Why New and Legacy Money Flow Factors Differ

Summary

The document addresses whether a newer platform factor, netflow_amount_large, exactly replaces the legacy mf_net_amount_xl factor. The answer is that the two are not identical: the old and new money flow factors use different data sources and different processing standards.

This is a brief clarification rather than a factor specification or empirical comparison. It does not describe the calculations, quantify the differences, or identify a fully equivalent replacement. Researchers migrating strategies should therefore avoid assuming the similarly named factor preserves the old signal and should validate any substitution against their own data and use case.

Key ideas

• The newer large-net-flow factor is similar to the legacy factor but is not fully equivalent.
• The old and new factors differ in their underlying data sources.
• Their processing standards also differ, so direct substitution may change a strategy's inputs.
