I was looking for an Excel spreadsheet to calculate 13-column performance table and drawdown for emerging CTA. I found http://www.nfa.futures.org/compliance/samplePerformanceGuide.xls in NFA web-site. But it only has 9-column. Does any one have an Excel spreadsheet which can calculate 13-column performance table and drawdown? Or do you know where I may be able to get one? Thanks for advices.
