CORD20 CORD

Change of price-volume correlation (short minus long)

Formula

Corr($close/Ref($close,1), Log($volume/Ref($volume, 1)+1), 20)

The expression above is verbatim from qlib Alpha158/360 feature engineering (qlib/contrib/data/loader.py, Apache-2.0). The platform qlib-compatible expression engine evaluates it on the deterministic research panel.
