How to Identify the At-the-Money (ATM) Strike in the ORCA Trading App

Introduction

The At-the-Money (ATM) strike is one of the most important reference points in options trading. Since the ATM strike is closest to the prevailing Spot Price of the underlying stock or index, it is commonly used by traders to assess option activity, Open Interest (OI), and market sentiment before entering a position . During live market hours, manually identifying the ATM strike and switching between multiple analytical tools can take time. The ORCA Trading App by Enrich Money simplifies this process through its Option Analysis module. By bringing together the Option Chain, OI Analysis, OI Surge, OI Statistics, Options Chart, Trending OI, and PCR within a single interface, ORCA helps traders identify the ATM strike and continue analysing market activity without leaving the same workspace. Whether you're learning options trading or searching for the best trading app in India for beginners, ORCA offers an intuitive option analysis experience.

What Is an At-the-Money (ATM) Strike?

An At-the-Money (ATM) strike is the strike price that is closest to the current market price (Spot Price) of the underlying stock or index . Let's consider a stock with a Spot Price of Rs. 749.50 and the available strike prices are Rs. 740, Rs. 750, and Rs. 760, then Rs. 750 is considered the ATM strike because it is the nearest available strike price . As the Spot Price changes throughout the trading session, the ATM strike may also change. This is why traders generally monitor the live Spot Price while analysing option contracts.

Why Is the ATM Strike Important?

The ATM strike serves as an important reference point for analysing option contracts. After identifying it, traders often evaluate factors such as Open Interest, strike-wise activity, and price movement to better understand current market positioning.

Many traders also compare the ATM strike with nearby In-the-Money (ITM) and Out-of-the-Money (OTM) strikes to understand how option activity differs across strike prices.

Once the ATM strike has been identified, traders can continue analysing it using ORCA's built-in option analysis tools without leaving the Option Analysis module, making ORCA a practical stock investment app for traders analysing options.
