I am an United States Citizen, my 2 children and fiancee are also U.S. citizens.
For the entire year of 2015 I will have lived in Mexico, about 2 hours from San Diego. I will pass the IRS's physical residence test and be able to take a 100k deduction on my income via the Foreign Income Tax Credit or I will use FEIE (Foreign Earned Income Exclusion)
So I trade stocks out of a United States TD Ameritrade cash account. Say I make $40,000 in short term gains for 2015 (I wish that were true, more like 4k for 2015).
How is this income treated, does the Foreign Income Tax Credit or FEIE reduce my tax liability against my United States cash stock trading account short term gains?
