what can i do to be a commodities trader?

Answer 1

Open an account with a brokerage firm that trades commodities. You will probably need to deposit at least $100k and in effect acknowledge (and perhaps show financial statements to prove), that you can lose it all and just smile about it.

If you mean that you want to be employed by a company as a trader, then you could look for a job with brokerage houses, agricultural firms, import/export companies, etc. Expect to start at the bottom (clerical work), and put it a lot of OT.
