last week i had a expectation that corn and soybean will slump down in this week. it turns out that though they didn’t slide down largely, but still decline a lot.
At the first two days, both of these two commodity went up quiet a lot ( their price already high). Hence I entered into the market at corn’s highest price ready to go short. ( i am not sure about soybean, had no gut feeling on that) 
finally, at the end of this week, corn price falls from 765 to 738. I closes the transaction at a relatively low price and gain a little.
Though the price is still decreasing, I am not greedy. That’s what i went right this week.
