Shorting and Long volumes for a future

[berryberry]

Hello All,

I am trying to understand how to know what is the shorting volume and how much is 'longing' volume in a future. In other words, for a particular future, how much trading has been done shorting and what is the volume of lots that people have bought?

Please let me know where I could get this data on a daily basis.

Thanks in advance
