IRS says ...
How much can I earn and still get SS benefits?
If you are under full retirement age for the entire year, we deduct $1 from your benefit payments for every $2 you earn above the annual limit. For 2015, that limit is $15,720. Beginning with the month you reach full retirement age, your earnings no longer reduce your benefits, no matter how much you earn.
I'm guessing from age 62 - 67 if you continue trading, you don't take SS early?
