Providing the supporting detail would be your best bet. Here is a brief solution, and feel free to email me if you want to toss any ideas or ask any questions. For the record, I did pass the CPA a few years back, but am not a practicing CPA or accountant. So any opinions are gleaned from what I remember and what I can research. With that said.
If you had 25000 in your trading account on Jan 1 2001.
As of December 31, 2001 you had 75,000. Well assume you had a much better year than I

. You could Report that as 1 trade on Schedule D with a short them gain of let's say $48000. And I would list the asset description day trades.
If you had 2000 in interest income that would be reported on schedule B. Now comes the question of margin interest which is listed on schedule A. That (I may have to think through this) should be added back to the selling price of your trades and then deducted against investment income.
In the above example if your account Value at 31 dec was 75000, and you had 2000 in Margin interest, that would mean that you actually sold 2000$ more in securities and the broker deducted your margin interest from your account value, hence the adding back.
Hope this helps, off to the girlfriend's mom's for dinner

, but I may be back tonight or tomorrow depending on how dinner goes.
Have a safe holiday.
