Ramex-Forum: a tool for displaying and analysing complex sequential patterns of financial products.

Financial data provides a valuable up-to-date knowledge of the world economy. However, it is presented in extremely large data volumes, in diverse formats, and is constantly being updated at a high speed. The Ramex-Forum algorithm is oriented to guide financial experts in finding new and relevant information. We present a sensitivity analysis and new visualizations using an improved version of the Ramex-Forum algorithm. The proposed algorithm is applied to two case studies - the petroleum production chain and the European financial institutions risk analysis. Different combinations of parameters and new ways to visualize data are used. Results highlight the importance of Ramex-Forum for analysing relevant relationships in price variations in financial markets. [ABSTRACT FROM AUTHOR]
