data-routing

Automatically select a market data provider by applying a decision tree that maps symbol patterns to specific sources during backtest configuration and script execution. This routing mechanism checks token availability, network accessibility, and fallback priorities based on market type.

Fallback routing for market data sources works by evaluating token availability and network accessibility, then directing symbols to providers like tushare, akshare, or yfinance based on a priority chain tailored to the specific market type.

Yes, you can use providers like yfinance or ccxt without manual configuration. The routing mechanism automatically evaluates your symbols and selects the optimal source, ensuring data retrieval respects your current network restrictions and available tokens.

The best way to route crypto symbols to okx is to let the automatic data routing mechanism evaluate the symbol pattern. It determines the appropriate provider during script execution, ensuring selection respects token availability and network accessibility.

Market data source selection fails during backtest configuration when required tokens are missing or network restrictions block access to the designated provider. The routing mechanism checks these constraints and automatically applies a fallback chain based on market type.

You need a tushare token only if the automatic data routing selects tushare as the optimal provider for your specific symbols. The mechanism checks token availability and seamlessly applies fallback priorities to other sources if required tokens are absent.
