Final answer:
The 'shooting star' is a candlestick pattern in stock trading where the upper shadow is 'longer than the body', indicating a potential bearish market reversal.
Step-by-step explanation:
The question is concerning a specific pattern observed in the context of stock trading, known as the shooting star candlestick formation. This pattern is used in technical analysis to predict potential market reversals. The shooting star formation typically has a small real body with a long upper shadow and little or no lower shadow. Thus, the correct answer to the question 'The shadow of the shooting star formation should be?' is (b) Longer than the body.
A shooting star is a bearish reversal pattern that occurs after an uptrend, indicating that the price may start falling. It resembles an inverted hammer but is formed in an uptrend. It's characterized by a small lower body, and a long upper wick indicates that the buyers tried to push the price up, but the sellers prevailed and pushed the price back down near the opening value.
