This is not an audited document. I don’t spend enough time correcting rounding errors, calculating exchange fees, NFA fees, or others. I know that over time they may add up. I try to keep the difference between the stated account balance from my broker (which I update with each blog entry) and the totals from my blotter. If you see other glaring inconsistencies, let me know. I’ll try to fix them. Read this post if you want to understand the purpose of a blotter.
