  title: Polygon Crypto Daily Comparison
  summary: Check market status, snapshot a crypto pair, and read its daily open/close.
  description: >-
    A crypto daily-comparison flow that frames a pair's session against
    overall market context. The workflow checks the current market status,
    reads the crypto pair's live snapshot to capture its day session, and
    reads the pair's open/close for a specific date so the live snapshot can
    be compared against a fixed historical session. Every step spells out
    its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
