This is probably a really stupid question... But I'm new to options, I plan on reading up before I start trading but if you look at FXCM, A Buy open call Aug 21st 2015 I can choose a strike price of 1.0 at 1.4 ask 2.5 at .6 ask 4.0 at .3 ask So why would anybody buy anything other then a strike price of 1?
