COMMODITY TRADING

It's an age-old phenomenon. Modern markets came up in the late 18th century, when farming began to be modernised. Though the trade's mechanisms have changed, the basics are still the same.
In common parlance, commodities means all types of products. However, the Foreign Currency Regulation Act (FCRA) defines them as 'every kind of movable property other than actionable claims, money and securities.'
Commodity trading is nothing but trading in commodity spot and derivatives (futures). If you are keen on taking a buy or sell position based on the future performance of agricultural commodities or commodities like gold, silver, metals, or crude, then you could do so by trading in commodity derivatives.
Commodity derivatives are traded on the National Commodity and Derivative Exchange (NCDEX) and the Multi-Commodity Exchange (MCX). Gold, silver, agri-commodities including grains, pulses, spices, oils and oilseeds, mentha oil, metals and crude are some of the commodities that these exchanges deal in.
Trading in commodities futures is quite similar to equity futures trading. You could take a long position (where you buy a contract) or a short position (where you sell it). Simply speaking, like in equity and other markets, if you think prices are on their way up, you take a long position and when prices are headed south you opt for a short position.
