Sign of Strength (SOS)
Overview
A Sign of Strength is a strong rally within or out of an accumulation range that occurs on expanding volume and wide price spread. It confirms that demand has overcome supply and that the accumulation phase is likely complete. The SOS typically breaks above the range's resistance (Creek) and is followed by a Last Point of Support (LPS) pullback.
Key Concepts
Strong rally with wide price spread, Expanding volume on the advance, Breakout above the trading range resistance ('jumping the Creek'), Usually follows a successful Spring or Phase C test, Often accompanied by bullish volume divergence
Entry Signals
Buy after the SOS confirms a Spring/test sequence, Buy on the LPS pullback after the SOS breakout, Volume should expand significantly on the SOS bar/bars, Compare volume to prior rally attempts within the range (should be highest)
Exit Signals
Stop below the most recent support level within the range or the Spring low, Target the measured move (range height added to the breakout point), Trail stops using rising support levels
Best Timeframes
Daily for the SOS identification, 4H for precision entry on the LPS
Pro Tips
A genuine SOS should have notably different character than prior rallies within the range — wider bars, higher volume, and faster pace. If the SOS looks similar to range rallies, it may be a trap.

Accumulation Schematics
Wyckoff Accumulation is the phase where institutional operators quietly buy large positions without driving price up. The schematic includes: Preliminary Support (PS), Selling Climax (SC), Automatic Rally (AR), Secondary Test (ST), Spring/Shakeout, Sign of Strength (SOS), Last Point of Support (LPS), and the eventual Markup phase.
The Three Wyckoff Laws
Richard Wyckoff's three fundamental laws — the Law of Supply and Demand, the Law of Cause and Effect, and the Law of Effort versus Result — form the philosophical foundation of the Wyckoff Method. These laws explain why prices move, how far they are likely to travel, and whether a move is genuine or likely to fail. Every Wyckoff analysis technique derives from these three principles.
Composite Man Theory
The Composite Man is Wyckoff's conceptual framework for understanding market manipulation. Wyckoff proposed viewing the market as if a single, all-powerful operator orchestrates every move — accumulating at low prices, marking up, distributing at high prices, and marking down. While no single entity controls the market, aggregating institutional behaviour creates patterns that appear coordinated.
Wyckoff Market Cycle
The Wyckoff Market Cycle consists of four phases that repeat across all markets and timeframes: Accumulation (smart money buying), Markup (trending up), Distribution (smart money selling), and Markdown (trending down). Understanding which phase the market is in helps traders align with institutional flow.
