#1-you must monitor the ES or YM (SP500 and DOW) as it moves in opposite correlation to it. The ES, YM will help "fire off" signals to trading the 5,10,30 yrs. #2-you will need to trade more than 1 contract to make real money. 2,3,4-10 or more contracts. Especially if trading the 5yr note. Trading 1 contract just does not have the movement needed...if so, only the 30yr has the movement perhaps per 1 contract. #3-less contracts are more of a "swing trade" and not "scalping" or "high frequency trading"
