if you want to get to meet an IRS agent firsthand just put "Trader" on your tax return.
No doubt one will trade a whole lot better if there not worried about making mortgage or insurance or the kids tuition expense.
My investment account has 2 main positions in it which very likely won't change for several years: long UUP -- the dollar index -- and long DTYS -- short 10's i.e. long yield.
Shorter-term trading gives me peace of mind when I know the stats on the method I trade ahead of time. BUT, that does not mean a financial meteor can't streak across over the horizon and take out any given broker where I happen to have an account. My like style would not change a wink if that were to occur. I would be pissed though.
