# Get Signum Rgg Archive

`GET /api/v1/backtesting/signum-rgg`

## Request

- Base URL: `https://cryptodataapi.com`
- URL: `https://cryptodataapi.com/api/v1/backtesting/signum-rgg`
- Auth: API key in header `X-API-Key`

Per-day SIGNUM_RGG colour state for the full universe, from the daily archive.

Thin wrapper over ``/backtesting/daily-snapshots/{date}`` that returns only
its ``signum_rgg`` block, split into ``summary`` (counts, breadth, top
lists) and the full ``by_symbol`` map (colour, signed score, ADX/DI,
days_in_color, flipped_at, price, ``hl_symbol`` join key). Available for
every archived day (the block has been stored since 2026-03-02).

``computed_from`` (present on days archived from 2026-09-09) is the last
COMPLETED daily bar the colours were read from; the archive is built at
20:00 UTC, so a day's block carries the colours completed through the
previous UTC close. Days before that were archived with the forming bar
included. Same auth gate as ``daily-snapshots``. 404 (with ``Retry-After``
while today's build is pending) when the day has no snapshot, and 404
when a snapshot exists but predates the SIGNUM block.
