SUMD10 SUMD
Difference of upward and downward contributions
Formula
(Sum(Greater($close-Ref($close, 1), 0), 10)-Sum(Greater(Ref($close, 1)-$close, 0), 10))/(Sum(Abs($close-Ref($close, 1)), 10)+1e-12)
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.
