need some education on where to purchase puts and calls in relation to where you think the market is going. let's say i think the gold market is going up to $2200 by the end of August. currently there is a June contract trading around 1992, an august contract trading at 1997 and an October currently at 2010. 


if you wanted to buy a call to participate in your predicted rally, where would you be looking? and at what strike price? i don't know if it makes more since to buy at your 2200 predicted price or say halfway at your 2100 price? I'm not familiar with the Greeks when it comes to options as you can tell. 

I appreciate any education
