Read end-of-day option-chain positioning and futures basis. This workspace refreshes after each NSE trading day and never places orders.
Expand a date to compare calls and puts around spot. Volume bars show each contract relative to the busiest visible strike.
Loading expirations…
Compare settlement, basis, open interest and daily positioning across available contracts.
Use several signals together when researching derivatives; no single option-chain metric predicts market direction.
Open interest shows outstanding contracts, OI change shows how that total moved during the session, and volume shows contracts traded. Compare calls and puts around the spot price to study participation and positioning.
The put-call ratio compares whole-chain put and call open interest. Max pain estimates the strike with the lowest aggregate option payout, while the largest put and call OI levels can help describe visible support and resistance zones.
Implied volatility reflects the volatility embedded in option prices. Delta, gamma, theta, vega and rho estimate model sensitivities. Futures basis compares a futures contract with its reported underlying price.
