  The public E*TRADE from Morgan Stanley developer platform ships a full sandbox.
  The invitation-only Morgan Stanley institutional API Platform provisions
  per-client sandbox endpoints during onboarding (not publicly documented).
sandbox:
  provider: E*TRADE from Morgan Stanley
  host: https://apisb.etrade.com/v1
  production_host: https://api.etrade.com/v1
  separation: >-
    Live and sandbox are separated by host AND by credentials - the sandbox
    requires its own OAuth consumer key + secret, distinct from production keys.
    Sandbox OAuth endpoints live under apisb.etrade.com/oauth.
  behavior: >-
    The sandbox lets developers exercise the REST API and validate request/response
    syntax, sample responses, and deserialization logic WITHOUT executing real
    transactions in live markets. Responses are canned sample data keyed to the
    request shape rather than live account/market values.
  oauth:
    request_token: https://apisb.etrade.com/oauth/request_token
    access_token: https://apisb.etrade.com/oauth/access_token
  covers: [Accounts, Market Data, Order, Alerts]
  caveats: >-
    Sandbox returns representative/sample payloads; values are not live and order
    placement is simulated. Real trading requires production keys and account
    entitlements.
notes: Never invent test values - E*TRADE sandbox returns server-side canned data, not fixed magic tokens.
