Frankly speaking, I was confused about trading game especially with bidding price and how to calculate all these stuff. Now I guess I am getting in this process and it seems to be not so hard to understand. Moreover, maybe you don`t know but I am from Islamic country and things like trading games and bidding, gambling are strongly prohibited. However, I will bid even against my will because it is directly connected with my future grade (but I will bid once per week, in the day that mandatory). On my first week I did a big mistake, I wrote about my strategy and I thought that it was published but it did not. However, I fixed that problem today and the problem was my computer, virus.
My strategy
I think my strategy is partly similar to all students` strategies. The point of my strategy is the following, collect the data and information from expert groups, scan some websites and listen my intuition voice. One more important point is bid price at the end of a day, right before midnight. And always probe the demand curve for certain commodities. As long as did not make money I am not going to post a profit.
