2.2.1 - Adjusted Price Data Validation Fix
Release date: 2026-08-01.
繁體中文
- 經調整價格可以正常載入。 使用 yfinance 的股息及拆股調整價格時，極微小的數值誤差不再被誤判為不合法，相關回測可以正常開始。
- 資料品質檢查仍然嚴格。 真正不符合開高低收關係、缺失或無效的價格資料仍會令回測停止並顯示錯誤。
English
- Adjusted prices now load correctly. Tiny numerical differences in yfinance dividend- and split-adjusted prices are no longer mistaken for invalid data, so affected backtests can start normally.
- Data-quality checks remain strict. Prices with genuinely invalid open-high-low-close relationships, missing values, or invalid values still stop the backtest with an error.
