Quote from stock777:
Yes, I did see a refrerence in the IRS instructions saying to break out the mtm trades.
Another question, my interpretation of the IRS code leads me to report stock mtm trades on 4797, and not flow any of that gain to the Sched C. There are many suggestions on the web to somehow move that amount to the Sched C, so that it 'looks' better when reporting expenses there, but I have not been doing that, leaving the gain on 4797, and flowing to 1040 line 14.
Are any of you doing this, or something different?
