Diagnosing Missing Market Factors in an Index-Based Quant Strategy

Summary

A user asks about an error in a shared quantitative strategy. The response points to a mismatch between the data universe and the requested features: index data does not provide certain return and price fields that are available for stocks, futures, or funds. This suggests that the strategy is attempting to access factors unsupported by its selected input data.

The response also recommends collecting the desired factors explicitly in the input-feature list and refers the user to a sample strategy template. It offers practical workflow guidance for tracing a feature or schema problem, but does not identify the specific exception’s technical cause, show corrected code, or report whether the suggested changes resolved the issue. The advice is tied to the platform’s data and feature modules, so the exact available fields should be checked against the chosen dataset.

Key ideas

• Index datasets may not contain price and return fields available in other asset datasets.
• Feature requests should match the schema of the selected data source.
• The response recommends explicitly listing the factors required by the strategy.
• The page does not provide a verified fix for the reported exception.
