Accumulation Schematic A: Phase-by-Phase Walkthrough with Event Markers

Accumulation Schematic A is the most recognized Wyckoff pattern. It describes how smart money accumulates a position in a downtrend before marking up the price. Each phase and event has a specific diagnostic purpose; knowing them lets you locate where price is in the accumulation process and when to enter.

Phase A: stopping the downtrend.

• Preliminary Support (PS): initial buying slows the decline. Volume increases but price still falls. Not yet a buy signal.
• Selling Climax (SC): panic selling on very high volume, often a wide spread down bar that closes off its lows. Smart money begins absorbing.
• Automatic Rally (AR): rebound from the SC as oversold conditions ease. The AR's high and the SC's low define the trading range.
• Secondary Test (ST): price revisits the SC area on lower volume to confirm the selling pressure is exhausted.

Phase B: building the cause. Multiple tests of the range boundaries where smart money accumulates. Price swings between support (SC low) and resistance (AR high) for weeks to months. Do not trade every swing; the cause is being built, not yet released.

Phase C: the spring. The defining event. Price breaks below the SC low (support) on reduced volume to shake out remaining holders, then quickly reverses back into the range. The Spring confirms that supply is exhausted. Variants: a Spring that holds above the SC low is a "spring above support," still valid but weaker.

Spring validation. A valid Spring shows lower volume than the SC on the break below support, a quick recovery into the range (within 1-3 bars), and a close back above the SC low. A Spring that stays below support on heavy volume is a breakdown, not a Spring.

Phase D: the markup begins.

• Test of the Spring: a minor pullback on low volume confirms supply is gone.
• Sign of Strength (SOS): a rally on increasing volume toward the AR high.
• Last Point of Support (LPS): a pullback to a higher low above the Spring, on diminishing volume. This is the highest-probability entry point. Stop goes below the Spring; target is the range top and beyond.

Phase E: breakout. Price breaks above the AR high (resistance) on increasing volume. The accumulation is complete. The measured move from the cause projects the markup target.

Entry rules.

• Conservative: enter at the LPS in Phase D, after the Spring test confirms. Stop below the Spring low. Target the AR high, then the cause projection.
• Aggressive: enter at the Spring reversal, stop below the Spring low. Higher risk, earlier entry.
• Breakout: enter on the Phase E break of resistance with a close above the AR high. Stop at the last LPS.

Invalidation. The accumulation fails if price closes below the Spring low on heavy volume after the Spring, or fails to hold the LPS during Phase D. Most losses come from entering during Phase B, treating range swings as directional trades—wait for the Spring and LPS before committing risk.
