I know nothing about trading bonds. Can anyone tell me if it would feasible to trade the spread between the two year, five year, and ten year treasury notes/bonds (I don't even remember what the difference is). I have noticed that the spread between the different terms seems to vary a little bit. Could these be traded as "pairs"? If any of you are familiar with this market, I hope you will forgive my ignorance and enlighten me a little bit. If this is a feasible strategy, what are the best instruments to use, and what type of broker would you use. Thanks for any help.
