Important

E*TRADE uses OAuth 1.0a authentication — the consumer key/secret are your app credentials, but an OAuth access token must also be generated per-account and renewed periodically (tokens expire after inactivity).

Paper trading is available via E*TRADE's sandbox environment using separate sandbox credentials.

US equities and options: NYSE/NASDAQ session 09:30–16:00 ET; options expire on standard monthly/weekly cycles.

Rate limits apply per OAuth token; heavy polling of market data endpoints should be replaced with streaming subscriptions.

E*TRADE API v1 is legacy — ensure you are targeting the current API version in connector configuration.
