Historical Data

4Historical Date Selection

Allows users to navigate to a specific past date to view historical Strike Flow data. By selecting a date from the calendar, all charts and table data update to reflect the market activity on that day, making it useful for backtesting and trend analysis.

ATM Range

6ATM Range Selection

Allows users to select a predefined range of strike prices around the At-The-Money (ATM) level. Instead of manually setting start and end strikes, choosing an ATM range automatically centers the analysis around the current market price, making it quicker to focus on the most relevant strikes.

Time & Price Data

1Time

This column shows the exact time at which the market data was recorded.

In simple words, it tells when the Strike Flow (combined analysis) values were captured during the trading day, helping users track changes over different time intervals.

2Symbol LTP (Last Traded Price)

LTP stands for Last Traded Price of the selected symbol (such as NIFTY 50).

It shows the latest price at which the symbol was traded at that time. A green arrow indicates a price increase, while a red arrow indicates a price decrease compared to the previous interval.

OI Data (Unwinding)

3PE Unwinding

This column shows how many Put Option (PE) positions are being closed or reduced. It tells us how much traders are exiting put positions.

How to understand the value:

• Values are shown in negative numbers because positions are being closed
• A larger negative value indicates more put positions are being exited
• Higher PE unwinding suggests traders are reducing bearish bets, indicating a shift in market sentiment

4CE Unwinding

This column shows how many Call Option (CE) positions are being closed or reduced. It tells us how much traders are exiting call positions.

How to understand the value:

• Values are shown in negative numbers because positions are being closed
• A larger negative value indicates more call positions are being exited
• Higher CE unwinding suggests traders are reducing bullish bets, indicating a shift in market sentiment

5Unwinding Strength (Unwinding Str)

Unwinding Strength shows the relative strength between Call unwinding and Put unwinding. It helps identify whether bullish or bearish positions are being exited more aggressively.

Formula

How to read the result

• ≥ +60% → Bullish (Call unwinding is stronger)
• -60% to +60% → Neutral (Both sides are balanced)
• ≤ -60% → Bearish (Put unwinding is stronger)

Example

• CE Unwinding = -15,00,000
• PE Unwinding = -5,00,000

Unwinding Str % = (-15,00,000 − (-5,00,000)) / (15,00,000 + 5,00,000) × 100
Unwinding Str % = (-10,00,000 / 20,00,000) × 100
Unwinding Str % = -50%

Result: Unwinding Str % = -50%, which indicates Neutral sentiment with slightly stronger put-side unwinding.

OI Change (Buildup)

6PE Buildup

This column shows how many Put Option (PE) positions are being newly added. It tells us how much traders are creating new put positions.

How to understand the value:

• Values are shown in positive numbers
• A larger value indicates more put positions are being added

7CE Buildup

This column shows how many Call Option (CE) positions are being newly added. It tells us how much traders are creating new call positions.

How to understand the value:

• Values are shown in positive numbers
• A larger value indicates more call positions are being added

8Buildup Strength (Buildup Str)

Buildup Strength shows the relative strength between Put buildup and Call buildup. It helps identify whether the market is more bullish, bearish, or neutral.

Formula

How to read the result

• ≥ +60% → Bullish (Put buildup is much stronger)
• -60% to +60% → Neutral (Both sides are balanced)
• ≤ -60% → Bearish (Call buildup is much stronger)

Example

• PE Buildup = 20,00,000
• CE Buildup = 10,00,000

Buildup Str % = (20,00,000 − 10,00,000) / (20,00,000 + 10,00,000) × 100
Buildup Str % = (10,00,000 / 30,00,000) × 100
Buildup Str % = 33.33%

Result: Buildup Str % = 33.33%, which indicates Neutral sentiment (not above +60% threshold).

PCR & Max Pain Analysis

15Put Call Ratio (PCR)

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?

16COI PCR (Change in Open Interest Put–Call Ratio)

It shows which side added more fresh positions today — the put seller or the call seller.

COI PCR = Change in Put OI ÷ Change in Call OI

• If COI PCR is above 1:
  • More put OI was added than call OI.
  • Put sellers are stronger → the market has a bullish bias.
• If COI PCR is below 1:
  • More call OI was added than put OI.
  • Call sellers are stronger → the market has a bearish bias.

Example 1

• Put OI added today: 30,000
• Call OI added today: 10,000
• COI PCR = 30,000 ÷ 10,000 = 3
• This means put sellers are much more active, so the market has a bullish bias

Example 2

• Put OI added today: 15,000
• Call OI added today: 30,000
• COI PCR = 15,000 ÷ 30,000 = 0.5
• This means call sellers are more active, so the market has a bearish bias

17Max Pain

Max pain (also called "maximum pain price") is the strike price where option buyers, in total, would lose the most money at expiry and option sellers would lose the least amount of money.

At this price, the maximum number of call and put options expire worthless or with very little value, so most buyers lose their premiums while sellers keep most of what they collected.

Many traders believe that, as expiry comes closer, the underlying price sometimes moves toward this max‑pain strike, because big option sellers try to hedge or manage their risk around that level. Max pain is not a guarantee or a magic target, just one way to see how positions are stacked in the option chain.
