Indicator correctness used to be validated with charts, spot checks, and a few sample vectors. That is no longer enough for teams treating strategy generation as a software pipeline.
What Is Changing
Projects are adding bit-exact regression fixtures, cross-framework comparison harnesses, and failure reports tied to known market datasets. The goal is to detect semantic drift before it contaminates strategy research.
Why This Matters for Products
A benchmark claim is not credible if the underlying indicator suite is unstable. Tight regression discipline is becoming part of the trust story for open-source quant engines.
Expected Direction
As engines compete on research reliability, their public documentation will likely start highlighting test architecture and reproducibility guarantees alongside raw performance metrics.
