Bulk deals are a client trading over 0.5% of the equity in a session, aggregated across their trades; block deals are single negotiated trades in the exchange’s block window. Each is reported by the exchange it was crossed on, so NSE and BSE rows are separate trades rather than the same trade twice.
Current officeholders as filed with BSE. A person holding two offices is listed once per office.
Only about 210 stocks have listed futures and options. Contracts appear here for those, refreshed after each close.
No scheme among the 32 fund houses on record reported a position in National Oxygen Ltd. Portfolios are published monthly by each AMC; coverage is still partial.
