Read up as much as you can. Use all sorts of mediums. Forums, books, stare at the screen for hours.
Trading has a time stamp on it. Usually around 3 to 4 years before you understand what you are doing. After that many traders have a few career options
1. Trade their own money, if they have around $250k set aside spare (rarity on the retail side).
2. Trade other people's money. Set up a hedge fund. If one is good enough, perhaps a regulated hedge fund can hire you.
3. Enter market making (brokerage).
4. Setup signal service, promotional websites.
If you are planning to do it professionally for $5k to $10k deposit, I would recommend you stop now, and look for a different career option. It has never happened in real life. At least there is no documented proof of one.
As for the carry trade, a quite popular one now days is the USDJPY on the buy side. Japan is going crazy with printing money. Virtually zero cost to borrow the yen, and buy USD or any high interest rate paying currency. Many hedge funds have this trade running, since the printing presses in Japan were installed with nitrous oxide.
Carry trades work only if your direction also works in tandem with the interest rate earnings. If you are losing money on the direction, then interest rate earning won't matter.
In any case, you look like a very newbie person, to be even talking about entering the trades for real. Demo your skills, and then wet your feet later on.
