The D2 Sweep explained: why every reversal is not valid

A D2 Sweep forms when price sweeps the range candle's high or low and the body closes back through the swept level, back inside the range, on the same candle. The rule is simple and applied strictly: geometry without location is noise, and location without confirmation is a candidate, nothing more.

D2 is the second stage of the four-candle fractal model: D1 Range, D2 Sweep, D3 Expansion, D4 Continuation. The D stands for Davidovich.

The rule

Two observations, judged only at the close:

1. Price trades through the range candle's extreme. That is the sweep.
2. The body closes back through that swept level, back inside the range.

Bullish: through the range low, close back above it. Bearish: through the range high, close back below it.

The rule is color-agnostic. Candle color is irrelevant: a green candle can be a bearish D2 Sweep. Until the candle closes, an apparent close back inside can still turn into a breakout. A close beyond the level (the body finishes past it, with acceptance outside the range) is the opposite verdict on the same excursion.

The close back inside must come on the sweep candle (the D2 Sweep) or on the candle after it (a D3 Expansion; see D3 Expansion and D4 Continuation). Later than that, the candidate is deleted and is not a setup.

If sweeps are new to you, start with sweeps explained.

The location requirement

Markets print sweep-and-close-back-inside candles all day inside ordinary ranges. Qualification follows a strict precedence:

1. Confirmed swing high or low. Established structure that has not been swept.
2. Active directional gap. When no qualifying swing applies.
3. The immediately swept opposing reference candle. A fallback only, when neither higher-order location exists.
4. The trailing 20-model-candle range extreme. FMP+'s final fallback for a trend-colored blow-off top or bottom when no higher-priority structure exists.

The fourth test is an FMP+ operational rule rather than a published source rule. The qualification belongs to the original sweep. A delayed confirmation can never search forward for a better location to rescue an invalid setup.

Confirmation: the trigger close

Mark the open of the last opposing chart-timeframe run into the sweep. That is the trigger line. Confirmation is the chart timeframe's body close through it, above it for bullish setups and below it for bearish. A wick is not confirmation, and neither is a zone touch.

Confirmation can print while the model candle is still forming. The first confirmed chart close that carries both facts (the close back inside and the trigger close) is an early read, and its alert fires at once. With no active setup, it draws in color at once. While another setup is active, that setup keeps the chart and the early read is called out at the right edge at its swept level, for example D2▼ early · 4H high swept. After a finished setup whose D4 followed through, an opposite-direction early read is called out the same way. The model-timeframe close then installs the record. An early read describes timing; it never relaxes the body-close rule. Full rule: the trigger close explained.

The operating order

1. Directional bias
2. Model-timeframe structure and location
3. The sweep and the close back inside
4. The trigger close
5. Objective, invalidation, risk

Skip the first two and this becomes pattern hunting.

Validation checklist

• Range. Its exact high or low defined?
• Sweep and close. Body closed back through the swept level?
• Location. Confirmed swing, active gap, opposing-candle fallback, or the final FMP+ range fallback at the original sweep?
• Trigger close. Chart timeframe closed through the trigger line?
• Invalidation and risk. Written down before entry?

Common mistakes

• Counting the second candle on screen as the D2 Sweep. Designation comes from role, not order.
• Accepting a wick or an unfinished candle as a close back inside.
• Attaching a new location after the fact.
• Using candle color as confirmation.
• Treating an early read as a finalized record.

FAQ

Does the D2 Sweep need to be the opposite color of the range candle?

No. Direction comes from the side swept and where the body closes. Color is irrelevant.

Can the trigger close arrive after the D2 Sweep closes?

Yes, but only by the close of the D3 window, the model candle after the sweep candle. It keeps the original sweep's geometry and location. A trigger close later than that is too late, and the candidate expires quietly.

Why did a valid D2 Sweep fail?

Validity means the rules were met, not that the outcome was owed. Well-defined setups fail; that is what invalidation is for.

Closures organize information; they do not predict outcomes. Define maximum loss before entry. Stops can fill at worse prices in fast markets. FMP+ tags a confirmed D2 Sweep at the sweep wick, for example D2▲³ (the arrow for direction, the superscript for the 0 to 3 score).
