ml_levels Level-quality gates & structure classifiers

251
The small shared decisions that separate a REAL level event from noise: sweep-vs-break, displacement-confirmed impulse, retest-holds, volume validation, and nearest-level proximity. One vocabulary so “swept”, “broke”, “retested and held” and “validated pivot” mean the same thing across every SMC / order-block / support-resistance script.

Design: pure classifications over the bar geometry / volume you pass — no drawing, no persistent object state (level DETECTION and its box/line lifecycle stay host-side; this library judges the events). Nothing repaints: every read is a function of closed-bar values. Pair each event with a forward test before trusting it.

Concept credit: liquidity sweeps / stop-hunts, break-of-structure, order-block displacement and flip-then-retest are public Smart-Money-Concepts / price-action ideas — this is an original, dependency-free Pine v6 packaging of them. Educational; not financial advice.
