The engagement

This redacted engagement built an auth-walled research engine for a registered investment adviser. The system refreshes vendor market data, waits for the latest closed session to settle, evaluates signal and breadth scans over configured market universes including S&P 500 constituents, and sends daily digests only after the run is deliverable.

01

The challenge

The adviser needed a repeatable attention-director, not an overfit trading promise. Market data could be closed but not settled, scan inputs could be incomplete, and private research output had to stay behind login while still producing useful daily summaries.

02

The approach

The nightly script runs ship, market-data state, delivery-state, scan, signal-digest, and scan-email steps in order. If the ingested as-of date is earlier than the expected closed session, the job exits with a retry-later status before scans or email. If that date is newer than expected, it fails closed. A state file prevents duplicate deliveries for the same as-of date, and failures send an internal ops notice instead of quietly skipping the job.

Scope of work

  • Auth-walled static research site with credential-derived signed sessions
  • Vendor-data refresh with settlement probing before a session becomes ingestible
  • Signal rendering and breadth scan outputs over configured market universes
  • Nightly delivery state, signal digest, scan digest, and fail-closed ops notices
  • Abstract public portfolio cover with no private chart or signal data

04

What we delivered

  • Nightly refresh, scan, and two-message delivery pipeline
  • Settlement gate that retries later when the vendor feed has not settled the expected session
  • Scan registry with 11 buildable saved scans plus explicit unavailable-scan explanations
  • S&P 500, S&P 400, S&P 600, and ETF universe loaders with validation
  • Signed-cookie login middleware that fails closed when credentials are missing
  • Delivery-state file that records delivered as-of date, signal count, scan-new count, and timestamp

05

The result

  1. 01

    The adviser receives attention-directing daily outputs only after the input session is settled and the delivery state is safe.

  2. 02

    Duplicate digest delivery is avoided by checking the last delivered as-of date before scans and email run.

  3. 03

    The system separates signal digest and universe-scan digest sends rather than merging unlike alerts into one message.

  4. 04

    Private chart, login, domain, and client details stay out of the public case study.
