I'm backtesting futures data and found some softs tradebar data are almost none.

For the test, I modify all weather portfolio project consist of only softs data. (sugar #11, cotton #2, coffee). 

There is no trade or whatsoever. Is it supposed to be like this?

And found some metals are also a little incomplete (starts from 2011~; other assets in futures start 2009.)

Thanks you in advance.
