The E*TRADE from Morgan Stanley Market Data API is the market-data module of the public E*TRADE V1 REST platform. It provides real-time and delayed equity and option quotes, option chains, and product/symbol lookup so applications can price instruments, research securities, and build watchlists and analytics. Like the rest of the E*TRADE surface it is authenticated with OAuth 1.0a on behalf of an E*TRADE account holder, documented with in-portal Swagger, and exercisable against the apisb.etrade.com sandbox before the api.etrade.com production host. Market-data access is subject to the E*TRADE API Developer Licensing Agreement and exchange entitlement rules. This is a public developer surface within the Morgan Stanley group.
