Read the option chain in seconds, not minutes.
Peak open interest, Put-Call Ratio, Max Pain, support and resistance, and one clear read on how calls and puts are positioned right now — for Nifty, Bank Nifty, Sensex, Midcap Nifty and Fin Nifty.
The numbers that matter, without the clutter
No dashboards to configure. Open the app and the read is already on screen.
Peak OI, centred
The chain opens on the strike carrying the most open interest, with ten strikes either side. Switch to the full chain whenever you want.
PCR with a real scale
Put-Call Ratio on a meter marked at the 0.7 and 1.3 sentiment bands, so the number means something at a glance.
Max Pain
Where the chain is positioned to expire, recalculated on every refresh from the full strike ladder.
Support and resistance
Detected automatically from the strikes holding the most put and call open interest, and tagged inline on the chain.
Every row, fully loaded
Open interest, last price and change in OI on both legs without tapping. Tap a strike for the full CE and PE comparison.
Alerts and a home-screen widget
Heavy writing on a strike, a PCR flip, a Max Pain shift — checked every fifteen minutes during market hours, silent outside them.
Index Sentiment
Calls and puts each tell you something on their own. Read together, they tell you how the market is actually positioned. Index Sentiment takes the dominant call build-up and the dominant put build-up across the seven strikes around peak open interest, and gives you one verdict — with a confidence rating and a plain-English reason.
Call buyers and put writers both expect upside.
Sixteen build-up pairings, each with its own reading — from Strong Bullish through Sideways and Low Conviction to Strong Bearish.
Every strike, classified on both legs
Price and open interest move together in four ways. The app labels each leg so you can read a row without doing the arithmetic.
