L0 API serves two main purposes:
- Replay your own file format with Bookmap.
- Connect Bookmap to your own datasource in real time (both for receiving data and trading)
Doing so requires basic Java knowlege, however file replay example that is available in this repository uses simple text format which you can convert data to using your favourite tools.
It's recommended to begin with this getting started guide.
After you install Bookmap javadoc will be available in C:\Program Files\Bookmap\lib\bm-l1api-javadoc.jar. You can also get it from Maven repository.
