Session control from marubozu and engulfing geometry

Rebuild who owned the session

A finished bar is treated first as a construction problem. From the open, high, low, and close, the reader rebuilds whether buyers or sellers controlled the session.

Display color is an illustration choice. Construction depends on body-versus-shadow geometry and on whether buyers or sellers controlled the full session.

Marubozu geometry

A marubozu is a single candle whose real body has no meaningful upper or lower shadow, so one extreme of the session is the open and the opposite extreme is the close.

A bullish marubozu is built as a long up body with no shadows, so the open matches the low and the close matches the high. That geometry is read as buyers owning the entire bar.

A bearish marubozu is built as a long down body with no shadows, so the open matches the high and the close matches the low. That geometry is read as sellers owning the entire bar.

Engulfing pairs

A bullish engulfing formation is a two-candle structure: a down candle immediately followed by a larger up candle that covers it.

A bearish engulfing formation is a two-candle structure: an up candle immediately followed by a larger down candle that covers it.

Impulse context and the completed close

Large directional candles used to flag impulse moves are described as uncommon in balanced, low-volatility conditions and more typical when the tape is already trending or volatile.

A breakout from balance is described as coinciding with a marubozu or an engulfing pair. The same constructions are also used to mark continuation after a pullback. In this workflow that bar or pair is the impulse-candle: a large directional bar or pair used to mark a break away from balance or a resumption after a pullback.

The setup treats the event as complete only after the qualifying marubozu or engulfing pair has closed, and it is specified on hourly or four-hour charts. The completed-close rule means the pattern is not treated as formed until the qualifying candle or second engulfing candle has finished.

Level-flip after a strong bar

A long, strong up candle is read as a resistance break that may later act as support. A long, strong down candle is read as a support break that may later act as resistance. That reading is the level-flip in this workflow.
