Spyders, Diamonds, and what else?

[Ketayun <ketayun@xxxxxxxxxxx>]

We have just discovered :-)) the existence of spyders and Diamonds. First
would someone be kind enough to give us the symbols for these, Second,
what is QQQ, third, is there an equivalent for trading either the Nasdaq
100, or MSH index? Any site that discusses how to trade these?
Thanks a lot.
