Soybean is a crop used widely in food production. Soybean products popularity has been growing usually recent years, which boosts the demand.
Soybean is delivered in January, March, May, July, August, September, and November. While the expiration is approaching, the contract liquidity grows, but a few days before expiration the liquidity drops down drastically.
Soybean prices depend very much on the season: as a rule, they grow right before the sowing season starts and go on rising up to the moment the sowing season ends. This is the time the prices reach their highs. After that, the prices start dropping, unless natural disasters occur which influence the future harvest.
For day trading, the most interesting timeframe is between 4:30 PM and 7:15 PM GMT, when both liquidity and volatility increase.
