Header Controls

1Index Tools Dropdown

Allows users to select the type of analysis they want to view, such as Call OI chg vs Put OI chg, Call OI vs Put OI, or Volume-based analysis. Once selected, the charts and data update accordingly.

2Symbol Selection Dropdown

Lets users choose the market index or symbol (e.g., NIFTY 50, BANK NIFTY, FINNIFTY). Selecting a different symbol updates the data to show Call OI chg vs Put OI chg specific to that index.

3Expiry Date Dropdown

Strike Price & Interval Controls

4Start Strike Price Dropdown

Allows users to select the starting strike price for the analysis range. The data and charts will begin calculating Call OI chg vs Put OI chg from this selected strike price.

5End Strike Price Dropdown

Used to select the ending strike price for the analysis. Together with the start strike, it defines the complete strike price range included in the analysis.

6Interval Selection Dropdown

Lets users choose the time interval (such as 1 min, 5 min, 15 min, or 30 min) for data calculation. A smaller interval shows more frequent changes, while a larger interval provides a smoother and broader market view.

Chart/Graph

Chart Explanation

• Green Line – CE OI Chg: Intraday change in Call Open Interest. When this line rises, it means new call positions are being added during the day.
• Red Line – PE OI Chg: Intraday change in Put Open Interest. When this line rises, it means new put positions are being added during the day.
• Grey Line – Stock LTP: Represents the NIFTY spot price movement throughout the session.

OI Change Summary (Left Bar Chart)

• CE OI Chg: ≈ 23.79 L
• PE OI Chg: ≈ 18.32 L

Conclusion: Since fresh Call OI addition is higher than Put OI addition, it indicates intraday bullish positioning by option writers in this price range.

Time & Price Data

1Time

The timestamp when the data was recorded. Each row represents data at different intervals during the trading day (15:30, 15:15, 15:00, 14:45, etc.).

2Spot LTP (Last Traded Price)

Nifty 50 last traded price at that time. The green/red tag below shows how much it changed from the previous interval and the percentage move.

Open Interest Change Analysis

3PE OI Chg (Put Option Open Interest Change)

Net change in put open interest in this strike range compared to the start of the day.

• Positive value: Puts are being added (fresh put positions).
• Negative value (as in this image): Puts are being unwound/closed.

Example (15:30):

PE OI Chg = 18,32,104 with a ↓ of –7,06,896 from the previous reading → total intraday put buildup is still 18.3L above the morning level, but 7.06L has been cut since the prior interval.

4CE OI Chg (Call Option Open Interest Change)

Net change in call open interest compared to the start of the day.

• Positive value: Calls being added.
• Negative value: Calls being unwound.

Example (15:30):

CE OI Chg = 23,78,918 with ↓ –9,48,685 → still large net call buildup on the day, but heavy profit-booking/unwinding into the close.

5Difference

Shows the net gap between Put Option Open Interest Chg (PE OI Chg) and Call Option Open Interest Chg (CE OI Chg) for the selected strike range.

Formula

• Negative value (like –5,46,814 at 15:30) means call change > put change, so intraday additions are more on the call side.
• Positive value would mean put change > call change.

This tells you which side is dominating fresh intraday positions.

Conclusion: A negative difference means the call side is stronger, indicating resistance in that zone.

PCR & Max Pain Analysis

6PCR

Put–Call Ratio (PCR) is a market sentiment indicator that compares how many put options are being traded (or are open) to how many call options are being traded (or are open) for the same index or stock. It tells you whether traders, as a group, are more focused on protection/downside (puts) or on upside (calls).

What PCR Values Mean?

7Intraday PCR

Measures the ratio of today's put option activity to today's call option activity within the trading day. Usually calculated using today's traded volume (or today's change in OI) of puts divided by today's traded volume (or change in OI) of calls for that day. It tells you what traders are doing right now during the session, not what they have built over many days.

Formula and Difference from Normal PCR

Normal PCR uses total PE OI ÷ total CE OI for that expiry and range.

Intraday PCR uses today's fresh build-up or volume in PE ÷ today's fresh build-up or volume in CE for the same period.

So:

If Intraday PCR is very high, it means that today more puts are being added or traded than calls, showing strong fear/bearish hedging intraday (often a contrarian bullish hint if extreme).

If Intraday PCR is very low, it means today traders are aggressively taking call positions compared to puts, showing intraday bullishness that can become over-optimistic at extremes.

8Max Pain

The strike price at which option buyers (calls + puts together) would lose the most money at expiry, and option sellers would gain the most.

• If max pain is below the current LTP, it is shown in red (price trading above the max‑pain level).
• If max pain is above the current LTP, it is shown in green (price trading below the max‑pain level).
