Separating Lines (CDLSEPARATINGLINES)

Summary

A two-candle continuation pattern: the second candle opposes the first in color, opens at the same price as the first, and is a long-bodied belt hold. Bullish (white second candle) or bearish (black second candle) continuation signal.

Formula

Two consecutive candles i-1, i: (1) opposite colors: color(i-1) == -color(i); (2) same open: open[i-1]-Equal_avg <= open[i] <= open[i-1]+Equal_avg; (3) long body: realbody(i) > BodyLong_avg; (4) belt hold: if i is white, lowershadow(i) < ShadowVeryShort_avg; if i is black, uppershadow(i) < ShadowVeryShort_avg.

Notes

A prior trend is not verified, nor that the pattern aligns with it.

Inputs
