How to understand option chain data – When it comes to trading options, there are many different factors that can affect an investor’s overall strategy. From time decay to implied volatility, there is a wide variety of inputs that can have an impact on the potential for profit.
Understanding these factors and how they apply to a specific strategy is key in order to create a robust and profitable options trading plan. With so many variables at play within the world of options, it can be difficult to know exactly what information is essential and what you can ignore.
The truth is that every bit of information helps you gain a deeper understanding of your chosen strategy and its risks. In this article, we’ll explore some commonly used option chain data and explain when it’s best to trade specific options rather than others.
What is an option chain data?

An option chain is a graphical representation of option prices. Traders use these chains to help determine the potential profit or loss of any given strategy.
They can be used to analyze both Calls and Puts, but the actual data will depend on whether you are looking at a put chain or call chain.
Chains are typically presented in either a table or graph format. You will see several different inputs within the table, including the underlying security, expiration date, type of option (Call or Put), strike price, and the current price of the option.
How to read option chain data – concept of chains and the Greeks
An option chain contains a number of different data points, which can be broken down into five categories
Underlying security: The underlying security is the stock or asset that the option is based on. If you are trading a call, this refers to the stock that you expect the price of the call to rise above the strike price. If you are trading a put, this refers to the underlying stock that you expect the price of the put to fall below the strike price.
Expiration date: The expiration date determines when the option will no longer be valid. This means that the investor will no longer be able to sell or buy the underlying stock. Because an option’s price is affected by time, it is important to keep track of the expiration date so you can know when the option will stop having value.
Type of option: The type of option refers to whether the option is a call or put. Calls represent the right to buy the underlying stock, while puts represent the right to sell the underlying stock.
Strike price: The strike price is the price at which the option can be executed and the underlying stock can be bought or sold. This price is an important factor in calculating the potential profit or loss of an option.
The Greeks: These include input factors that affect the price of an option. They include the time value, volatility, and the risk-free rate.
Implied volatility trading strategies
As we’ve discussed, implied volatility is a measurement of the expected price movement of a given option.
This volatility measurement helps you to understand when you can expect an option’s price to be stable or volatile.
Volatility is usually higher when the market is closed, so it’s a good idea to wait until the trading day re-opens before making any changes to your trading strategy.
When you are looking at an option chain and the implied volatility is high, this means that the market expects significant price movement for that particular option.
In this case, you would want to avoid this option because it is most likely to take a large amount of time to reach the strike price.
In contrast, when the implied volatility is low, this means that the market expects little price movement for that option.
In this scenario, you would want to wait until the volatility increases before you make a trade because the price should move quickly towards the strike price.
Best Times of the Day To Buy and Sell Stocks
Option chains provide you with the opening, high, low, and closing prices of a given option. These prices help you to understand the potential profit or loss of the option.
The best time to trade an option is when the price is close to the low mark. When the prices are at the high mark, the option will be near its expiration date, which means that it will start losing value quickly.
At the same time, when the prices are at the low mark, the option has a high chance of expiring worthless.
In order to avoid these outcomes, you should avoid purchasing an option when the price is at the high mark and avoid selling an option when the price is at the low mark.
Option chain data – Breaks and Expiration
A break happens when the price of an option significantly deviates from its expected price. In this case, the option will be deemed as broken, which means that it no longer has value.
You can tell when an option is broken by looking at the chain and seeing if the price is significantly different from the other option prices.
While there is nothing you can do to prevent a break, you can keep track of which options have a high chance of breaking. This information can be helpful when you are trying to decide which options to sell in order to minimize your loss.
Volume DataVolume is a measurement of how many shares of an underlying security have been traded. Traders will keep track of the volume of the options that are available on an option chain.
Keep in mind that the volume of options will not be the same as the volume of the underlying security. When the volume of the underlying security is high, the volume of the options will be high as well.
This means that the options have high demand, which could impact the overall pricing of the option and affect your potential profit or loss.
When you see that the volume for the underlying security and the volume for the options are high, this means that it is a good time to avoid trading options.
When the volume for the underlying security and the volume for the options are low, this means that it is a good time to trade options.

Frequently asked questions (faq)
What is pcr in option chain ?
