See Where the Big Money Is Positioned — OI Charts Reveal Support, Resistance & Max Pain
OI Charts visualises open interest data across all strikes for Nifty, BankNifty, FinNifty, and other indices in a color-coded bar chart — green bars for call OI, red bars for put OI, one pair per strike. Instantly identify where institutional call sellers are defending resistance, where put writers are supporting price, and which strike is the max pain magnet heading into expiry. Switch between weekly and monthly expiries with one click. Works for NSE, BSE, and commodity indices. The open interest view every options trader checks before picking a strike — built directly into the OptionX dashboard.

Frequently Asked Questions
Open Interest is the total number of outstanding options contracts at a given strike that have not been settled or closed. High OI at a strike means a large number of participants are holding positions there — creating potential support (high put OI) or resistance (high call OI). OI helps you understand where institutional money is positioned, which price levels are being defended, and where the market is likely to gravitate heading into expiry.
