About NSE Option Chain
Overview of NSE Option Chain
An NSE Option Chain shows all the available call and put options for a stock or index listed on the National Stock Exchange. It helps traders quickly view strike prices, premiums, open interest, and other data in one place.
The layout is divided into two sides: calls on the left and puts on the right. By studying this data, traders try to understand where the market might go.
It is a useful tool to plan trades, spot key levels, and manage risks based on price movement expectations.
What is CE & PE in NSE Option Chain?
In the NSE Option Chain, you'll often see two types of options: CE and PE. These stand for Call Option (CE) and Put Option (PE).
A Call Option (CE) gives the buyer the right to buy the underlying stock or index at a fixed price before a set date. Traders buy call options when they think the price will rise. For example, if someone expects Nifty to rise, they may buy a Nifty call option.
A Put Option (PE) gives the buyer the right to sell the stock or index at a fixed price before expiry. This is often used when the expectation is that the price will drop.
So, in simple terms:
- Call Option (CE) = Profit when the price goes up
- Put Option (PE) = Profit when the price goes down
Key Components of NSE Option Chain
When you open an NSE Option Chain, it might look confusing at first. But once you know what each column means, it becomes much easier to read and use.
Here are the key components of the option chain that you need to understand:
- Strike Price: This is the price at which you can buy (call option) or sell (put option) the asset in the future. Traders choose strike prices based on how far they think the market will move.
- Call Option (CE) and Put Option (PE): The left side of the table shows data for Call Options, and the right side shows data for Put Options. Each row on both sides relates to the same strike price.
- Call Option (CE) gives the right to buy
- Put Option (PE) gives the right to sell
- Open Interest (OI): Open Interest shows how many option contracts are still active and not yet closed. High OI means many traders are interested in that level. A sudden increase in OI might mean new positions are being built.
- Change in Open Interest: This shows how much the OI has increased or decreased during the day. If OI is rising with the price, it often means new money is coming in. If OI is falling, people may be exiting their positions.
- Volume: Volume is the number of contracts traded on that day. More volume usually means more interest from traders.
- Implied Volatility (IV): This is the market's view of how much the asset's price might change in the future. If IV is high, option premiums go up. If it is low, premiums drop.
- Last Traded Price (LTP): It is the price at which the last trade happened for that option. It gives you an idea of the current value of that option.
- Bid Price and Ask Price: Bid Price is the price a buyer is willing to pay. Ask Price is the price a seller wants. The difference between the two is called the spread. When a spread is smaller, it means better liquidity.
- Net Change: It shows how much the price of the option has moved compared to yesterday's closing. Positive means it's up, negative means it's down.
Example of NSE Option Chain Data & How to Read It
To read it, start by locating the current spot price of the stock or index. Let's say you're looking at the option chain for NIFTY, and the current market price is around 19,850.
You notice the following entry:
Here's how to read it:
- Strike Price 20,000 is close to the current market level.
- On the Call side, open interest is high and it's increasing. This suggests that many traders are selling calls at 20,000, expecting the price to stay below it.
- On the Put side, even more traders are adding positions, which hints at support around this level.
By looking at this line, you can tell that 20,000 is acting as a key level. There seems to be resistance from call sellers and support from put buyers.
Reading such examples helps you spot strong zones where traders expect price movement to pause or reverse.
List of Indices in NSE Option Chain
So, here is a quick look at the indices available in the NSE Option Chain. These are not company stocks, but sets of stocks that represent a sector or segment of the market.
These indices help traders focus on specific sectors or take a broader market view using options. Most trading activity happens in Nifty 50 and Bank Nifty due to their high liquidity.
List of Stocks in NSE Option Chain (Top 5 by Liquidity & Popularity)
When people talk about the "top" stocks in the NSE option chain, they usually mean the ones with lots of trades and open positions. These stocks are easier to buy and sell (less slippage), and you will see more action in their options.
From current market data and listings of F&O stocks, here are five stocks that are often among the most liquid and popular for options trading in India:
- Reliance Industries: One of India's largest and most well‑known companies. Because many traders watch its movement, its options often see heavy volume and open interest.
- HDFC Bank: A big name in banking in India. Options in HDFC Bank tend to be active, as everybody watches what major banks are doing in relation to the economy and interest rates.
- ICICI Bank: As another leading private bank, it is often traded heavily. Its options are popular because it has enough volatility but also steady fundamentals.
- Tata Motors: In the auto / industrial sector, Tata Motors is one of the names that sees consistent option activity. Because many investors have interests in autos, its option chain is also active.
- Infosys: As a big tech / IT name, it gets attention whenever markets move. Its options get traded heavily when markets are sensitive to global tech trends, policy news, etc.
Note: These are not fixed forever. The "top 5" can change with market trends, sectoral shifts, or news events.
Understanding Expiries in NSE Option Chain
In options trading, expiry means the last day on which an options contract can be traded. After this date, the contract becomes invalid.
In the NSE Option Chain, understanding when different options expire is very important, especially if you're planning to trade weekly or monthly options.
Here's what you need to know:
Now you must be wondering when options contracts expire. What day of the month is it? Well, it's not just which day of the month, but also which weekday. The rules have changed recently, so this part is especially important.
In the past, many index and stock options expired on Thursdays (for example, the last Thursday of the month). But now, because of regulatory changes from SEBI and new exchange policies, expiry days are being adjusted.
For instance, from September 1, 2025, the new index expiry series (for Nifty) will use Tuesday as the expiry weekday (for weekly and monthly contracts).
Stock option expiries will also shift to Tuesday (for new contracts) from their earlier Thursday expiries.
If the scheduled expiry day is a holiday, the expiry is moved to the previous trading day.
Frequently Asked Questions (FAQs)
