MTF Data, API and Status

Endpoints

Two things that will bite you

Conventions

• All money is in INR crore (1 crore = 10,000,000).
• Dates are ISO-8601, YYYY-MM-DD.
• ISIN is the identity key, not the ticker — tickers get renamed and reused.
• src marks the funding exchange: N, B or N+B.
• BSE figures in this dataset begin on 03 Jul 2017; combined figures before that date are NSE-only. The exception is 11 days in 2017, 2020 for which no BSE file was published or recovered; on those days the combined book is NSE-only. The bse field is null for them in history/archive/index.json.

Data status

How current each feed behind the site is.

Daily checks

Every evening the newest day is checked: each exchange’s book against yesterday’s plus fresh funding minus liquidations, unusual moves, a missing BSE file, a change in archive depth, a stock that changed symbol or vanished, and feeds that stopped.

1 finding(s) on 23 Oct 2026.

• 23 Oct 2026Note: NSE: the exchange's file opens 2026-10-23 at Rs 146,439 Cr, not 2026-10-22's close of Rs 146,503 Cr (-64 Cr). The file itself adds up (opening + fresh - liquidations = Rs 143,773 Cr), so this is the exchange adjusting its opening (e.g. a security leaving MTF, or a revision), not a misread.
• 15 Oct 2026Note: BSE: the exchange's file opens 2026-10-15 at Rs 7,542 Cr, not 2026-10-14's close of Rs 7,488 Cr (+54 Cr). The file itself adds up (opening + fresh - liquidations = Rs 7,588 Cr), so this is the exchange adjusting its opening (e.g. a security leaving MTF, or a revision), not a misread.
• 14 Oct 2026Needs a look: BSE: book Rs 7,488 Cr, but 2026-10-13's Rs 7,563 Cr + fresh Rs 168 Cr - liquidations Rs 193 Cr = Rs 7,538 Cr (-50 Cr apart; usually within Rs 0 Cr). A day may be missing or a file misread.

Known gaps

• Headline figures start on 01 Aug 2017 SEBI's revised MTF disclosures began in late June 2017 and took weeks to fill as brokers moved onto them, so the book reads Rs 100-110 Cr in Jun-Jul 2017 against about Rs 1,900 Cr by the end of August -- a jump that never happened. The days from 28 Jun 2017 are kept in the archive, the date pages and the datasets; charts, tables and reviews start on 01 Aug 2017.
• 1 trading day(s) without a BSE figure The combined book is NSE-only on 11 Feb 2020. BSE published no usable file.
• Archive depth changed on 11 Nov 2025 Before it, the daily archive keeps the 500 largest positions; from it, 1,000. Sector figures use a fixed top-500 basis throughout, so the change never reads as a flow.
• 37 trading days missing from the archive NSE traded on these days but the archive has no MTF figure for them, so daily changes across them span two sessions and a month that ends on one shows its previous day: 2019: 18 Jan, 20 Mar, 04 Jun, 03 Oct, 11 Oct; 2020: 19 Mar, 21 May, 31 Jul, 11 Aug, 29 Oct, 08 Dec, 31 Dec; 2021: 14 Jan, 09 Feb, 24 Feb, 26 Feb, 04 Mar, 09 Mar, 22 Apr, 26 Apr, 28 May, 18 Jun, 02 Jul, 08 Jul, 20 Jul, 05 Aug, 25 Oct, 22 Nov, 09 Dec, 14 Dec; 2022: 17 Feb, 16 Mar, 28 Mar, 31 Mar, 13 Apr, 28 Apr, 06 May. They are being restored from the exchanges' original files.
• Per-stock market cap from 01 Feb 2024 Free float, size buckets, sector tilt and each stock's share of float need every company's market cap, which NSE publishes from then. The market-wide total and NIFTY 50 cover every trading day from 03 Jul 2017, from NSE's daily Market Activity report.

• 17 Oct 2026 Headline series starts on 01 Aug 2017. SEBI's revised MTF disclosures began in late June 2017 and took weeks to fill as brokers moved onto them: the book reads Rs 111 Cr on 30 Jun 2017 and Rs 103 Cr on 31 Jul, then Rs 1,942 Cr by 31 Aug -- a jump that never happened. Charts, the month-end and year tables, Insights reviews (from Sep 2017) and the 'tracking since' date now start on 01 Aug 2017. The earlier days remain in the archive, the date pages and the datasets.
• 10 Oct 2026 Sector figures measured over the top 1,000 stocks. Current sector books, shares and scrip counts had been cut at the 500 largest positions -- the depth the archive held before 11 Nov 2025 -- leaving about 18% of the book outside any sector. They now use the 1,000 the archive holds, with about 5% outside. Each change compares two days over the depth both hold (1D/1W/1M at 1,000; 1Y at 500), and long sector histories stay on a 500 basis so they remain like-for-like back to 2021.
• 07 Oct 2026 BSE restored on 13 trading days of 2025. BSE's files for 13-27 Mar, 2-3 Apr, 15 Jul and 30 Sep 2025 came in an older layout without ISINs, so those days had been NSE-only. They were rebuilt from BSE's own files: the combined book on each rose by Rs 3,020-4,588 Cr, and the false day-on-day drops beside them are gone.
• 30 Sep 2026 Monday data no longer held back by the weekend. BSE began answering 403 for files that do not exist; weekend dates read as unresolved and held the next trading day's data. Dates NSE shows were not trading days are now resolved.
• 28 Sep 2026 10- and 30-day movers include new entrants. A stock that entered the book during the window was left out; it now counts from zero, as the 1-day list does (NSE Ltd, listed 24 Sep 2026).
• 27 Sep 2026 Trends peak uses exact daily figures. A reconstructed peak sat Rs 8 Cr above the latest book on the same day; the peak now reads the exact daily archive.
• 26 Sep 2026 NSE Ltd's symbol corrected to NSE. BSE-only stocks were named from a 16-character company-name stub (NATIONALSTOCKEXC); they now use BSE's own ticker. The old page redirects.
• 25 Sep 2026 Market-cap total excludes NSE's summary row. The summary row was counted as a company, doubling the market-wide total. Market-wide ratios now show only on days the total agrees with NSE's published figure.
• 24 Sep 2026 Stock-page change windows on exact dates. 30-day, 3-month and 1-year changes had used month-end points; they now use the same exact dates as the Screener.
• 22 Sep 2026 One denominator for share of book. Sector shares had been measured against the top-500 sum; every share of book is now of the whole book, with the remainder shown.
• 22 Sep 2026 Month-end figures re-derived. Out-of-order backfills had left 9 of 24 month-end points on mid-month days; each month-end is now the last trading day of the month.
• 22 Sep 2026 Archive depth restored for 11-21 Sep 2026. The daily archive briefly kept 500 positions instead of 1,000, which read as a false fall of about Rs 20,700 Cr in sector totals. The days were re-fetched.
