The first candlestick having a black, real body, and the second has a long, white, real body. The white day opens sharply lower, under the low of the prior black day. These candlestick formations consist of a small real body that gaps away from the real body preceding it. The real body of the star should not overlap the prior real body. The color of the star is not too important, and they can occur at either tops or bottoms.
Stars are the equivalent of gaps on standard bar charts.
The formation is comprised of 3 candlesticks. The third candlestick is a white real body that moves well into the first period's black real body. This is similar to an island pattern on standard bar charts. Three candlesticks compose the evening star, the first being long and white. The second forms a star, followed by the third, which has a black real body that moves sharply into the first white candlestick.
