Volume Analysis — Profile, Order Flow & Wyckoff

Three complementary methodologies for complete volume-based analysis:

1. Volume Profile — Price-level volume distribution (POC, VAH, VAL, HVN, LVN)
2. Order Flow & Delta — Cumulative delta, absorption detection, delta divergence
3. Wyckoff Method — Accumulation/distribution schematics, spring/upthrust, phase detection

These form a complete picture: where volume transacted (profile), direction of aggressive orders (delta), and institutional intent (Wyckoff).
