Chart/Graph
1Unwinding Graph
Unwinding Chart – Explanation
The Unwinding Chart shows how existing Call (CE) and Put (PE) option positions are reduced or closed during the trading day.
The X-axis represents time from market open (9:15 AM) to market close, while the Y-axis represents unwinding value in Lakhs (L), showing how much open interest is being removed.
The green line (CE Unwinding) indicates call option position exit, while the red line (PE Unwinding) indicates put option position exit. Values appear in the negative direction because positions are being closed.
A sharp downward move means heavy position exit. Higher CE unwinding suggests loss of bullish interest, while higher PE unwinding suggests loss of bearish interest.
In short: This chart helps identify where traders are booking profits or cutting positions, giving insight into weakening or reversing market sentiment.
2Buildup Graph
Buildup Chart – Explanation
The Buildup Chart shows how new Call (CE) and Put (PE) option positions are created throughout the trading day.
The X-axis represents time from market open (9:15 AM) to market close, while the Y-axis represents buildup value in Lakhs (L), indicating the amount of fresh open interest added.
The green line (CE Buildup) reflects call option position creation and is generally associated with bullish expectations. The red line (PE Buildup) reflects put option position creation, usually indicating bearish expectations or strong support levels.
A rising line means more new positions are being added. Higher PE buildup suggests market support, while higher CE buildup indicates bullish sentiment. If both rise together, the market may remain range-bound or volatile.
In short: This chart helps to understand market sentiment over time by tracking how aggressively call and put positions are built during the day.

Unwinding Data
3PE Unwinding
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
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
Buildup Data
6PE Buildup
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
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
Strength & Analysis
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:
Unwinding Str % = (CE Unwinding − PE Unwinding) / (|CE Unwinding| + |PE Unwinding|) × 100
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
Applying the formula:
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.
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:
Buildup Str % = (PE Buildup − CE Buildup)/(CE Buildup + PE Buildup) × 100
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
Applying the formula:
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 Bullish sentiment as it's above +60% threshold, meaning put buildup is notably stronger than call buildup.
15Put Call Ratio
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).
Formula:
Put–Call Ratio (PCR) = Total Put Open Interest ÷ Total Call Open Interest
Example:
- Total Put Open Interest = 24,00,000
- Total Call Open Interest = 20,00,000
Calculation:
PCR = 24,00,000 ÷ 20,00,000 = 1.20
What PCR Values Mean?
| PCR Range | Market View |
|---|---|
| > 1.2 | Bullish |
| 0.8 – 1.2 | Neutral |
| < 0.8 | Bearish |
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 seller are stronger → the market has a bullish bias. -
If COI PCR is below 1:
• More call OI was added than put OI.
• Call seller 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
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
17MaxPain
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. so max pain is not a guarantee or a magic target, just one way to see how positions are stacked in the option chain.
