Shooting Star (CDLSHOOTINGSTAR)

Summary

Single-candle pattern: a small real body with a long upper shadow and little-to-no lower shadow that gaps up from the prior candle's real body. Bearish reversal signal. A hit (-100) flags a bearish reversal at the top of an uptrend.

Outputs

outInteger: pattern_bull_bear · zero · negative

Notes

A preceding uptrend is not verified.
Bulkowski found this reverses only 59% of the time — "near random," summarized in his words as "this candle looks better than it performs" — ranking 55th of 103 patterns. (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 when the shooting star is detected, 0 otherwise. Only ever emits negative (bearish); never +100

Output Values

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

Value	Meaning
-100	Shooting Star pattern detected: bearish
0	No pattern
