Hello! I have been investigating to trade a basket of interest rate futures in the US, amongst others, Eurodollar Interest Rate, 10 Yr Treasury Notes, 5 Yr Treasury Notes, US Treasury Bonds and 2 Yr Treasury Notes. However, it was suggested to me that 30 Day Federal Funds are also "actively traded and liquid". But when I looked at the volumes on the CME website, it appears that the volume is quite low. Am I reading this correctly? Is there something I am missing? Thanks for the help!
