Prerequisites
Sign of Strength (SOS) (symmetric), Distribution phases A–E.
Definition
In plain terms — A convincing drop with volume: sellers do not just hold price, they push it down with force — typically toward or past range support.
A Sign of Weakness (SOW) is a bearish move toward (or slightly past) the trading range support, usually with widening spread and increasing volume.
- Appears in distribution phase D
- Often follows a UTAD or a phase C test
- The initial AR + first SOW = change of character — supply dominant
- Often breaks internal ICE support, turning it into resistance for later rallies
SOW vs generic pullback
| Wyckoff SOW | Any pullback | |
|---|---|---|
| Context | Distribution phase D | Any |
| Volume | High on the decline | Variable |
| Position | Post-UTAD / mature range | — |
| Follow-up | LPSY expected | Uncertain |
Example — After a UTAD at €80, a bar closes at €74 on volume 2× the average with a wide downside range: SOW — a possible imminent markdown.
Operational sequence
- Complete distribution phases A–C
- UTAD or UT (phase C)
- SOW — supply confirmation
- LPSY — weak bounce, short zone
- Support breakdown → phase E markdown
Caution — Longs in phase D with active SOW = high risk. Wyckoff: «whoever stays long is asking for trouble».
Symmetric
Sign of Strength (SOS) in accumulation.
