I want to know that if i want to invest in commodity market, so can i get in physical form from commodity market and if i want to sell it another person except commodity market so can i do this.
In the commodities exchanges in India, you can trade the futures through your broker and can take delivery of the commodity. Only for some commodities, exchanges follow cash settlement basis similar to what happens in equity markets. You can read up contact specifications of the commodities on the Exchanges' website to know if it is cash or delivery settled. For instance, Chana's contract spec is here- http://www.ncdex.com/Downloads/ContractSpace/Chana_CS_09042012.pdf
You can sell the delivery taken from exchange outside or delivery taken from outside on exchange platform.
