A robust market is not just judged by the availability of trading products and a regulatory mechanism but also by the quality of participants in the market. The same is the case with commodity futures market too. While there are thousands of traders who are trading in and out of various precious metals, industrial metals and agricultural commodities, these traders and participants can be broadly classified into four broad categories. This classification is very important as each of these categories of participants has a unique imprint on the market and contributes to the robustness of the market in their own way.
