Di erent combinations of parameters and new ways to visualize data will be used. Results will highlight the importance of Ramex-Forum and its proper parameterizations for analyzing relevant relations among price variations in petroleum and other similar markets.engRamex-ForumFinancial data analysisPetroleum pricePetroleum production chainBusiness intelligencebook part10.1007/978-3-319-23485-4_58
