one day i wake up, found the soybean market was falling apart, i quickly closed those contracts. result loss for the first three contracts.
then the following 3 long contracts were due to system error. i transacted three contrac without my order. 
then, i went long on wheat, but it turn out delcining, to stop loss, i closed them,
another three short soybean contracts, again, system error.
and this is pretty much the story.

The road ahead (week8)
Last week is a big mess. I lost several thousand because of delayed action. And the system has gone long for me, when the market was lashing and goes short for me at the market lowest price ever.
Soybean has decreased from 1500 plus to below 1400. The reason for this is goldman( a fund was disposing their holding of long contracts. Also, estimate of yield was higher than expected for 3%.
In the previous blog I noticed that there might be disposing of funds, which happened last year. I thought it was a valuable information but since of the time constrain I didn’t dig it deep. And the market before disposing can be quiet confusing: the price would not fluctuate as usual, keep stable for several days and began to slump.
I got the lesson as well as some inspiration of long term operation. Every summer the price of soybean and corn will reach to the peak price. It would be a good choice to hold short position when the price is high until mid of December.

3. Risks Associated With Investing Directly or Indirectly in Corn http://teucrium.com/component/content/article/81
A comprehensive introduce of the riskes in corn market. Whoever is operating in the market is worth to take a glance.
Recently, I haven’t done too much on gathering information and fundamental analysis, basically is technical analysis and that’s it. Since we are trading in a extremely short time horizon, demand and supply can be easily influence by information shock plus we, as students, don’t have much time and first hand information source, the best approach for us is to do some technical analysis.
Here I share a little trick with everyone. First, set a expected high price and low price for your commodity. Second, get up early in the morning, check the price. If it is higher than high price, go short; lower that low price, go long. (Combine with price trends in recent days).
There is some logic behind! Supply and demand in soybean and corn are relatively stable, given no huge drought, flood or export restriction. Price is basically influenced by information which will make the price fluctuate in a quiet stable pattern. If price is not falling as you expected, don’t worry, it will sure get to there.
Set the expected price limit is quiet easy; all you should have is to study the pattern of price. As long as they are not too absurd, we will make money.
Last time, I found that one article mentioned that corn contracts are largely held by funds, investor should be aware of the funds in case they get rid of the corn in a sudden. Also, I noticed that Mark has large amount of unrealized gain which is the result of long time holding. Base on the two points above, I decide to go short with corn by long term approach. At the same time, continue with my little trick.
Cheers everyone
Good luck with all of us!
Basically, nothing went wrong this week, really good luck.
Because of the hurrican and earthquake, i didn’t enter market untill wensday. i found the prices were up like $10 plus on both corn and soybean. Hence, i went short on soybean for 3 contracts and corn for 2 contracs. However, on the rest of the wensday, price of these two commodities keep on rising, then i got 2 more short contract on soybean on the next morning. And close the contracts on friday. 
Price keep on downward sliding on friday. closed them and get some money.
