What is Put 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).

This section allows users to select the expiry date for which they want to view the data. Options typically have multiple expiry dates, and selecting one updates the displayed data accordingly.

PCR Data Overview

1Put OI (Put Open Interest)

Put OI shows the total number of active Put option contracts for the selected symbol.

2Call OI (Call Open Interest)

Call OI shows the total number of active Call option contracts for the selected symbol.

3PCR (Put-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).

What PCR Values Mean?

4OI Strength %

OI Strength % indicates which side is stronger — Put OI or Call OI — in percentage terms.

It compares the difference between Put OI and Call OI against their total absolute open interest.

OI Change Analysis

5Put OI Chg (Put Open Interest Change)

Put OI Chg shows how much the Put Open Interest has changed compared to the previous period.

6Call OI Chg (Call Open Interest Change)

Call OI Chg shows the change in Call Open Interest compared to the previous period.

7COI PCR (Change in OI Put–Call Ratio)

COI PCR compares the change in Put OI with the change in Call OI.

It shows which side is seeing stronger fresh activity during the current period.

• COI PCR > 1 → Put OI change is stronger
• COI PCR < 1 → Call OI change is stronger

Meaning:
A low COI PCR indicates stronger call-side activity, often hinting at bearish pressure.

8COI Strength %

COI Strength % measures the balance between Put and Call activity based on Open Interest changes.

It tells you whether traders are adding more Put positions or Call positions during the current period.

This helps identify which side (bulls or bears) is more active in building fresh positions.

Interval

Interval determines how often the market data is refreshed on the chart. A shorter interval shows quick price and OI changes, while a longer interval smooths out market noise. Choosing the right interval helps you align the chart with your analysis timeframe.

Chart

PCR (Put–Call Ratio) – Intraday Chart

This chart shows the intraday relationship between the Put–Call Ratio (PCR) and the stock's market price (LTP). It helps in understanding sentiment changes during the trading session.

1How to Read This Chart

The X-axis (horizontal axis) represents time, showing intraday intervals from market open to close.

The Left Y-axis represents the Put–Call Ratio (PCR), while the Right Y-axis represents the stock's price (LTP).

To read the chart, observe how PCR and price move together or diverge over time to identify changes in market sentiment.

2What Each Line Shows

Blue Line – Put–Call Ratio (PCR)

The blue line shows the Put–Call Ratio at each time interval.

• Rising PCR → Increasing put activity (defensive or bullish bias)
• Falling PCR → Increasing call activity (bearish bias)

Extreme PCR values may indicate overbought or oversold conditions.

Grey Dotted Line – Stock LTP

The grey dotted line represents the actual market price of the stock or index.

• Shows real-time price movement
• Helps confirm whether PCR movement aligns with price action

How to Use This Chart

• If PCR rises while price is stable → Possible underlying support
• If PCR falls while price rises → Rally may be weak or unstable
• Best used with trend and volume confirmation

Note: PCR should be used as a sentiment indicator, not as a standalone buy or sell signal.

Put–Call Ratio Table – Column Guide

1Symbol

• This column shows the index symbol (such as BANKEX, BANKNIFTY, FINNIFTY)
• You can use the search box to quickly find a symbol. Clicking on a symbol opens its detailed PCR analysis

2Expiry

• This column displays the option expiry date for the selected index
• All Put–Call Ratio values in the row are calculated based on this specific expiry

3Symbol LTP

• Symbol LTP shows the current market price (Last Traded Price) of the index
• The arrow and percentage indicate how much the price has moved compared to the previous session
• 🔴 Down arrow → Price has fallen
• 🟢 Up arrow → Price has risen

Tip: Comparing Symbol LTP with PCR values helps in understanding whether market sentiment supports the current price move.

OI PCR (Open Interest Put–Call Ratio)

OI PCR helps you understand the balance between Put and Call positions based on total Open Interest.

aPut (Put OI)

• This column shows the total Put Open Interest for the selected symbol and expiry
• Higher values indicate stronger participation on the put side, often linked to support or hedging activity

bCall (Call OI)

• This column shows the total Call Open Interest for the selected symbol and expiry
• Higher Call OI usually indicates resistance levels or strong call writing activity

cRatio (OI PCR)

• This is the Put–Call Ratio calculated using total Open Interest
• It shows whether Put OI or Call OI is dominant

dOI Str (OI Strength %)

• OI Strength % converts the Put vs Call OI difference into a percentage value
• It clearly shows which side is stronger and by how much
• Positive value → Put side dominant
• Negative value → Call side dominant

Tip: Use OI PCR and OI Strength together to identify strong support or resistance zones.

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

COI PCR focuses on fresh activity by comparing the change in Put OI and change in Call OI during the selected interval.

aPut (Put OI Change)

• This column shows the change in Put Open Interest for the selected symbol and expiry
• A positive value means new put positions were added; a negative value means put positions were unwound

bCall (Call OI Change)

• This column shows the change in Call Open Interest during the same period
• Higher values indicate stronger fresh call-side activity, often linked to resistance or call writing

cRatio (COI PCR)

• This is the Put–Call Ratio calculated using OI changes instead of total OI
• It highlights short-term sentiment rather than long-term positioning

dCOI Str (COI Strength %)

• COI Strength % converts the difference between Put and Call OI changes into a percentage value
• Positive value → Put-side change dominant (bullish bias)
• Negative value → Call-side change dominant (bearish bias)

Tip: COI PCR is best used for intraday or short-term analysis, while OI PCR reflects broader positioning.
