Results

Intraday VWAP vs CMP · live Dhan feed

■ CMP ▬▬ VWAP · VWAP = Σ(typical price × volume) ÷ Σ volume, cumulative from 09:15. Tracks the index chosen in the selector. Snapshot auto-refreshes hourly on market days (9:30–15:30 IST) from real Dhan price + volume.

Educational tool only — not investment advice. OI-based metrics (Max Pain, PCR, HOI, S/R) reflect option-writer positioning and shift intraday; always confirm with live data and price action. India VIX is entered manually.
