The Seventh Week: June 26 - June 30

The new market structure with the traders had been on hold for awhile, but during the seventh week, I finally got it running. The most interesting new part of this market was deciding how the traders would choose whether to buy or sell. There are obvious trivial cases - if they don't have any cash they can't buy, and if they don't have any units, they can't sell. For the case where a trader had the capacity to buy AND the capacity to sell, I decided to implement a decision process in which the trader considered his expected surplus for each action. If the difference between his buying price and his value of the good was higher than the difference between his selling price and his cost for the good, he would place a bid, and vice versa for asks. I hope to explore other decision making strategies for this situation, but as of the end of the seventh week, there were still some statistical computations to fix in this new market structure before I could move on.
