FNO Trader - A Free Tool to Track Options Greeks, Chain, Open Interest, Straddle & Orderflow

Updated: Dec 13, 2022

Options trading strategies are numerous and can be quite complex. In general, an options trading strategy involves the simultaneous purchase and sale of options contracts with different strike prices and/or expiration dates.


The purpose of an options trading strategy is to generate profits by correctly predicting the future direction of the underlying asset's price.


There are two main types of options trading strategies: directional and non-directional.


Directional options trading strategies bet on the future direction of the underlying asset's price. In contrast, non-directional strategies do not make any assumptions about the future direction of the price.

The most popular directional options trading strategy is buying call options or put options. Recently many options traders also started selling options even as a directional strategy.


The most popular non-directional options trading strategy is buying a straddle.

A straddle involves buying both a call option and a put option with the same strike price and expiration date.


The advantage of a straddle is that it doesn't matter which direction the underlying asset's price moves; as long as there is enough movement in either direction, the straddle will generate a profit.


There are endless variations of options trading strategies, and new ones are constantly created. The important thing is to find a strategy that fits your personality and risk tolerance.

What Are The Parameters Which Have an Impact on Options Trading?

Next, we will discuss the different parameters which affect options trading. These include:


  • The underlying asset: This is the security on which the option is based. It can be a stock, commodity, currency, or index. The price of the option is directly linked to the price of the underlying asset.

  • The strike price: This is the price at which the holder of the option can buy (in the case of a call option) or sell (in the case of a put option) the underlying asset.

  • The expiration date: This is the date on which the option expires and becomes worthless if it has not been exercised.

  • The premium: This is the price that the buyer of the option pays to the seller for the right to buy or sell the underlying asset at the strike price.

  • The open interest: This is the total number of options contracts that have been traded but not yet exercised.

  • The volatility: This is a measure of how much the price of the underlying asset is expected to move over the life of the option. A higher volatility means higher prices and greater risk.


Each of these parameters will affect the price of the option and, therefore, must be considered when trading options.

Options Chain

Options chain is a crucial tool for options traders that gives them a bird's eye view of the market and helps them make informed trading decisions.


It shows the prices of all the different options that are available for a particular underlying asset and also lists all the important information about those options, such as strike price, expiration date, etc. This allows traders to see what the market is doing and determine which options are currently in or out of the money.


Options chain is an important tool for options traders. It should be used in conjunction with other tools, such as technical analysis, to make informed trading decisions.


FNO Trader provides complete information about the options chain.

Options Chain Charts

Options chain is also useful for analyzing potential trades as well.


For example, if you are considering buying a call option, you can use the options chain charts to find out how much it would cost to buy the option, as well as the open interest (OI) and volume.


This information can help you decide whether or not the trade is worth taking.



FNO Trader provides complete information about the options chain charts.


Besides, it also provides the charts for both CE and PE for different strike prices of the options contracts.



Options Action

When it comes to options, the four main types of action are price, volume, open interest (OI), and OI change. Here's a brief explanation of each:

Price: This is the most straightforward type of options action and simply refers to the current market price of the underlying security.

Volume: This measures the number of option contracts that have been traded in a particular time period. It can be helpful in assessing market activity and sentiment.


Open Interest represents the total number of outstanding option contracts for given security. It can give you an idea of how liquid the options market is for a particular stock.


OI Change: This tracks the net change in open interest over a given time period. An increase in OI can be indicative of increasing demand for the options, while a decrease can signal waning interest.

Multi-Strike Open Interest (OI)

Open interest is the number of contracts that are held by traders and not yet offset by an opposite transaction. An increase in open interest indicates that new traders are entering the market and are bullish on the underlying asset, while a decrease in open interest means that traders are exiting the market or becoming less bullish.


Open interest (OI) can be used in options trading to gauge the market activity level and identify potential support and resistance levels. When open interest is high, it means that there are more traders interested in buying or selling the underlying asset.


This usually leads to more price volatility as there are more participants trying to push prices in their desired direction. When open interest is low, it typically means that there is less trading activity, and prices are less likely to move dramatically in either direction.


Open interest can also be used to confirm price movements. For instance, if the price of a stock starts to rise and open interest also increases, this is generally considered to be a bullish signal as it shows that new traders are entering the market and buying the asset.


Conversely, if the price of a stock falls while open interest declines, this is typically seen as a bearish signal as it indicates that traders are exiting the market or becoming less bullish on the asset.


So analyzing OI at multiple strike prices combines the overall action and gives an accurate indication of future movements.
