Day trading strategies for short positions

[GoldWTcal 1]

A lot of day trading strategies are basically for going long positions. Such as Bull Flag, ABCD, etc.

A question for those experienced traders:

When you go short for a stock, what strategy do you usually use? ( the most often used one ).

Can you please share tips like: 

1) why do you pick this strategy as the favorite for going short - what are the reasons behind when there are other strategies available. 

2)  the pros and cons 

 

Thank you,
