Am a real novice at this; but can someone help me with a couple of queries:

On Pinnacle they have (besides the obvious and indicated symbols) one that is like + sign in a litle box. Meaning?

Several sites give the odds in decimal format with + and - signs e.g. Ancic/Capdeville -234 +294. How do you convert this to dollar pricing?

Oh, and one thing more, are any of the matches broadcast on radio?

Any help appreciated.
