CDLGRAVESTONEDOJI

Summary

Single-candle doji whose open and close sit at the low of the day, leaving a long upper shadow and no lower shadow. A doji variant whose bullish/bearish meaning depends on the surrounding trend, which the code does not judge. A hit marks a gravestone doji; its bullish vs bearish reversal meaning must be read against the prevailing trend, which this function does not check.

Formula

One candle. Detected when all hold: (1) doji body: realbody |close-open| <= BodyDoji average; (2) very short/absent lower shadow: lowerShadow < ShadowVeryShort average; (3) non-short upper shadow: upperShadow > ShadowVeryShort average (open/close at the low with an upper shadow).

Notes

Does not verify the prior trend that determines the pattern's bullish/bearish meaning.

Inputs
