slammedtgs:are you looking for a something from zecco, or a tax form? Im not sure what the 'realized gain/loss' statement is. Sorry, Im still new to this. Do you keep a record of all your trades, that should be enough to fill out your taxes.
I'm not positive, but I think that it's the 1099-B form for proceeds from broker or barter exchanges. The name isn't correct, but the form probably is.
I'm having that same sort of problem myself, going through trades and records isn't really that easy. It's easier if you don't do much trading, but it's kind of a pain if you're having to figure out where to put the gains and losses for short or long term investments without an appropriate form.
Probably the best thing to do is to call the brokerage that was supposed to send the form and check there. I know that TD Ameritrade and ETrade both do theirs electronically.
