Data sources

MTF book

NSE CM — Margin Trading Disclosure daily Excel + BSE Margin Trading daily Excel (MarginTrading_*.xls / .csv). One row per stock per day with the outstanding amount financed (total value of shares held under MTF), fresh exposure, and exposure liquidated. Available since 22 June 2017.

Stock universe

NSE EQUITY_L.csv + BSE List of Scrips (ListofScripData). Resolves every symbol/scrip-code seen in the MTF files to a canonical name and ISIN.

F&O membership

NSE F&O bhavcopy (BhavCopy_NSE_FO_*). Point-in-time per day — an F&O stock added or removed mid-week shows the right membership for each historical bar.

ETF list

NSE eq_etfseclist.csv. Used to bucket the per-day MTF book into F&O / non-F&O / ETF.

ISIN / EOD close

NSE & BSE cash bhavcopy (BhavCopy_*_CM_*, EQ_ISINCODE_*). Provides the daily EOD close shown alongside per-stock MTF charts and the ISIN used to canonicalise stock identity.

Market cap

NSE PR price report (PR<ddmmyy>.zip → mcap*.csv) + BSE List of Scrips. Used for leverage % (book / mcap) and the % of universe view in the screener.

Company logos

Self-hosted SVGs vendored from the indian-listed-company-logos repo, keyed by ISIN. Stocks without a vendored logo fall back to a coloured initials monogram.

Source archival & provenance. NSE and BSE purge old reports from their own sites over time, so every external source file this site depends on — the daily MTF reports, bhavcopies, index/ETF lists, and the broker/rating documents — is continuously mirrored to the Internet Archive. Broker figures carry a \u{1F5C4} link to the archived copy of their primary source, so each number stays independently verifiable even if the original is taken down.

Aggregation rules

• Fill-forward — NSE and BSE publish on slightly different schedules. The combined daily total fills each exchange forward with its last known value so a one-sided publication day doesn't fake-collapse the headline number.
• ISIN identity — stocks are matched by ISIN across NSE and BSE. A renamed symbol or a truncated BSE company name still resolves to the same security; dual-listed stocks (HDFCBANK, INFY, etc.) collapse into one row in the screener.
• Active securities — a stock counts as "active" if it has at least one non-zero MTF row in the trailing 14 days. The screener and concentration strips both use this filter.
• Concentration share — "top N share" is computed against the active-market total at the same date as the per-stock snapshot, not against an all-time aggregate. So a stock that exited the active universe doesn't inflate yesterday's top-10 share.

Free float & ownership

Two free-float figures appear on the site, computed differently on purpose:

• Current free-float market cap (the “MTF vs Free-Float Market Cap” panel) uses NSE’s Investable Weight Factor free float per stock — ffmc / totalMarketCap from NSE’s quote API — applied to a fresh total market cap. NSE’s IWF is stricter than a simple non-promoter float: it also excludes strategic and large-institutional / locked-in holdings (e.g. RBL Bank, which has no promoter, reads ~40% not ~98%). For the ~2,500 BSE-only names NSE doesn’t list, BSE’s MktCapFF is the fallback. This is the authoritative current number.
• Historical free float (the “MTF book vs free float” chart) is derived from demat holdings, because no source publishes a back-dated free-float-market-cap series. We sum the monthly equity demat value by investor category from both depositories' BO Aggregate (CDSL + NSDL), and take free float = total − promoter/strategic, using the Corporate / Body-Corporate buckets as the promoter proxy. The result tracks India's documented promoter-holding decline (~49% in 2016 to ~45% now). Its level is anchored to the current NSE investable free-float figure so the chart's latest point matches the panel headline exactly; the demat series supplies the historical shape.

Honest caveats: depository data is by holder type, not promoter status, so the promoter proxy is an approximation (it lands at the known ~45–50%). CDSL's monthly archive is patchy for 2022–mid-2023, so CDSL's small (~14%) share is linearly interpolated between the nearest available months for that stretch (NSDL stays real); those months are flagged in the dataset. Months with an implausible jump are auto-excluded. The full per-category series is on the data page.

Refresh cadence

Data refreshes every Indian trading day after NSE and BSE publish their EOD disclosures — typically by 22:00 IST. The dashboard's "Last updated" stamp in the header reflects the freshest exchange. Holidays and exchange-specific outages mean the two sides can be one trading day out of sync. The demat-holdings free-float series is monthly (depositories publish month-end).

What is MTF?

Under SEBI’s Margin Trading Facility, a stockbroker lends you money to buy approved shares in the cash (delivery) segment. You put up an initial margin (in cash or pledged securities); the broker funds the balance and charges daily interest on it. The shares you buy are pledged to the broker as security until you repay. It is the cash-market cousin of a loan-against-shares — distinct from F&O, where leverage comes from futures/options margins, not a funded delivery position.

How it works

MTF book (amount financed)

What this site calls the MTF book is the exchange-reported amount financed — the total value of the shares held under the facility, i.e. your own margin and the broker’s funding combined, not just the broker’s loan. In the NSE/BSE daily files this works out to roughly the shares’ market value (amount financed ÷ shares ≈ the traded price): about ₹100 of funded stock, of which you might post ₹25 and the broker funds ₹75. The broker’s actual credit is therefore a fraction of the book. It rises when clients open fresh positions and falls when they repay or are squared off.

Pledge

Since 2020, MTF-funded shares must be pledged in your own demat account through the depository’s margin-pledge system (CDSL/NSDL) — the broker cannot move them to its own account. A haircut is applied to the pledged collateral’s value.

Daily interest

Interest accrues every day on the amount you’ve borrowed (the broker’s funding portion, not your own margin), typically in the ~9–24% p.a. range depending on the broker. This is the running cost of carrying a leveraged position — you can model it on the calculators.

Mark-to-market

Your position is marked to market daily. If prices fall and your margin drops below the required level, the broker issues a margin call; if you don’t top up, the position is squared off.

SEBI’s MTF framework

Eligible securities

Only shares the exchanges approve for MTF (broadly, more liquid “Group 1” stocks — those with derivatives or that meet liquidity/impact-cost criteria). The approved list is published and revised periodically by NSE and BSE.

Initial margin

You must fund a minimum initial margin per stock, set from the security’s risk (VaR + Extreme-Loss Margin), so more volatile stocks need more of your own money. The rest is what the broker funds.

Square-off & aging

If a margin shortfall isn’t met, the broker squares the position off. There are also limits on how long a funded position can be carried before it must be converted to delivery (fully paid) or closed.

Disclosure

NSE and BSE publish a daily MTF disclosure — per stock, the outstanding funded book, fresh exposure and exposure liquidated. That daily file is the backbone of this entire site (see the methodology).

The risks

MTF magnifies both gains and losses. A leveraged position that moves against you loses value faster than the cash you put in, and three things can compound the damage:

Margin calls & forced liquidation

A sharp drop can trigger a margin call; if unmet, the broker sells your shares — often at the worst possible time, and sometimes across many clients at once, adding to the fall.

Interest drag

You pay interest every day the position is open, whether the stock rises, falls, or goes nowhere. A flat stock held on margin still loses you money.

Concentration

When a large share of a single stock’s free float is funded on margin, an unwind can be hard to exit without moving the price — this site’s most-leveraged and crowding views track exactly that.

How to read this site

MTF book

The total value of shares held under MTF (the exchange’s amount financed) — client margin + broker funding combined, not just the loan — in ₹. “Combined” = NSE + BSE summed. This is the headline number.

Fresh / liquidated / net flow

New margin positions opened vs closed on a day (NSE-disclosed). Net flow can differ from the day-on-day book change — see the note on the daily pages.

% of free float

MTF book as a share of a stock’s freely-tradable market cap — how much of the tradeable float is margin-funded. Free float uses NSE’s investable-weight-factor basis.

Days to cover

MTF shares ÷ average daily volume — roughly how many days of normal trading it would take to unwind the book. Higher = more crowded.

Brokers

Per-broker MTF books, curated from credit-rating reports, annual reports and disclosures. See the brokers tab.

Every figure is downloadable on the data page and back-traceable on the methodology page.

FAQ

Is MTF the same as F&O leverage?

No. MTF is a funded delivery position in the cash market (you own the shares, pledged to the broker). F&O leverage comes from futures/options margins — no delivery, and different rules.

What happens on a margin shortfall?

The broker issues a margin call. If you don’t add funds/collateral in time, it squares off (sells) enough of the pledged shares to restore the margin.

Why do NSE and BSE numbers differ?

They are two separate exchanges with different broker mixes and eligible-security lists. A dual-listed stock’s combined book is the sum of both. NSE dominates the MTF book.

What is “free-float leverage”?

A stock’s MTF book divided by its free-float market cap — the share of its publicly-tradable value that is currently funded on margin. See /leveraged.

Does MTF cost anything if the stock doesn’t move?

Yes — daily interest accrues on the funded amount regardless of the stock’s direction. Leverage is not free.

Where does this data come from?

Directly from the daily MTF disclosure files NSE and BSE publish, plus official market-cap, ISIN and shareholding sources. No third-party estimates. Full lineage on the methodology page.

Can I use these numbers?

Yes, freely including commercially — please attribute “via mtf.trading, from NSE/BSE disclosures” and link back where you can. CSV/JSON on the data page.

/feed.xml

Atom feed of the daily combined NSE+BSE MTF book — one entry per trading day with the headline figure, day change, and flush / record-high notes, each linking to its dated snapshot. Subscribe in any reader, or poll it.

/date/<YYYY-MM-DD>.json

A full per-day snapshot — headline book, top-funded stocks, concentration, biggest movers, flow and breadth — for any trading day since 2017. The human page lives at /date/<DD-Mon-YYYY>; the data is the same path with a .json suffix and the ISO date.

/week/ · /month/ · /quarter/ · /year/ reports

Period MTF market reports — average book, sequential & year-on-year growth, cash + F&O ADTO, flow/breadth roll-ups, top-funded stocks and biggest movers, plus trend charts. Human pages at /week/<DD-Mon-YYYY> (Monday of the week), /month/<Mon-YYYY>, /quarter/<Qn-YYYY>, /year/<YYYY>; the same paths with a .json suffix (ISO key) return the data. Every week / month / quarter / year since June 2017.

URLs are append-only and stable — once a path exists it keeps working. All files are served no-cache with an ETag, so a conditional request is a cheap 304 when nothing changed. Add ?v= with any value to bust an edge cache.

How to cite & reuse

The data is derived entirely from public NSE and BSE disclosures and is free to use, including commercially. Please attribute — e.g. “MTF data via mtf.trading, from NSE/BSE disclosures.” — and, where possible, link back. The raw exchange files behind every figure are also documented on the methodology page and continuously mirrored to the Internet Archive (see status).
