Market Phase exits upward
Transition runs a median of 1 session(s) (max 9) — this is session 2. 53% of exits went up.
Market Health crosses the 50 midline
MHI at 43.9 — a close back above 50 would end the 20th-percentile read.
Phase slips to Bear Market
19.6% of Transition exits went straight to Bear — the conditions analog's worst 5-session outcome (−6.11%) lives on that path.
