Three Black Crows
By LuxAlgoJun 8, 2026
Three Black Crows is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
Three Black Crows enforces every qualification the tradition attaches to its three-candle decline, the first faithful detector of three black crows here. Each crow must print a long dark body against the pre-pattern average, close near its own low, and open inside the prior crow's body, with closes stepping lower after a confirmed advance. Patterns are boxed and labeled.
How to Trade the Three Black Crows?
- Pattern label: an advance met by three qualified crows, one of the stricter entries in the candlestick reversal catalog.
- Identical Three Crows: each crow opened at or near the prior close, the rarer, traditionally more bearish variant, labeled separately.
- Structure break: a third crow closing below the last confirmed swing low is annotated and alerted.
- Bounce levels: dashed lines at the pattern midpoint and first crow's open mark where many traders wait to sell a bounce instead of shorting the stretched third close; each dims once touched.
