Source Catalog and Access Boundaries¶
This page and Acquisition Status form the Source Transparency section. This page answers what a source is and how it may be used; Acquisition Status answers what connectors actually collected. They document provenance rather than listing the same works through another index. Use the Research Catalog to find works.
This page records public entry points, content types, and access boundaries. Read publication content on the original site. The canonical integration state is
the repository's config/sources.toml: enabled RSS/Atom feed entries and purpose-built
metadata connectors store only public metadata and original links, while disabled
catalog/manual entries are verified candidates,
not harvested sources. Technical reachability is not permission to copy or redistribute. A
purpose-built adapter and permission review are required when structure, terms, or point-in-time
semantics are unstable.
See Acquisition Status for connector status, record counts, and date ranges.
| Source | Public content type | Access and use boundary |
|---|---|---|
| Options Industry Council | Options foundations, terminology, and risk education | Use for foundational fact checking; link to the original rather than copying pages |
| Cboe Options Institute | Exchange options education and market-structure material | Distinguish education, contract specifications, and market commentary |
| Man Insights | Institutional research, market views, and education | Current terms prohibit unapproved public-use crawling, linking, storage, archiving, extraction, or database creation; do not connect the site and use only independent reusable DOI metadata |
| Two Sigma Insights | Research, engineering, and institutional articles | Register public entry points only; do not infer or record undisclosed methods |
| Oxford-Man Institute | Academic papers and institutional research | Resolve arXiv identifiers from the official selected page through the arXiv API and retain separate bounded Crossref-affiliation candidates; SSRN-only entries remain catalog-level, so this is not a complete institution history |
| OptionMetrics Research | Options-data research, blog posts, and related academic papers | The public feed is enabled; label data-vendor interests and classify academic output independently by DOI/status |
| AQR Research | Factor, allocation, risk-premia, and systematic research | Site terms prohibit copying or publishing website information without written consent, so the official catalog is not harvested. The quarterly archive contains only DOI bibliographic metadata from the top 100 Crossref affiliation candidates that pass full institution-name and finance-context checks; it is not a complete AQR website history |
| D. E. Shaw Library | Quantitative methods, markets, and institutional articles | Review the public Library only; do not infer undisclosed strategies or current positions from firm reputation |
| Jane Street Blog | Technology, markets, and trading-infrastructure articles | The public stream is mostly OCaml/engineering; filter finance manually and do not infer proprietary alpha |
| NYU Volatility and Risk Institute | Volatility, systemic-risk, and academic research | Use the institution page as context; separate model output from peer review and retain data as-of dates |
| Research Affiliates | Valuation, factors, smart beta, and allocation research | Label product-linked backtests, hypothetical results, and PIT/cost limitations |
| Citadel | Public asset-manager research context | Keep separate from Citadel Securities; there is no stable public alpha archive, so do not infer internal methods |
| Citadel Securities GMI | Market structure, positioning, flow, and short-term mechanics | Proprietary analytics/flow do not represent the whole market; label market-maker interests and validate externally |
| Citadel Securities Policy Positions | Long-running policy archive on options auctions, OCC fees, tick sizes, Rule 605, best execution, CAT, and related topics | Manual catalog of a market maker's policy positions; prefer the linked SEC, FINRA, OCC, or venue originals for rule facts |
| Risk.net Cutting Edge | Papers, podcasts, commentary, and features | Identify document type and access status per item; do not store restricted full text |
| Cboe Insights | Exchange research, rules, and education | Distinguish rule facts from commentary; do not copy page content |
| Moontower | Options, volatility, and portfolio research notes | Treat practitioner views as research leads; independently validate conclusions and backtests |
| HKEX RSS | Market communications, futures trading rules, and options-clearing rules | Store feed metadata and original links only; distinguish rule facts from exchange views |
| JPX RSS | Market news, trading halts, and site updates | JPX states that URLs, contents, and formats may change; confirm rules on the original page |
| DTCC RSS | Clearing, settlement, rule filings, and institutional research | Use public feeds for event and bibliographic discovery only; do not copy attachments or restricted material |
| IBKR Traders' Insight: Options | Options education, market commentary, and practitioner articles | Broker and contributor quality varies; review commercial interests and evidence per item |
| Federal Reserve FEDS | Finance and economics working papers | Use the official research-paper RSS; working papers are not peer review, and broad content remains subject to the core threshold |
| BMLL Resource Centre | Level 3 order-book research, white papers, and case studies | No verified public feed; manually distinguish empirical evidence, case studies, and data-product marketing |
| SIX Trading InfoSnacks | Price formation, auctions, stale quotes, fill likelihood, and liquidity research | Follow the article series or email manually; cross-check the exchange perspective against multi-venue data |
| Liquidnet Insights | APAC/EMEA liquidity, dark-market, and execution reports | Current terms restrict copying and redelivery, so a technically readable legacy RSS remains disabled; register public entry points only |
| MEMX Insights | Tick-size, access-fee, options, and market-reform commentary | Register manually and label the venue's policy position and conflicts explicitly |
| JPX Working Papers | Japanese market-structure, derivatives, and execution-cost working papers | Pair the official English and Japanese indexes at low frequency; store titles, original dates, identifiers, and official links only, never PDFs. Author views are not JPX opinions, and commercial collection requires permission |
| Cboe Options Institute Research | Options, 0DTE, volatility, and strategy papers | The archive mixes exchange, academic, sponsored, and practitioner material; classify publication status and conflicts per item |
| CME OpenMarkets | Futures, options, basis, delivery, and macro-market articles | The official page offers email subscription rather than a verified research feed; manually filter product education and promotion |
| SEC Market Structure Analytics | SEC staff research, MIDAS visualizations, and downloadable data | Primary for its published data and regulatory definitions; do not interpret regulatory analysis directly as tradable alpha |
| Virtu Thought Leadership | Monthly regional market-structure and quarterly cost reports | The page is current, but its public RSS contains one untitled 2020 item; follow manually and label market-maker/execution-provider interests |
| Nasdaq Market Makers | ETF, index, trading-mechanism, and data-driven market articles | Follow the feature page or email manually; do not substitute a noisy generic Nasdaq feed for targeted filtering |
| NYSE Data Insights | Auction, ETP, options, and transaction-cost archive | Current publication frequency trails peers; re-check mechanisms and rules against current NYSE documents |
| IEX Square Edge Research | Midpoint, dark/lit trading, closing liquidity, and routing | Still active; label IEX product and policy interests per item |
| BestEx Research | ATS, futures-cost, intraday-timing, and volume-forecasting research | Private samples and execution products create conflicts; independently replicate findings |
| Quantitative Brokers Research | Futures rolls, liquidity, execution, and TCA | Use as an execution-hypothesis source and label the service provider's commercial interest |
| CFM Thinking | Market impact, price formation, volatility, and systematic investing | CFM's site terms allow personal storage only and require express approval for inbound links, so public pages neither link to nor harvest the official archive; only reusable DOI bibliographic metadata from a bounded Crossref candidate query is stored, and it is not a complete CFM history |
| Tradeweb Insights | Rates, credit, ETFs, RFQ, and automated execution | Large mixed catalog; filter corporate and product news and label proprietary platform samples |
| MarketAxess Insights | Fixed-income liquidity, auctions, all-to-all, and automation | Register public entry points only and label the venue/product perspective |
| ICE Insights | Fixed income, energy, equities, indexes, and data analytics | ICE explicitly restricts copying and redistribution; retain links only and keep automation disabled |
| Eurex Research | European option liquidity, settlement, and order-book design | Check audience and use terms per document; some files at public URLs are marked for QIB readers only |
| FIA EPTA | European electronic-market-maker and market-structure policy papers | Treat as advocacy and verify rule facts with regulators and venues |
| FIA Principal Traders Group | US principal-trader white papers, annual reports, comment letters, and market-structure discussions | Register separately from FIA EPTA; treat as liquidity-provider advocacy and verify rule facts with SEC, CFTC, OCC, and venue originals |
| ORATS Blog | Skew, surfaces, earnings, and options-strategy research | Data/API/backtesting products create vendor conflicts; no stable feed is verified, and claims require independent validation |
| ORATS Video | Videos on options data, volatility, surfaces, backtesting, and product workflows | The official channel Atom feed is enabled for daily tracking. It exposes only 15 recent uploads, while the 140-item official video catalog lacks reliable publication dates; quarterly history therefore includes only acquired items with verified dates and makes no completeness claim. Vendor examples still require independent validation |
| Options Insight | Volatility surfaces, gamma, VIX, and options-structure commentary | Disclose commercial membership and trading interests; use as hypotheses, not validated evidence |
| QVR Advisors Research | VRP, hedging, convexity, and derivatives archive | Many documents use DocSend; register links only and do not infer current positions or operating status from historical papers |
| Options Industry Council Research | OIC/OCC education and commissioned research | Dates and document types are mixed; author views need not represent OIC, so classify and validate every study |
| Artemis Capital Research | Historical volatility, convexity, and portfolio research | The visible archive is older; retain dates and treat manager narratives and backtests as conflicted evidence |
| Ambrus Group | Volatility and convexity research leads | Some publicly reachable PDFs carry confidentiality/no-copy language; never ingest or redistribute them, and retain permitted landing metadata only |
| Alpha Exchange | Practitioner interviews on volatility, options, hedging, and markets | Its site-advertised RSS is enabled; interviews are leads, while guest incentives and research claims need separate verification |
| The Derivative by RCM Alternatives | Interviews on managed futures, volatility, options, hedge funds, and alternatives | The publisher's open podcast RSS is enabled to preserve dated history from 2020 onward and continue daily tracking; the recent-only YouTube Atom feed is not fetched in parallel, avoiding duplicates. The subject range is broad, so only records passing the relevance threshold enter the quarterly archive's automatically selected section, and guest or commercial claims require separate verification |
| Macro Hive Video | Macro, policy, systematic-investing, machine-learning, market-interview, and weekly videos | Numbered podcasts use the publisher RSS, preserving dated history from March 2020; the channel Atom tracks non-podcast videos only and excludes Ep. titles to prevent duplicates. YouTube exposes only 15 recent uploads, so non-podcast history remains partial. All records face the normal options/volatility threshold, and commercial research or guest claims require independent validation |
| Maven Securities Research | Volatility surfaces, alpha decay, systematic trading, market structure, and engineering articles | The official paginated RSS is enabled: all 25 currently visible records (May 2021–September 2023) enter the quarterly source archive and the main feed supports future daily discovery. The official Short-End Listed Option Language Explainer is also linked, but it has no independently verified feed publication date and is not assigned to an invented quarter. Careers, culture, and engineering posts still face relevance filtering; only metadata and original links are stored |
| Tower Research Capital | Liquidity, rates, market structure, and prediction-market articles | The general archive is useful, but current terms restrict robot/page scraping and automated monitoring; retain a manual catalog only, with no RSS or full-text ingestion |
| XTX Markets | Client insights and market-design, liquidity, and execution white papers, including Hosted Rooms | Principal liquidity-provider perspective; keep manual and validate policy and proprietary-sample claims with external evidence |
| DRW Insights | Occasional ETF, derivatives, and market-structure articles | Mixed with careers/culture content and needs manual filtering; do not infer undisclosed strategies |
| DRW ETF Flow Reports | Historical ETF flow reports from 2022–2023 | Low-frequency manual market-liquidity reference; validate flow interpretations with independent venue or fund data |
| Flow Traders | Insights, Market Regulation, ETF-liquidity, and market-structure material | Follow the topical sections manually and filter company announcements; label principal-trading interests and do not imply a comprehensive archive |
| GTS Market Structure Commentary | Sparse market-structure commentary, public testimony, and policy positions | The public stream is dominated by corporate material, so retain a low-frequency manual catalog rather than a daily feed |
| HKEX Group Insight | Stock options, liquidity, products, and market structure | Separate from enabled HKEX notice/rule feeds; distinguish research and exchange promotion per item |
| HKEX Derivatives Statistics | Volume, open interest, and derivatives statistics | A future adapter must preserve report dates, definitions, revisions, and product identifiers; use manually for validation meanwhile |
| SGX Market Updates | Asian equities and derivatives market updates | Manually separate statistical/mechanism facts from product promotion; no targeted feed is verified |
| TAIFEX | Futures/options prices, settlement, OI, specifications, and history | TAIFEX states there is no database API and restricts reproduction/distribution; use permitted manual downloads pending authorization |
| KRX Derivatives | KOSPI 200 and other derivatives specifications, rules, notices, and data | Dynamic pages need a dedicated adapter, with rule versions and effective times preserved |
| ASX Derivatives | Contracts, settlement mechanics, statistics, and insights | Preserve opening-price settlement rules and methodology versions in particular; no targeted feed is verified |
| B3 Market Reports | Derivatives, OI, reference, and methodology reports | Separate public reports from paid DATAWISE; future ingestion must retain dates, schemas, and revisions |
| NSE Derivatives Snapshot | Indian derivatives snapshot and analytical tools | Dynamic delivery, access controls, and terms preclude generic scraping; wait for a permitted stable interface |
| S&P DJI Consultations | Proposed index-methodology changes and results | Preserve announcement, reference, effective, implementation dates, and exact methodology versions; index licensing still applies |
| MSCI Index Announcements | Index changes, reviews, and methodology events | Requires point-in-time capture of affected indexes, document versions, and effective dates |
| FTSE Russell Consultations | Index and expiry-settlement methodology consultations/results | Preserve proposal, result, implementation, and rulebook dates; do not redistribute licensed index content |
| Nasdaq Index Research | Index, ETF, autocallable, and market research | Separate methodology facts from product analysis; independently validate investable-index and backtest claims |
| STOXX Rulebooks | Index rulebooks, methodology documents, and notices | Future ingestion must version documents instead of overwriting current rules and must respect index-data licensing |
| Solactive Announcements | Methodology changes, consultations, and corporate-action notices | Record point-in-time events by index, document, and effective date; provider analysis is not independent evidence |
| Morningstar Indexes Insights | Large index research and commentary archive | Filter product material, preserve methodology dates, and label the index-provider commercial perspective |
| Nikkei Indexes | Methodology, constituent, guidebook, and PAF notices | Nikkei restricts reproduction; retain links, event metadata, exact effective dates, and methodology versions only |
| Hang Seng Indexes | Factsheets, constituent changes, methodology, and review notices | Track dynamic/licensed documents manually pending a permitted point-in-time adapter |
| FINRA OTC Transparency | Delayed ATS and non-ATS reported data | Preserve publication lag, definitions, tiers, symbol changes, and revisions; it is not a real-time signal |
| CFTC Commitments of Traders | Weekly futures/options positioning and historical structured files | Align Tuesday positions to Friday releases, retain report type/revisions, and prevent look-ahead |
| OCC Market Data | Listed-options volume and open-interest reports | Retain as-of dates, class/exchange definitions, and corrections; use for state validation, not causal inference |
| OFR Working Papers | Financial-stability, markets, and data-method working papers | Works in progress whose author views need not represent OFR; verify later publication and reproducibility |
| Liberty Street Economics | New York Fed markets, liquidity, and economics blog | Its official RSS is enabled; broad content still passes the core score, and posts need not represent the New York Fed |
| New York Fed Economic Policy Review | Lower-frequency policy journal and market studies | Preserve issue/publication dates and distinguish staff analysis from policy statements |
| BIS Quarterly Review | Quarterly global banking/market analysis and chart data | Preserve release and data-vintage dates; signed articles may express author views only |

| ESMA Publications and Data | EU research, statistics, consultations, and market-structure material | Classify legal status and preserve consultation/effective dates; a call for evidence is not a settled rule |
| Bank of England Working Papers | Transaction-level derivatives and market-microstructure papers | Preliminary work may reflect authors only; check samples, data access, and later publication status |
| WFE Research | Exchange/CCP research, statistics, and reports | Represents member venues; cross-check mechanism claims with regulatory and venue-level data |
| FIA Market Structure | Futures-industry advocacy, commentary, news, and events | Classify each item; verify legal/rule claims with regulators, venues, and clearinghouses |
| ISDA SwapsInfo | Derivatives statistics and quarterly reviews | Treat definitions, coverage, and release lags as data; industry-association policy views are not independent evidence |
| SIFMA Market Metrics | Monthly equity, options, and capital-markets metrics | Preserve sources/release dates and label the industry perspective; use for descriptive validation only |
| Acadian Systematic Methods | Systematic investing, electronification, and quantitative methods | Label manager/product conflicts; independently test hypothetical results and proprietary samples |

| Alpha Architect Blog | Research summaries, replications, and practitioner commentary | Label asset-manager products and secondary summaries; verify against original studies and reproducible code |

| MSCI Research & Insights | Index, factor, risk, and market research | Keep separate from PIT announcements; never replace historical membership with current constituents, and label provider/product interests |

| JPX Futures & Options Reports | Official recurring derivatives reports and statistics | Preserve period, publication date, product definitions, revisions, and document versions; do not conflate with the JPX notice feed |

| ETF.com | ETF news, tools, education, and industry commentary | Event discovery only; distinguish reporting from sponsored/product content and verify against primary documents |
| ETF Stream | ETF industry news, analysis, and opinion | Secondary discovery source; label sponsored/provider material and verify index, flow, and mechanism facts |

Deliberate boundaries outside the current core¶
- Kaiko, Deribit Insights, Block Scholes, Amberdata, Glassnode, Coin Metrics, and Jump Crypto belong to digital-asset market structure. Their 24/7, perpetual, cross-venue, and on-chain semantics require a separate taxonomy, data permissions, and validation rules, so they remain outside the equity-options core.
- Goldman Sachs, JPMorgan, Morgan Stanley, BofA, Barclays, UBS, and similar sell-side research normally require client or terminal entitlements. Connect them only through an authorized email/vendor route when the user already holds the required access.
- IMC, SIG, Old Mission, Akuna, Mako, Wolverine, and similar firms are strong institutions but currently lack a stable, searchable, regularly updated public finance-research archive with enough research density. A company-homepage-only catalog would add no discovery value, so re-check them only when their public state changes.
Whether an automated connector is enabled is determined by the repository's public configuration and the source's permission terms.
