Long Legged Doji (CDLLONGLEGGEDDOJI)

Summary

Single-candle doji (open ~ close) with at least one long shadow. Signals market indecision, not a directional bias. Marks indecision/uncertainty; not inherently bullish or bearish despite the positive sign.

Outputs

outInteger: pattern_bool · zero · positive

Formula

One candle. Hit when: real body <= BodyDoji average (doji body) AND (lower shadow > ShadowLong average OR upper shadow > ShadowLong average), i.e. at least one long shadow.

Notes

Only one long shadow (upper or lower) is required, whereas the classic pattern shows both long upper and lower shadows.
Bulkowski's testing found this continues in the direction of the prior trend only 51% of the time — statistically random — and ranks 37th of 103 patterns overall; in his words, "it means nothing." (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 pattern is present, 0 otherwise. Only +100 is emitted; the code never emits -100, and the positive sign does NOT mean bullish

Output Values

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

Value	Meaning
0	No pattern
100	Long-legged doji detected — signals market indecision, not a directional (bullish/bearish) bias
