B3 Markets

The exchange side of the record: every session print on B3's public COTAHIST tape since 2019 — cash equities, BDRs, units, listed fund quotas and the option boards. This is what actually traded, at what price and in what volume.

Quotes are unadjusted, straight from COTAHIST: a price series across a corporate action is discontinuous by construction, and papers with fator_cotacao ≠ 1 quote per lot rather than per share. Volume in R$ is comparable across papers; raw close prices are not always.

Unlike CVM filings, session data has no publication lag to heal — a series that stops means the ingest stopped, not the market (Pipeline Ops).

Monthly Traded Volume

Standard lot (tpmerc 010) against the odd-lot boards (020/021). The odd-lot band is small in R$ but is where retail order flow prints; a month with a blank band is a month with no tape ingested, not a month with no trading.

Volume by Instrument Type

The cash tape split by what the paper is — classified from B3's own CODBDI/ESPECI/ISIN codes, never from ticker shape. fund_quota is listed fund quotas, split into ETF and FII below.

right is a subscription right (ESPECI DIR) and bonus a bonus right (BNS) — claims on a security, not the security. index is an index line such as IBOV11, which despite its ticker is neither an ETF nor a tradable fund. All three used to sit inside cash_security, which is now the genuine residual: whatever ESPECI B3 prints that none of the named types covers.

Inside the fund_quota band: ETF versus FII exchange volume. A quota row whose board carries no family signal counts in the band above but in neither line here — the gap is real, not zero.

Most Traded — Last 90 Days of Tape

Top 15 tickers by standard-lot volume over the last 90 calendar days the tape covers (relative to the tape's own last session, not to today). Last Close is the raw unadjusted print.

Options Activity

Premium traded on the call (070) and put (080) boards — price × quantity of the option itself, not notional exercised; exercises print on separate boards and are excluded. Series count is distinct option tickers that printed at least once in the month.

IBOV Theoretical Portfolio

The 15 largest weights in B3's published IBOV theoretical portfolio on the latest date held (b3_index_portfolio, B3 BDI). History starts 2026-09-16: B3 publishes no archive, so this is a snapshot, not a series.
