NSE Option Chain Analysis: How It Works & What Does Indicate
In the stock market, apart from cash trading, there is another segment called derivatives where a huge volume of trades take place every day. Under the derivatives segment, Futures & Options are the value of cash market underlying stocks or indices. The “Option Chain” – is the word derived from here where it is widely used by traders to understand stocks.
What is Option Chain?
An option chain is a kind of option matrix showing the list of all contracts of an index or stock of any company. Option chain shows the calls and puts listed on the exchange with other details like the contract expiration date, strike price, volume, open interest and the last trading price of the underlying security or index with the maturity period of that contract.
Call and Put two types of options contracts are listed there, in which the call option gives you the right but not the obligation to buy for the underlying stock at a specified price and within the expiration date of that option. While on the other hand, the put option is a contract that gives you the right but not the obligation to sell the underlying stock at a specified price and within the expiration date of that option contract.
To read the option chain you need to understand its other components, and what and how each of the components shows the accumulated information of underlying stock. It simply provides detailed price information for each underlying stock on NSE.
How Option Chain Works?
The option chain works simply as per the price movement in the underlying stock or index. When the market starts with the number of trades the details of the option chain keep changing. And traders make their decisions according to the option price movement.

Call and Put options change with the change in the current market price of the stock. All other components are affected by the price and OI change. So before we move further let’s know about all the other components of the option chain.
Option Chain Analysis:
Strike Price: This is the price at which the buyer and seller of an option agreement exercise the contract. And when the price exceeds this strike price the option contract becomes profitable.
Last Trade Price: This is the price last time traded on the exchange and this LTP changes during market hours as per the change in the cash market price of the stock or index.
Ask Price: The asking price is the lowest price of the stock at which the seller of the stock is ready to sell the quoted security. Mostly the lowest ask price of any stock is quoted in the stock market for trading.
Bid Price: This is the highest price of the stock at which the buyer is ready to buy quoted stocks. This is the best market price a trader is ready to buy.
Bid Quantity: This is the quantity buyer is ready to buy the number of stocks at a specific strike price It is the latest demand for the strike price of an option.
Ask Quantity: It is the quantity seller is ready to sell the number quantity of stocks at a specific strike price. It is the availability of the option.
In-the-Money: When the strike price of a call option is smaller than the present market value then this option is called an in-the-money option. Conversely, when the strike price is greater than the current market price the option is called in-the-money.
Out-of-the-money: When a call option’s strike price is greater than the current market price of the underlying asset, then the option is out of the money. Similarly, in a put option, when the strike price is less than the current market price of an underlying stock, then it is considered an out-of-money option.
At-the-money: When the strike price of a call or put option is equal to the strike price of the market price of the underlying asset then it is called the at-the-money.
Open Interest (OI): Open interest generally shows the interest of the traders during a specific strike price that is visible through the open positions for a particular contract that is not yet closed or expired or not yet exercised.
Change in OI: It is the change in the open interest before the date of expiry of the contract. And the difference between the OI shows that either the contract is expired, closed, squared off or exercised by either party (buyer & seller).
Volume: The volume in the option chain is the number of contracts traded in the market for the particular strike price contract. The volume shows the liquidity in the market and helps to understand the current interest of the traders.
Implied Volatility: Implied volatility shows the swing of the price of the option chain. Higher implied volatility means a high swing in the price, while low implied volatility means a low swing in the price. This generally shows the volatility of call or put options.
