What it is
A shooting star is a single candle appearing after an advance, with a small real body near the low of the range, an upper shadow at least twice the length of the body, and little or no lower shadow. It records a session in which buyers pushed price substantially higher and then lost the whole gain by the close.
How it works
The identical shape after a decline is called an inverted hammer and is read as a potential bullish reversal, so the preceding trend is again part of the definition rather than background. A shooting star is more meaningful when the upper wick pierces a known resistance level or a prior swing high before failing, because that combines the rejection with a failed breakout.
How traders use it
The usual approach is to wait for a lower close on the following candle, enter below the shooting star, and place the stop above its high. That high is a clean invalidation point: reclaiming it means the rejection was absorbed and the read was wrong. In practice the pattern is used at least as often to tighten stops or take partial profits on existing longs as it is to initiate a short.
Where it breaks down
Isolated wick patterns lose meaning on very short intervals, where a single sweep produces the shape many times a day. Frequency is also asymmetric: markets that grind higher and drop quickly produce plenty of shooting stars that lead nowhere. As always, the candle earns attention only where price already mattered.
