I'm mostly interested in tracking NAV of my portfolio, and will update it weekly or monthly.
Also, I'm considering starting a trade diary on the forum. Are there others doing the same, would like to see where to post it and what to do - and perhaps more importantly, what not to do and show.
I'm using this Account Tracker v1.10- Public it has no API or any external link/macro. You have to fill the data by yourself.
Found it quite useful, I thought I was up $100, and after filling it found out I was actually down $50. But it is google spreadsheet. I think you can export to excel with no problem.
