yeah, I have crude oil futures displaying on my iPhone stock app.
This is how it works...
Crude Oil is CL
Then there is a month indicator.
Jan = F
Feb = G
Mar = H
Apr = J
May = K
Jun = M
Jul = N
Aug = Q
Sep = U
Oct = V
Nov = X
Dec = Z
Then the two digit year.
Soooo the crude oil selling right now is CLV08 for October delivery
The iPhone will find it, but you have to tell it what exchange you're looking in, and Crude trades on NYMEX....
SO simply plug this in - CLV08.NYM and that's it. At the end of the month, you delete that one, and plug in CLX08.NYM for November.
As far as the other ones, they work the same way, but don't know their symbols, so I'll leave you and google to figure that out.
