Please do not download banbot from the Releases page. You can quickly try it out using Docker or build it locally by following the documentation. This page only provides the front-end static assets file (dist.zip).

Banbot will download this file automatically on startup. Alternatively, you can download it manually, unzip it into your BanDataDir directory, and rename the resulting folder to uidist (ensure uidist/index.html exists). Finally, create a version.txt file in that directory and write the current version number inside it.

New Features

• Support for specifying a finer execution/matching interval (refine_tf)
• Support for custom instrument filters
• Toggle for parallel OnBar execution: core.ParallelOnBar
• Backtesting now shows Top-10 maximum drawdowns
