Commodity

Commodity markets can include physical trading and derivatives trading using spot prices, forwards, futures, and options on futures. Farmers have used a simple form of derivative trading in the commodity market for centuries for price risk management.

same thing as future.. u need not to take delivery .. its not compulsory dear

I must suggest... Stay away from this....  its not an high return with minimum risk earning option dear....

This is just a short cut.. and u better know how short cut came to an end soon........
