Release v11.0.0-pre.0

Version 11 is a pre-release that provides the REST API and SSE support for the latest Alpaca OpenAPI specifications. WebSocket support for streaming market data and trade updates is coming soon. Previous versions had WebSocket support via OkHttp, but this library has switched to using Java's native HttpClient and WebSocket support is still a WIP.

10.0.1

Release Notes

10.0.1 contains several minor updates and bug fixes. Most notably, the alpacaAPI.trader().accountActivities() endpoint now works properly.

10.0.0

Release Notes

10.0.0 is a big update with lots of new features and improvements. This version update contains many breaking changes from the previous 9.2.0 version so refer to the updated README for the new documentation and the changelog below.

What's New

• Full Broker API support, including SSE streaming.
• Options API support.
• New market data APIs support.
• News streaming support.
• New websocket streaming interfaces.
• Java version updated to 17.
• Bug fixes and other improvements.
• BigDecimal usage.

What's Changed

• The REST API Java client is now generated using the OpenAPI Java generator with the okhttp-gson library. Alpaca's v1.1 OpenAPI specifications are available here. Model classes and API interface classes are located in the the net.jacobpeterson.alpaca.openapi package now. Note that these specifications may contain some issues, so if a REST API call isn't working properly, open a new issue or contact Alpaca with a request to fix the spec.
• Websocket listener interfaces now have discrete method calls for each type of message instead of one call with the message type as a parameter.
• The use of the alpaca.properties classpath file has been removed.
• ZonedDateTime has been replaced with OffsetDateTime.
• The group ID is now net.jacobpeterson.alpaca instead of net.jacobpeterson. The artifact ID is still alpaca-java.
