About us

Last updated 29 September 2026

IndexOI is an online service for traders in Indian index and stock options. It shows the NSE option chain the way a trader reads it during the session: which side is writing, where the heaviest open interest sits, where support and resistance are forming, and the reversal level on each strike.

What we offer

• Option-chain sheets for NIFTY and BANK NIFTY, including the full chain view
• The same option-chain view for the F&O stocks
• Market-structure and straddle views, and replay of past NIFTY sessions for study
• Guides and videos on reading open interest

The sheets are a data and analysis tool. We do not give buy or sell calls, tips or advice; every trading decision is the subscriber's own. See our Disclaimer.

• Silver — 6 Months, ₹8,000
• Gold — 1 Year, ₹10,000
