I just tell them how much I started with and ended with. No way am I going to tell them exactly what happened in each trade. I probably made over 1000 trades.... lol
Joe just saw your question on taxes. I have this link, answers a lot of questions. If your making serious money want to try to do the 1256 60/40 split, however it does require specific record keeping they say, this article explains it, ton of FX tax info on this site, In my reading online it seems FX is still a grey area for the IRS, since spot trading of FX has become popular they have not laid down specific rulings.
