CDLSHORTLINE

Summary

Single-candle pattern: a short real body with short upper and lower shadows (a small-range candle). Not a directional signal — the output sign encodes candle color, not bullish/bearish sentiment. A hit only flags a small-range candle; the +/- sign is the candle's color (white/black), not a reversal or continuation call.

Formula

One candle at i, all three:

short real body: real body < the BodyShort average
short upper shadow: upper shadow < the ShadowShort average
short lower shadow: lower shadow < the ShadowShort average
If matched: output = candle color * 100 (+100 white, -100 black); else 0.

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 matching white candle (close>=open), -100 for a matching black candle (close<open), 0 when no pattern. Sign is candle color, NOT bullish/bearish
