Hoping someone can shed some light on the 2 tax forms for futures traders. IB does a good job with IRC Section 1256 summarizing all futures transactions. But I'm not clear on how they get the amounts for box 8 and 11 on Form 1099-B or why a 1099-B is even needed for futures traders. It doesn't correlate with any amount I can find, or maybe it's just late and I should go to sleep. Anyone know?
