Hi all
It is said that straddles and strangles are two effective trading strategies. How effective are these strategies. Can both be applicable while stock prices are galloping upward or decreasing? I am searching for details of this strategies and how can they be developed and implemented.

suggestion...to be helpful
learn some more about options - there are many sites.
Then ask again, as your question is too broad to make sense....just saying - straddles and strangles are not strategies. They are option jargon - like jelly rolls, collars, and ratios.

are you looking to go long or short the straddles and strangles?
are you buying/selling them because you think there is a big move coming, or no move?
there are many variations with regards choices of strikes, months, skews before looking to implement options into a strategy.
Of course just blindly buying or selling might work also
