Great advice above to trade currency futures... not.
parabolic, you'll want to stay clear of FXCM, Gain and especially futures. Besides everything else, the minimum trade size -- 10,000 units for the former two, USD 53,000-83,000 and up for the latter -- is incompatible with both your account allocation to currencies and your self-described status as a newcomer to this asset class.
As a simple yet essential exercise, estimate both your maximum stop loss size, in pips / ticks, for an X% per-trade risk (you pick X) and minimum possible leverage, given minimum trade size of either 10,000 EUR/USD or, say, 1 E-mini Euro-FX. Feel free to post your 4 answers here. You may not use a spreadsheet or a calculator... if you can't do that in your head (or, at worst, on a piece of paper), you have no business trading forex.
If you pass this simple test (I am being dead serious), your choices at this time are limited to:
1) demo accounts;
2) those forex dealers (they are not brokers) with minimum trade size of 1,000 units or less. Of those, Oanda should be at the top of your short list and is superior to demo accounts for your purposes, including Oanda's own demo.
