I tried cointracking.info a couple of months back and figured that it would take some time for it to stablize. With different exhanges using different formats, and no support for all exchanges (at least the ones I am using), it is tough to tally. I finally used their export as basis and built my own excel sheet. I don’t think I have it all figured but I am happy with what I have. Now whenever I make any transaction, I add entries to my sheet.
