CDLDOJISTAR

Summary

A two-candle reversal pattern: a long real body followed by a doji whose real body gaps away from it (up after a white body, down after a black body). Signals a potential reversal of the prevailing trend. A hit flags a likely trend reversal; true direction depends on the prevailing trend (bullish in a downtrend, bearish in an uptrend), which the code does not itself verify.

Formula

Two candles. Candle 1: long real body (realbody > BodyLong average). Candle 2: doji (realbody <= BodyDoji average). Gap: either candle 1 white (color1) AND candle 2 real body gaps up above it (the real bodies gap up), or candle 1 black (color-1) AND candle 2 real body gaps down below it (the real bodies gap down).

Notes

Does not verify the prior trend the reversal signal classically assumes.
