Wyckoff Method — The 5 Phases of Accumulation (Part 2)
Accumulation Phases A, B, C, D, and E each have distinct candle signatures. A Spring is the point where stop-loss orders below the range are absorbed and the last remaining supply is cleared.
> A *Spring* is the point where stop-loss orders below the bottom of the range are absorbed and the last remaining supply is cleared.
In Part 1, we covered Wyckoff’s three laws — supply and demand, cause and effect, and effort versus result — along with the Composite Operator and the four-stage cycle of accumulation, markup, distribution, and markdown. This article breaks down the first stage, Accumulation, into five phases: Phase A, where the decline stops; Phase B, where the cause is built; Phase C, where the Spring and final Test occur; Phase D, where LPS and SOS appear; and Phase E, where Markup begins. Each phase has its own candle signature.
The common interpretation compresses these five phases into a simple story: “Smart money accumulates during a sideways range, one final Spring appears, and the trend begins.” That leads many traders to read a Spring as a failed breakdown, or to treat the long sideways action in Phase B as meaningless dead time. Both mistakes are expensive, and this is where the entire Wyckoff chart-reading framework starts to break down.
Look more closely and each Accumulation phase can be identified through price and volume signatures. PS, SC, AR, and ST in Phase A are the actual footprints of a decline coming to a stop. The long Cause in Phase B is the width of the cause built over time. The Spring in Phase C is the final stop-hunt and the true signature of accumulation. LPS and SOS in Phase D are the pullback and breakout just before the trend begins. The same bullish candle carries completely different information depending on whether it appears in the middle of Phase B or as an SOS in Phase D.

Phase A — The Four Events That Stop the Decline: PS, SC, AR, ST
Phase A is the record of the prior downtrend coming to a halt. A trend does not usually stop in a single candle. Four events need to unfold in sequence before the process is complete.
- PS (Preliminary Support): During a sharp decline, volume increases and either a bearish candle closes slightly above the prior candle’s close or a small bullish candle appears for the first time. This is the first trace of buyers stepping in. It does not stop the trend yet, but it becomes the reference point for the next event.
- SC (Selling Climax): Price falls another leg and prints a large bearish candle on volume 2 to 5 times the recent average. The close finishes clearly above the candle low, and the Composite Operator absorbs a large amount of panic selling. This candle defines the bottom of the range.
- AR (Automatic Rally): After the SC, selling pressure is exhausted and price rebounds automatically. Volume is clearly lower than it was during the SC. The AR high defines the top of the range, so the SC low and AR high become the reference lines for the range width.
- ST (Secondary Test): After the AR, price makes a second attempt to test the area near the SC low. Volume must be clearly lower than the SC, confirming that available supply has already been depleted. If the ST closes slightly above the SC low, Phase A is complete and the chart moves into Phase B.
SPY’s COVID panic SC near $218 on March 23, 2020 is a textbook example. Volume that day was more than four times the prior 20-bar average, and the candle closed clearly above its low. By March 26, the AR had rebounded toward $260. In early April, an ST was confirmed near $240 as volume fell to less than half of the SC volume.
Phase B — The Width of the Cause Creates the Effect
Phase B is the long stretch where the top and bottom of the range have been established and price oscillates inside them. It usually accounts for the largest portion of Accumulation in terms of time, lasting from a few weeks to several months.
The key is Wyckoff’s law of cause and effect. The time spent in Phase B is where the Cause is built, and the width of that Cause determines the size of the Phase E move, or Effect. This is why the horizontal count on a Point & Figure chart can become a candidate for the vertical price target. Even if two ranges have the same price width, a stock that finishes the range in four weeks and one that moves sideways for 16 weeks can have completely different target potential once the trend begins.
Inside the range, small up-thrusts above resistance and spring-like tests below support often repeat. If price briefly moves above the range on weak volume and quickly returns inside, it suggests there is not much supply waiting overhead. Conversely, if a downside probe happens on weak volume, it suggests supply has also disappeared below the range.
OBV reveals what is happening beneath the surface in Phase B. If price is flat inside the range while OBV gradually trends higher, it is strong evidence that the Composite Operator is accumulating. If OBV is flat or trending lower, the range is less likely to be true Accumulation. That is why Phase B cannot be read from price alone. OBV and volume on each candle must be analyzed together.
After AAPL fell toward $124 on January 3, 2023, it spent 11 weeks from January to March in a $130 to $150 range. Price moved up and down inside the range, but OBV maintained a clear upward slope during the same period. As the range high was tested two or three times, volume kept drying up. The Cause built over those 11 weeks matched the subsequent advance to $198 in July of that year with remarkable accuracy.

Phase C — The Spring Is the Composite Operator’s Planned Final Cleanup
The central event in Phase C is the Spring. Price briefly breaks below the bottom of the range and returns inside the range within a short period. This single event defines Phase C.
The common interpretation sees a Spring as a failed breakdown or a bounce after support is lost. Both readings miss the actual mechanism. A Spring is the move where price briefly drops below the range, absorbs the stop-loss orders stacked there, and clears the last remaining supply. Retail stop orders are concentrated just below the bottom of the range. This is a structural feature of markets that rarely changes. The Composite Operator cannot accumulate enough inventory to start the trend without absorbing that order layer.

There are three criteria for identifying a Spring.
- Shallow, brief break: It usually stops 1 to 3% below the range low and returns inside the range within one or two candles.
- Volume on the breakdown candle: It is either a high-volume Spring where absorption is aggressive, or a low-volume Spring where supply has already dried up and the move ends easily.
- Fast recovery: Immediately after the Spring, a bullish recovery candle returns quickly into the range with volume behind it.
A Test follows the Spring. Price drops once more toward the bottom of the range, but the key is that it does not break the Spring low. Test volume must be clearly lower than Spring volume. When the same area is tested again and almost no supply appears, it confirms that accumulation is complete. A Spring followed by a Test is the clean signature of Phase C.
BTC formed an exact Spring near $24,800 on June 15, 2023. After spending 11 weeks in a $26,500 to $31,000 range from March to June, the June 15 candle broke below the $26,500 range low, briefly fell to $24,800, then returned and closed at $26,800 within the same candle. The following week, a Test formed near $25,400 with volume falling to less than half of the Spring’s volume. From late June, BTC closed above the range high and the trend continued into Q4 of that year. If you read the Spring as a failed breakdown, you miss the entire entry area.

Phase D — Candle Signatures of SOS and LPS
Two events appear in sequence during Phase D: SOS, or Sign of Strength, and LPS, or Last Point of Support.
An SOS is a strong bullish candle that closes above the top of the range on strong volume. SOS volume is at least 1.5 to 3 times the Phase B average, and the candle’s range is clearly different from the candles seen inside the range. The candle itself is evidence that stronger buyers have entered, and it directly marks the end of the range.
LPS is the pullback after the SOS. After price breaks above the range high, it returns toward that former resistance area and holds it as support. This is the first test of whether the range high has flipped from resistance into support. If a bullish candle appears there on lower volume, it becomes the cleanest entry area in Phase D. LPS is the support point confirmed inside the BU, or Backup, after the SOS breakout. If BU is the entire process of retesting prior resistance in a bullish trend, LPS is the final point within that process where support actually holds.
LPS is attractive because the stop line is clear. The range high itself becomes the stop reference, and if the LPS candle low stays above it, entry risk is tightly defined. By contrast, entering immediately at the SOS close usually creates a wider stop because the SOS candle itself is long. That is why the most efficient Phase D entry is the LPS. The SOS is better treated as a signal that confirms the market’s state and tells you to wait.
> NVDA daily has moved sideways for more than six weeks after a prior major decline,
> and OBV has maintained a clear upward slope during the range.
> A Spring candle briefly breaks below the range low and closes back inside the range.
> The following week’s Test candle shows volume reduced to 50% or less of the Spring’s volume.
> An SOS appears, closing above the range high on more than twice average volume.
> When price later pulls back toward the range high,
> enter long where the LPS candle closes above the range high.
> Place the stop 1 ATR below the range-high line.
> Exit if price closes back below the range high.
After NVDA fell toward $132 in January 2023, it spent about 16 weeks from January to May in a range around $150 to $170. On May 25, an earnings gap produced a strong SOS that closed above the range high. Over the next few days, an LPS formed near the range high on declining volume. A position entered at the LPS candle close could have followed the trend to $482 by August of that year.

Phase E — Trend Entries in Markup and the Re-Accumulation Trap
Phase E is where the range ends and price begins a full markup phase. Early in Markup, an initial rally appears. Because the trend has just broken out of the range, momentum is strongest, and a series of candles with volume clearly above the range average often follows. At this stage, the most efficient approach is for traders who entered in Phase D to keep holding the position.
The middle of the move brings mid-trend pullbacks. Price briefly retraces toward the 50% or 38.2% level of the prior advance and finds support on lower volume. These mid-trend pullbacks often overlap with the Phase B range high, where old resistance acts as new support, or with the prior LPS area. That makes them candidates for add-on entries or scale-in buys.
There is one common whipsaw trap during Markup. Small ranges, or Re-accumulation structures, often appear during the trend. These Re-accumulation ranges repeat Phases A through E on a shorter time frame. If you mistake Re-accumulation for the end of the trend and exit, you miss the largest part of the Markup. There are two criteria for distinguishing Re-accumulation: whether OBV continues to trend higher inside the range, and whether the price range stays above the prior LPS. If both conditions hold, the range is preparing the next leg.
The signal that Markup is ending mirrors the Phase A signature of Distribution, which we will cover in Part 3. Buying Climax (BC), Automatic Reaction (AR), and Secondary Test (ST) appear near the end of an uptrend. When these events are confirmed through candle signatures, they mark the end of Phase E and the beginning of Phase A in a new range.
Three Common Traps in Phase Identification
- Trap 1: Treating Phase B range oscillation as an entry signal: The most common loss pattern is buying a small upward move or range-high test in the middle of Phase B after mistaking it for an SOS. An SOS refers only to a breakout above the range high after both the Spring and Test are complete. If a test of the range high lacks volume, it is only range noise.
- Trap 2: Entering a range that moves into Phase D without a Spring: Not every Accumulation structure must have a Spring, but a range that breaks above resistance without one has a clearly lower-quality Phase D setup. A breakout that has not shown evidence of absorbing the last supply has a higher chance of becoming a false breakout. For ranges without a Spring, entries should require an extra layer of confirmation.
- Trap 3: Entering before the LPS candle closes: The key to an LPS entry is the event of a close above the range high. If you enter while the candle is still forming simply because price is near the range high, that candle can easily close back below the range high, triggering an immediate stop-out.
Two Ways to Improve Phase Diagnosis
Measure the Cause width with a P&F chart. Wyckoff’s original method converts the time width of the range into a vertical price objective. The horizontal count on a P&F chart represents the size of the Cause built inside the range, and adding that count above the range high produces a candidate target. An 11-week Phase B and a 4-week Phase B may show the same Spring and SOS signatures, but their reachable targets are clearly different. Adding P&F analysis helps you identify Phase E exit areas earlier.
Confirm the accumulation area with Volume Profile. If the POC, or Point of Control, in the range sits in the upper half of the range, it reinforces the idea that accumulation took place higher in the structure. If it sits in the lower half, you also need to consider the possibility that distribution is underway. If OBV shows accumulation through time, Volume Profile shows accumulation by price. Used together, the two tools filter out another layer of false positives in phase identification.
