FALLEN Fallen — broke its own criteria; kept on purpose
Trades taken with a GDI score of 80 or more were 31.0 % over break-even against 18.3 % otherwise — a result that cleared Bonferroni over 253 combinations and the half-split test. It was composition: one exchange contributed 556 of 557 trades to the low bucket. With instrument and day held fixed, p = 0.49, and 0 of 253 combinations survive.
