xalpha is a Python library for full-lifecycle management of fund and stock investments, including fetching fund/stock net values and market data, recording and analyzing investment accounts, and simple strategy backtesting.

- visualize PE/PB valuation history for indexes and funds
- price convertible bonds
- get reminders for scheduled periodic investing
When to choose
