trading experience for your clients, leading to increased user engagement and satisfaction by adhering to these guidelines. Keep in mind that financial markets continually evolve; thus, staying informed about industry trends and consistently enhancing your option chain widget is crucial for meeting the changing needs of traders and investors.
