Quote from RockMachine:
When I asked them a while back the fella said it was simple..."Just give it to your accountant" = comforting..
Take 2010 statement end balance - begin balance
Net out deposits and withdrawls
then subtract 1099 (reported) transactions = Forex
I believe that option transactions might not be accounted for
on 1099 as well (check that) if so you need to account for that
separately.
That same statement 2010 you can also figure out your
int. earned and paid as well as commissions in USD which I
assume is your account denomination.
