VeighNa Supports Multiple Market Data Services for A-Share Backtesting

Summary

This brief forum exchange answers whether VeighNa, also known as vn.py, requires Tushare as the sole source of historical A-share data for backtesting. The response says the framework supports multiple data services and points readers to its documentation for the available providers.

The exchange establishes that users have alternatives to Tushare, but it does not name those services or compare their coverage, cost, licensing, data quality, or integration effort. It therefore offers a useful direction for platform setup rather than a detailed data-selection guide. A researcher choosing a feed would still need to check which instruments and historical periods it covers and whether its format fits the intended backtest.

Key ideas

• VeighNa supports more than one market data service.
• Tushare is not presented as the only option for A-share historical data.
• The exchange does not compare provider coverage, cost, or data quality.
• Backtest users need to evaluate whether a provider's data fits their instruments and period.
