Typing 20 numbers once a month doesn't seem like a whole lot of work. If you are concerned about errors, type them in twice and take the difference in Excel -- if you get any non-zero differences, then look for a typo in that account. Yes, I'm sure you can automate things using IB's flexible statements.
www.hedgefacts.com has a good suite and will only take a few BP for their efforts. If you are a CTA and only manage managed accounts, what would be the pros and cons of using (1) Web-based administrator (such as hedgefacts.com, etc) vs. (2) The standalone software package (such as DMAXX.com, etc)?
Most people would probably use Excel. It looks like some people already use Excel!! Can any one advise me where I may be able to get a sample Excel spreadsheet to calculate CTA performance table? Thanks.
