straddles and strangles

[McMathews]

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.
Regards
