What this site is

Broker Information tracks how many people actively trade the Indian stock market, and with which stockbroker. The headline series is the count of active clients (unique client codes, UCCs) per trading member on the National Stock Exchange — the figure the industry uses to rank brokers.

The source

Every number comes from one official file: NSE's Report 1C — “Report of Redressal of Complaints lodged by clients against Trading Members”, published on the NSE archives under miscellaneous/ArbitrationReports/isc_report1C_<FY>.xls. Alongside complaint statistics, the report carries each member's “UCC of active clients” and the exchange-wide “Total number of active clients for all the stock brokers of the exchange”.

Coverage

• Monthly from August 2020 to … — parsed from archived copies of the official file and cross-checked against the contemporaneous forum tables.
• Annual anchors back to FY 2013-14 — NSE still hosts each past fiscal year's file in its final state, giving one data point per year before 2020.
• Before FY 2013-14 the report tracked a different metric — registered client codes at the beginning of the year, not active clients — so those years are deliberately excluded rather than mixed in.
• A few months were never archived before NSE overwrote them (and NSE skipped publishing March 2026 entirely); for two early-2021 months NSE's own page served a correct total with a stale member table, so they carry the total only.

What “active client” means

The report itself does not define the term. The series behaves as a rolling measure of clients who have traded in the recent past (the industry convention reads it as “traded at least once in the trailing twelve months”): it is continuous across fiscal-year boundaries — for example March 2021 (1.89 crore) flows smoothly into June 2021 (2.11 crore) with no April reset.

How the data is processed

• Ranks are computed, not copied — the raw file is sorted by complaint count, so brokers are re-ranked here by active clients.
• Identity is name-based (the file has no member code). Corporate renames are hand-curated so a broker keeps one continuous history — e.g. RKSV Securities → Upstox Securities, NextBillion Technology → Groww Invest Tech, Angel Broking → Angel One. Cosmetic case/punctuation differences are normalized automatically; anything beyond that is never merged by a machine.
• Dating: recent files embed their as-of date; older snapshots are dated by the archive link curated for that month, by exact figure-matching against the forum tables, or by capture-time heuristics — the basis is recorded per source in the open dataset.
• Totals: the headline uses the exchange-wide stated total. The member table lists only reporting members, so the sum of listed brokers can sit slightly below the stated total.

Update cadence

An automated job checks NSE's current fiscal-year file twice a week. When a new month appears it is ingested, saved to the Wayback Machine for permanence, validated, and published here — typically within a few days of NSE's first-week update.

Open dataset

The raw archived files, the parsed per-month JSON, and a provenance manifest (URL, archive link, SHA-256, dating basis for every file) are maintained in a public repository: github.com/prayagverma/activetraders. Corrections are welcome.
