Anybody knows how to report the day trading ordinary gains and losses on Part II of Form 4797, Sales of Business Property if elected section 475(f) Mark to Market? IRS Topic No. 429 says use form 4797 Part II. There is a table on line10 of Part II to include gains and losses. If there are hundreds of trades, should list them one by one or just put a total? If list one by one, how to handle hundreds of trades? Also, does it only need to fill out line 10 to 18 and leave rest emply if only report ordinary gains and losses?
