A TensorBoard dashboard for visualizing and comparing Zipline algorithmic trading backtests in real-time.
Zipline-TensorBoard is an integration that enables TensorBoard, TensorFlow's visualization tool, to serve as a real-time dashboard for Zipline algorithmic trading backtests. It allows traders to monitor live portfolio metrics, compare multiple trading strategies, and visualize custom-recorded variables during backtest execution. The tool solves the problem of gaining immediate, visual insights into backtest performance without building custom dashboards.
Quantitative traders, algorithmic trading developers, and financial researchers who use Zipline for backtesting and want enhanced visualization capabilities for strategy analysis and comparison.
Developers choose Zipline-TensorBoard because it provides a ready-to-use, powerful visualization layer for Zipline backtests using TensorBoard's established interface, eliminating the need to build custom monitoring tools while enabling real-time strategy comparison and deep performance analysis.
TensorBoard as a Zipline dashboard
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Displays live portfolio statistics, returns, and positions as backtests execute, allowing immediate feedback during strategy development, as shown in the README with live stats updating in TensorBoard.
Enables side-by-side visualization of different parameterizations on shared charts, facilitating quick performance analysis, evidenced by the example image comparing several strategies in the README.
Logs any variable recorded via `algo.record()` and displays it alongside default metrics, offering flexibility for custom analysis, as demonstrated with the x_bar variable example.
Allows grouping and filtering of metrics by name patterns, making it easier to focus on specific aspects, with the README showing an example filter for stats with 'number' in the name.
Requires installing TensorFlow, a large deep learning library, even if only using TensorBoard for visualization, adding unnecessary bloat and setup complexity for pure trading applications.
Converts trading dates to ordinal epochs for alignment, resulting in an x-axis that looks weird and may confuse users expecting standard date formats, as admitted in the README.
Default data flush interval is 120 seconds, meaning updates during backtest execution are not instantaneous and require manual refresh, as noted in the README with the flush_secs setting.
