The financial market has presented significant growth in the automation of decisions and execution of strategies that can achieve good returns from investments. Consequently, the need for an increasingly robust and reliable environment, allowing to analyze different investment strategies, has increased. Based on this need, this work presents A Multi-Agent System Framework For Automated Stock Exchange Simulation (FrAMEX), which allows the creation of different simulators for the financial market based on the paradigm of software agents. Intraday and interday simulators created from FrAMEx are presented in the document. Besides the analysis of different investment strategies used in such environments and executed by agents run from investors. Since these agents achieved good performances in their executions, they participated in two versions of the MASSES competition. Thus, the description of the performance of each agent developed is also presented.
