The code presented here relates to the book chapter cited below. There are two implementations of the trading model algorithm:

1. code.java: This class is intended to give an overview of how the trading model algorithm functions. However, the focus lies not on the framework supporting the trading model. As a result, users are required to implement some of their own code in order to get the trading model running.

2. LimitOrders: A folder containing a fully functional version of the Alpha Engine utilizing limit orders.

Abstract

We introduce a new approach to algorithmic investment management that yields profitable automated trading strategies. This trading model design is the result of a path of investigation that was chosen nearly three decades ago. Back then, a paradigm change was proposed for the way time is defined in financial markets, based on intrinsic events. This definition lead to the uncovering of a large set of scaling laws. An additional guiding principle was found by embedding the trading model construction in an agent-base framework, inspired by the study of complex systems. This new approach to designing automated trading algorithms is a parsimonious method for building a new type of investment strategy that not only generates profits, but also provides liquidity to financial markets and does not have a priori restrictions on the amount of assets that are managed.
