The shooting star candle comes after a bullish trend and the long shadow is located at the upper end.

When finding these patterns, traders should look for a shorter price reversal, rather than a longer one as longer reversals can give false signals.

After breaking the neckline and the main trend line, the downward trend is fully established.
