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.

Outputs

• outInteger: pattern_bull_bear · zero · positive · negative

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)

Inputs

• inOpen — Open price of each bar
• inHigh — High price of each bar
• inLow — Low price of each bar
• inClose — Close price of each bar

Outputs

• outInteger — +100 for a white (bullish) closing marubozu, -100 for a black (bearish) one, 0 otherwise

Output Values

What candlestick values mean: Candlestick Outputs. The function's flags declare which values it can return: rW7.

Value	Meaning
-100	Closing Marubozu (bearish) — closes right at the session low, sellers in full control into the close
0	No pattern
100	Closing Marubozu (bullish) — closes right at the session high, buyers in full control into the close
