What is Option Chain?
An option chain (also known as an options matrix) is a detailed table that displays all available options contracts for a particular stock or index. It includes essential data such as:
Strike prices: The price at which the option can be exercised.
Expiry dates: When the option contract will expire.
Premiums: The price you pay for buying an option.
Open interest (OI): The total number of outstanding contracts.
LTP (Last Traded Price): The last price at which the option was traded.
Bid and Ask: The highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask).
Volume: The total number of contracts traded during the day.
For example, when you look at the NSE option chain (National Stock Exchange), you’ll find all the essential data on Nifty 50 options, stock trading options, and individual F&O stocks.
How to Read an Option Chain?
Strike Price
At the core of an option chain are the strike prices. These are predetermined prices at which the option can be bought or sold upon expiry. The strike prices usually run down the middle of the option chain.
If you believe the price of the underlying asset will rise, you might buy a call option, while if you think the price will fall, you might purchase a put option.
Call and Put Options
In an option chain, you’ll typically see two columns: one for call options and one for put options. Calls are on the left side of the table, while puts are on the right.
A call option gives the buyer the right, but not the obligation, to buy an asset at a specific price before the contract expires. A put option gives the buyer the right to sell.
Expiry Dates
Each option contract comes with a specific expiry date. As you go through the option chain, you’ll see contracts for various expiry dates, such as weekly, monthly, or quarterly. Shorter expiry dates are riskier but may offer higher returns.
What is OI in Option Chain?
Open interest or OI refers to the total number of open or outstanding contracts for a particular strike price. This metric is essential because it provides insight into market sentiment. A higher OI usually indicates strong interest in a specific strike price, which can help traders predict price movements.
What is LTP in Option Chain?
The LTP or Last Traded Price is the most recent price at which the option was traded. This figure helps you understand how an option is moving in real time and whether there is the buyer or seller momentum.
Volume
Trading volume represents the number of option contracts traded within a given period, typically during a trading session. The highest volume in option chain meaning is significant because it often points to increased trader interest at a specific strike price, possibly indicating where the stock is headed in the short term.
What is Bid and Ask in Option Chain?
The bid price is the maximum price a buyer is willing to pay for an option, while the ask price is the minimum a seller is willing to accept. Understanding the bid-ask spread is crucial for gauging liquidity. A tighter spread often indicates a more liquid market.
How to Analyse Option Chain?
When it comes to analysing an option chain, start by looking at open interest and volume. These two metrics can provide valuable insights into market sentiment. If a strike price shows high OI and trading volume, that level is likely a significant point of support or resistance.
Next, pay attention to the LTP and bid-ask spread. A rising LTP with a narrow bid-ask spread often indicates strong buyer interest. Conversely, if the LTP is falling and the spread is widening, sellers may be dominating the market.
How to Interpret OI and Volume?
What is open interest in options, and how does it differ from volume? While volume indicates how many contracts have been traded in a given session, open interest shows how many contracts are still open. Higher OI at a specific strike price often indicates that market participants believe the price will move toward that level.
For example, if you see a high OI in Nifty 50 options at a particular strike price, it could mean that traders are expecting the index to reach that level by the expiry date.
How to Trade Using Option Chain?
Now that you know the basics of how to interpret option chain, let’s talk about how to trade using an option chain.
Identify Trends
Use open interest and volume to spot trends in the market. A sudden surge in OI at a particular strike price could signal a significant move.
Check Volatility
Before making a move, consider implied volatility, which can affect option pricing. Higher volatility increases premium prices.
Monitor LTP
Keep an eye on the LTP to gauge market direction. If the LTP is rising for a call option, it suggests bullish sentiment. Conversely, a rising LTP for a put option indicates bearish sentiment.
Consider Expiry Dates
Short-term options can offer quick profits but come with higher risks, especially due to time decay (theta). Longer-term options are generally less risky but offer slower returns.
A trading app allows you to view option chains and assess real-time price movements, helping you choose the strike prices that align with your predictions.
What is Nifty 50 Options?
Nifty 50 options are options contracts based on the Nifty 50 index, which tracks the performance of the top 50 companies listed on the NSE. These are popular in F&O trades because they provide exposure to the broader market rather than individual stocks.
