In the dynamic world of stock trading, keen observers often come across the term “OI spurts.” Open Interest (OI) spurts refer to significant, sudden increases in Open Interest in the options market. 

To grasp the implications of this phenomenon, one must first understand the concept of Open Interest.

Decoding the Color Codes

  • Symbol Colors:

    • No color: Represents indices like Nifty or Bank Nifty.
    • Specific colors: Denote stocks such as Reliance, Asian Paint, and others outside the Nifty/Bank Nifty index category.
  • Type Colors:

    • No color: Represents futures.
    • Distinct color: Indicates options.
  • Change in %:

    • The intensity of the color deepens with the increasing percentage. This helps in swift visual interpretation.

Understanding Basic OI Concepts

Before delving deep, it’s essential to grasp some foundational concepts:

  • Open Interest Increase: The primary focus is on the rise in open interest. An increase in both OI and price suggests a ‘Long Buildup’. Conversely, if OI increases but the price drops, it’s termed as a ‘Short Buildup’.

  • Open Interest Decrease: If OI is on the decline, it’s pivotal to observe the price. An OI decrease with a price rise denotes ‘Long Covering’, while a drop in both is labeled ‘Short Covering’.

The Theta Factor

Theta, representing the rate of decline in the value of an option due to the passage of time, becomes especially pronounced on the day of expiry. In the Indian context, options expire on Thursdays. For weekly options like Nifty futures, which are devoid of the Theta concept, traders can simply go long or short based on the sheet’s indications.

Implementing the OI Spikes Tool

  1. Strategizing with the Top Five:

    • Buy positions from the top five in the ‘Long Buildup’ section.
    • Sell positions from the top five in the ‘Short Buildup’ section.
    • If any name disappears from the top five, close that particular position.
  2. Real-time Observations:

    • The tool updates every 10 minutes, offering a slower, more deliberate pace compared to the swift fluctuations of stock prices.
    • Morning data can offer invaluable insights. For instance, if all entries hit zero, it implies significant selling activity.
  3. Inferences & Predictions:

    • The tool can provide cues even when the market moves sideways. A substantial buildup in put options might suggest potential bullish breakouts, even if the price action remains ambiguous.
  4. Following the Big Players:

    • It’s often beneficial to track the moves of significant market players. If, for instance, there’s a surge in bullish sentiment for the upcoming week’s options, it might be wise to align trades accordingly.

The Open Interest Spikes tool, with its color-coded cues and real-time updates, offers traders a competitive edge. While it’s a potent tool, always remember to corroborate its insights with other analytical tools and market research. If you’re leveraging this tool, I’d love to hear about your experiences and insights.
