thanks for the illustration. however my question was pertaining to futuresources option quotes and other sites that put multiple zeros and decimals in front of the price making it difficult to calculate. they always show zeros and decimals in front of the option premium prices. in particular, i like using futuresource because they have the option quotes for all the futures and puts and calls in one table rather than have to go to diffrent websites for the individual exchanges. also, many quote services also put those decimals and zeros in front of the price and its real confusing. when you get the chance check out http://www.futuresource.com/quotes/options.jsp?s=SIK07&r=SI the silver options i am talking about are the regular 5000 oz comex silver options. as of the close of 3/26 the may 15.25 calls are selling at a premium of "0.020". so how would i calculate a number like that to figure out the cost of this option? if you can also check out http://www.futuresource.com/quotes/options.jsp?s=JYM07&r=JY the may 8750 japanese yen futures calls are selling as of the close of 3/26 at a premium of "0.00330" how would i calculate the value of that one? the zeros and decimals are confusing. let me know if you can figure it out. thanks.
