The article explores how traders in a market make decisions based on past prices to predict future ones. They found that in a market with many different types of traders, there are two main types of equilibria: one where a single trader dominates, and another where many traders hold a share of the wealth. Regardless of the number of traders or their strategies, all equilibria fall on a one-dimensional line. The study also discusses the performance of different trading strategies and how the market dynamics are influenced.
