Corn
Corn is a crop widely used in the food industry for producing flour, corn flakes, and so on. Corn is also used to make paper, fertilizers, construction materials, packaging materials, plastics and other synthetic materials. It is one of the most important feed crops. Overall, corn is the third most produced crop in the world, after rice and wheat.
Corn is usually delivered in December, March, May, July, and September. Delivery time influences the contract liquidity: the closer the expiry date, the greater the liquidity. However, a few days before expiration the liquidity drops down drastically.
Corn prices depend very much on the season: as a rule, they are very low during the harvesting period, but do increase at the sowing season when the uncertainty regarding future harvest, are growing.
For day trading, the most interesting timeframe is between 4:30 PM and 7:15 PM GMT, when both liquidity and volatility increase.
