I propose you to observe the process of my next option combination conducting.
Size of investment for one combination is 50,000$. For purchase straddle i put no more than 2/3 total amount of investment. The remained sum is necessary for management of a combination. Today i opened long straddle of OXY (Occidental Petroleum Corporation). It has been bought 46 contracts of OCTOBER’12 90 CALL (2.69$) and 46 contracts of OCTOBER’12 90 PUT (4.41$). In purchase it has been spent: 9.45*100*46=$32,660. Further i will conduct the combination.
