MARKET DATA

SEC-grade market intelligence, inside your trading desk

Q: Is ByteTrader's market data free?

Yes, inside the desktop app, on every plan including Free: the panels, the live event stream into your agents, and point-in-time reads in backtests. Using the data outside the app, with a Data API key, bulk export or event webhooks, comes with PRO, Founder and Lifetime. See Pricing .

Q: Where does the data come from?

From public-domain US government sources: SEC EDGAR (filings, the Form 13F and Financial Statement Data Sets, fails-to-deliver), the Bureau of Labor Statistics, the Bureau of Economic Analysis, the Census Bureau, the Federal Reserve (FOMC), the U.S. Treasury (FiscalData) and the Federal Register. ByteTrader parses and classifies it. Every row carries its source and links back to the original filing.

Q: Are these trading signals?

No. Filings, calendars and ownership data are information. ByteTrader's own trade signals are a separate event type, and they count only a few event types as catalysts (earnings, insider purchases, offerings and distress filings). Every newer event type is labeled informational and isn't scored until it passes validation. None of it is investment advice, and none of it promises a result.

Q: Can I backtest with it without look-ahead bias?

Yes. Every row has knownAt , the first moment it was public, following EDGAR's release hours (a filing accepted after 5:30 pm ET counts from 6:00 am ET the next business day, unless our live feed saw it sooner). Query any dataset with asOf and you get only what was knowable then. Fundamentals come as filed, so later restatements don't leak backwards.

Q: How far back does the history go?

SEC filing events go back to 2016. The newer datasets (calendars, 13F, fails-to-deliver, point-in-time fundamentals and text changes) build their history as they run, and older history is loaded in stages. The API reference explains how history rows are marked.

Q: Can I use the data in my own app?

With a PRO, Founder or Lifetime Data API key you can use it in your own research, applications and trading systems. Reselling or redistributing it isn't allowed; the Data API Terms have the details.

Offerings with the dilution worked out, insider trades sorted from routine to opportunistic, corporate events, earnings, IPO, FDA and macro calendars, 13F ownership, fails-to-deliver and point-in-time fundamentals. Parsed from SEC EDGAR and US government sources, free in the desktop app on every plan, and in your own code with a PRO Data API key.

Eight datasets from one filings pipeline

Each one is parsed from the filings and agency releases themselves, linked back to the source document, and stamped with the moment it became public.

Offerings & dilution

Every 424B prospectus, S-1 and S-3 shelf, ATM program, PIPE, Form D and S-8, parsed for size, price, discount to the last sale, warrants and dilution as a share of the stock outstanding. Plus an overhang view: shelf left, open ATMs, live warrants and 90-day raises.

/api/v1/offerings

Insider intelligence

Form 4 trades classed routine or opportunistic (the Cohen–Malloy–Pomorski method), with ownership after the trade and 10b5-1 flags, and ESPP-style plan buys flagged so you can leave them out. Form 144 sales tracked from notice to execution, and 10b5-1 plan adoptions and terminations from 10-Qs and 10-Ks.

/api/v1/insiders/*

Corporate events

Late filings, abrupt executive departures, auditor resignations, restructurings, terminated deals, tender offers, 13D/G stake changes with % deltas, delistings, going-dark filings, merger votes, spin-offs, vote results, SEC comment letters and material 6-Ks.

/api/v1/filings/*

Calendars

Forward earnings dates, estimated from each company's history and confirmed from its own announcement, with date changes flagged. IPOs and lock-up expirations, FDA PDUFA dates and advisory committees, shareholder meetings, ex-dividends, and the macro calendar: BLS, BEA and Census releases, FOMC meetings and Treasury auctions.

/api/v1/calendar/*

13F ownership

Institutional holders for any symbol, with quarter-over-quarter new, added, reduced and exited counts and institutional ownership %, plus every manager's 13F portfolio.

/api/v1/institutions/*

Fails-to-deliver

The SEC's fails-to-deliver data per symbol and settlement day, as a percent of shares outstanding, with a threshold-like flag and a spike event when a new file lands.

/api/v1/eod/fails-to-deliver

Point-in-time fundamentals

As-filed fundamentals from the SEC's Financial Statement Data Sets: TTM revenue, EBITDA, free cash flow, net debt, margins, returns and leverage, each row stamped with the moment it became public.

/api/v1/fundamentals/pit

Filing text changes

How much each 10-K and 10-Q changed from the last comparable report, in the risk factors, the MD&A and overall, and which risk-factor headings are new.

/api/v1/filings/text-changes

Built for backtests: every row knows when it became public

Look-ahead bias is the quiet killer of backtests: a strategy "sees" a filing hours or weeks before anyone could have. ByteTrader stamps every event, filing, calendar entry and fundamentals row with knownAt, the first moment it was public. Ask for any dataset asOf a moment in time and you get only what was knowable then.

EDGAR's release hours applied: a filing accepted after 5:30 pm ET (10 pm for Forms 3, 4 and 5) counts from 6:00 am ET the next business day, unless our live feed saw it sooner

Fundamentals as filed, from the SEC's Financial Statement Data Sets, so later restatements don't leak into the past

Amendments kept as their own rows and linked to the original

"Next earnings date as known on this bar", from the calendar's own history

SEC filing events back to 2016, with bulk NDJSON export for research

An 8-K accepted after hours

Thu 6:12 pm ET EDGAR accepts the filing after its 5:30 pm cutoff, so it's dated the next business day.
Fri 6:00 am ET knownAt: the official release. An asOf query for an earlier moment doesn't return it. (If our live feed saw it sooner, knownAt is that earlier moment.)
Fri 9:30 am ET Your backtest's first bar that can act on it.

From EDGAR to your agent

ByteTrader watches EDGAR for the forms that move stocks: 8-Ks, Form 4s, 424B prospectuses, 13D/G stakes, late-filing notices, Form 144s and Form Ds, within the SEC's fair-access rate limit. Each filing is classified, parsed and pushed to the app, your strategies, the SignalR stream and your webhooks.

In the desktop app

Market Calendar: earnings (estimated vs confirmed), economic releases, IPOs and lock-ups, FDA dates, shareholder meetings and ex-dividends

SEC Filings: every corporate-event type, filtered by type, severity or watchlist

Insiders: transactions, pending Form 144 sales and 10b5-1 plans, with open-market and opportunistic filters

Ownership: 13F holders quarter over quarter, and fails-to-deliver for a symbol

Chart markers: earnings, dividends, splits, offerings and insider trades on the price chart

Strategies: read point-in-time fundamentals, events and the calendar in backtests and live, and optionally hold new entries around high-impact macro releases

40 event types, honestly labeled

Every type streams into the app and your strategies, and to your webhooks on PRO. Types marked informational are delivered as information: ByteTrader's trade-signal model doesn't score them. New types stay informational until they pass validation.

One place instead of six subscriptions

Traders who code usually piece this together from separate products: a filings API, a dilution tracker, an insider screener, a 13F site, an earnings-date feed and an economic calendar, each with its own format, its own login and its own bill.

ByteTrader puts them in the app you already trade from, in one format, wired into your strategies and backtests, at no extra cost. The Data API is there when you want the same data in your own code.

Where it comes from

Public-domain US government data, parsed and classified by ByteTrader:

SEC EDGAR: filings, Form 13F and Financial Statement Data Sets, fails-to-deliver
Bureau of Labor Statistics, Bureau of Economic Analysis and Census Bureau: release schedules
Federal Reserve: FOMC meetings, statements and minutes
U.S. Treasury (FiscalData): auction schedules
Federal Register: FDA advisory committee meetings

Every row carries its source and links back to the original filing. We don't resell vendor feeds in these datasets, and CUSIPs are never published.
