## What it is

CSI Data — Commodity Systems, Inc. of Boca Raton, Florida — sells end-of-day market data through
Unfair Advantage, a Windows application that keeps a compressed database on your own disk, refreshes
it daily from CSI's servers, and exports into whatever charting or backtesting software you run. No REST endpoint, no JSON, no Python package: you buy a Windows program and the data
held inside it.

The dated-looking site invites the wrong conclusion. The published build log runs roughly monthly
through 27 August 2026 (version 2.10.8, build 1098), the licence agreement carries a December 2025
revision, and at 11:33 ET on 14 September 2026 the posting-status page had that morning's Asia
release marked delivered and every later slot still pending — the daily schedule running on time.

## Pricing

Two ladders plus a fee that is easy to miss. Silver bills monthly or annually and carries five years
of history monthly, ten annually, from $24/mo for a five-futures-five-stocks-five-funds Budget Market
Mix up to $79.50/mo for world futures. Gold is annual only and buys thirty years, $639 to $1,889. On
top of either sits a one-time licensing fee of $30 to $400 that is explicitly non-refundable, and
extra history is charged per year again.

The trial is 21 days for $20 rather than free. History-only orders skip updates altogether — $400 for
twenty years of NYSE stocks — and leave one month to export the files before access ends.

## Data & coverage

End of day only, with no real-time or intraday product at any price. Depth is the reason to be here: CSI's own Chicago Board of Trade factsheet, downloaded 14
September 2026, returns wheat beginning 1922-01-03 and corn 1946-01-02, both current through
2026-09-11, the last completed session. The NYSE factsheet holds 17,002 series, with Altria, Chevron
and BP starting 1962-01-02.

Breadth reaches most of the 110+ futures exchanges worldwide: roughly 1,400 active futures series,
80,000 stocks across the US, Canada and the UK, 20,000+ mutual funds, roughly 160 FX and 70 crypto cross-rates,
options on stock indices and 190+ futures, and Briese's Commitments of Traders series.

The continuous contract is what CSI is actually bought for, and it builds eight: back-adjusted,
forward-adjusted, proportionally back-adjusted, Nth nearest for a value of N you choose, the
time-weighted and open-interest-weighted Perpetual Contract (CSI's own trademark), the
Proportional Liquidity Perpetual, and Gann. Roll timing is yours to specify — calendar date, trading days relative to the
delivery month, days before expiry, or thresholds on volume, open interest or both. Nothing else in
this category exposes that many knobs.

## Integrations

Export is file-based: CSI's own format, MetaStock, ASCII and Excel, with xlsx added in January 2026.
Preconfigured portfolios ship for Trading Blox, Trading System Lab and RealTest, and 2026 builds
added AmiBroker export settings and nearest-futures-group contracts to TradingBlox catalog files.
Custom studies and scanner indicators are written in VBScript, JScript, Perl or CSI's own
AnyLanguage.

## Limitations

- **Windows only, and still a 32-bit application** whose stated requirements span Windows 98 through
  11. A virtual machine counts as a separate licensed device, so a Mac or Linux workaround costs a
  second licence.
- **Delisted stocks are off the menu.** The order form says they are no longer offered through the
  application and are a premium annual add-on arranged by email at an unpublished price; inactive
  futures are excluded from every package. The data plainly exists — 9,659 of the 17,002 NYSE series
  in CSI's own factsheet are inactive — but a survivorship-bias-free backtest starts with a phone
  call, not a checkbox.
- **Licensed, never owned.** Miss updates for two months and the licence is revoked and the software
  disabled. Redistribution, resale and multi-user use are prohibited, and CSI states that exported
  files are encoded to identify the source account.
- **Refunds are narrow**: licensing fees, extra history and options history are all non-refundable,
  and early cancellation is short-rated at double the monthly fee per month.
- **No single-stock options** — futures options and stock index options only, the latter through a
  separate FTP product at $125 per year per underlying.
- **Daily throughput is capped** at 49 to 150 futures markets and 7,500 to 10,000 equities depending
  on tier, a real ceiling for a wide cross-sectional scan.

## Alternatives

[Norgate Data](https://stockmarketstack.com/tools/norgate-data) is the closest comparison and the better buy if survivorship bias
is the whole point: delisted securities and historical index membership are a priced tier rather than
a phone call, though its futures history is shallower. [Kibot](https://stockmarketstack.com/tools/kibot) and
[FirstRate Data](https://stockmarketstack.com/tools/firstrate-data) sell files outright instead of renting them.
[AlgoSeek](https://stockmarketstack.com/tools/algoseek) and [Databento](https://stockmarketstack.com/tools/databento) go to intraday and tick rather than
daily bars.

## FAQ

### Is CSI Data still active in 2026?

Yes, and the dated evidence is first-party. The Unfair Advantage changelog lists builds shipping roughly monthly through 27 August 2026, the licence agreement was revised in December 2025, and on 14 September 2026 the posting-status page showed that morning's Asia release already marked delivered with the later slots still pending. The old-fashioned site is not a sign of abandonment.

### Does CSI Data have an API?

No. There is no REST endpoint, no JSON and no Python package. Data lives in a compressed local database maintained by Unfair Advantage, a Windows desktop application, and leaves it as exported files. FTP exists only for options history and for commercially licensed accounts.

### Does CSI Data include delisted stocks?

The data exists but is not in any package you can buy online. The order form states that delisted stocks are no longer offered through the Unfair Advantage application and are a premium annual add-on arranged by email, with no published price, and inactive futures are excluded from every subscription and history-only order.

### Can I redistribute or republish CSI data?

No. The licence forbids resale, redistribution, network use, publication, website presentation and derivative works, and classifies any of them as commercial use requiring a separate negotiated agreement. CSI also states that exported files are encoded to identify the source account.

### What happens if I stop subscribing?

Access ends. The software and database are licensed rather than sold, and the agreement requires an update at least once a month — fail to download for two months and the licence is revoked and the software is disabled until you reinstall and resubscribe.
