Identical Three Crows (CDLIDENTICAL3CROWS)

Summary

A three-candle bearish reversal pattern: three consecutive declining black candles, each with a very short (or no) lower shadow, where each candle after the first opens at or very near the prior candle's close. A hit signals a bearish reversal (pattern is always bearish).

Outputs

• outInteger: pattern_bull_bear · zero · negative

Notes

• Does not verify the preceding uptrend that the bearish reversal classically assumes.
• Does not require the three bodies to be equal in size; 'identical' refers only to each candle opening at or near the previous candle's close.
• Rare in Bulkowski's tests: he ranks it 83rd of 103 patterns by how often it occurs (Identical Three Crows). It fires more often in crypto: 180 times in about 16,000 daily bars.

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 when the pattern is detected (always bearish), 0 otherwise. Never emits +100

Output Values

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

Value	Meaning
-100	Identical Three Crows pattern detected: bearish
0	No pattern
