All 2 closed MSFT round trips today’s engine produces in the replay window, winners and losers, newest first.

Validation numbers: the engine is tuned on the earlier 60% of this name's history and scored on the later 40%, after costs with next-day fills. That tail was originally withheld but reused in later research, so it is not a pristine unseen test. Backtested, not live. Replay rows are BUY-to-SELL round trips regenerated nightly from end-of-day data; losers stay listed. Method on the methodology page; the row-level artifact is in validation JSON; every name’s current-rule replay slice is on the historical replay page. Hesper Atlas is an educational publication with one systematic signal per name, identical for everyone. It is not financial advice and does not know your situation.
