Closing Marubozu (CDLCLOSINGMARUBOZU)

Summary

Single-candle pattern: a long real body whose closing end has no or very short shadow, so the close sits at the candle's extreme. A strong directional bar, not a defined reversal/continuation signal — white is bullish, black is bearish.

Formula

One candle. Requires: (1) long real body: real body > the BodyLong average; AND (2) very short shadow at the closing end: if white (close>=open) upper shadow < the ShadowVeryShort average [close at/near high]; if black (close<open) lower shadow < the ShadowVeryShort average [close at/near low].

Notes

Bulkowski's testing found Closing Marubozu continues in its expected direction only marginally more than chance — 52% for the black variant — which he calls "near random." (thepatternsite.com)
