Trip7 I checked out sharesight, looks like a great tracker. I researched DWR vs what I use (IRR) and their methodology should work just fine. There will be a slight difference in performance readouts side IRR takes into account the TIMING of the cash inflows and outflows, but it should be minuscule.
I will start tracking my trades in June. For me, it will be my 401k and Roth contributions. I do not intend to use this sight to track my derivative trades (options, futures etc).
Best of luck, may we both be more wealthy at the end of this :-)
