I need to be able to look more at option spread graphs. Optionstar has IB data feed which I want to use. I am used to using Openoffice calc but it does not have Excel style data import. I am having trouble using Excel 2013 which I think is much different from Excel 2010. When I try to run just the free Optionstar EZ, the macros will not run because Excel says a password is needed. Does anyone know how to get Optionstar to run with Excel 2013? I do not think I can buy an earlier version of Excel.
