Market data
Daily price, traded quantity, delivery quantity, delivery percentage and trade-count fields are imported from public end-of-day files published through the National Stock Exchange of India archive. Delivery Volume stores validated fields in its own database so charts and tables can be served consistently.
The source archive is available at nsearchives.nseindia.com. Delivery Volume is an independent research interface and is not affiliated with, endorsed by or operated by NSE.
Nifty 500 membership
Company names, sectors and index membership are obtained from constituent files published by Nifty Indices. Membership changes over time, so the available universe reflects the most recently imported constituent file rather than a permanent historical membership list.
Update timing
Data is delayed and intended to update after the trading session. It is not a live exchange feed. The date shown on each page is the relevant freshness indicator; do not assume that the current calendar date is already available.
Corrections and availability
Source publishers may revise or replace files. Network problems, file-format changes or exchange holidays can interrupt an import. Delivery Volume validates required columns and numeric ranges, but it cannot guarantee that every upstream value is complete or free from error.
