Hello Evelyn,
If you are from the United States (can't tell, perhaps the "Hallo" is an accent
), then EasyForex probably isn't an option for you at this time. I had tried to sign up with their affiliate SimpleForex and EasyForex and neither would work for me.
Oanda I still have a few dollars in my account there, but really don't like the trading platform - I personally found it harder than systems using MT4 or other platforms. They do have lower spreads but lower leverage as well if that is important to you. You can fund an account with a very small amount of money, they say any amount even a dollar. Can't complain on getting my money in and out other than a bit of a fee on the Paypal payment perhaps I would put more in at a time to water that down if I go back to them. If you think you might use them definately check out the demo version FX Game first and see if you like the way they work before funding a live account. I do plan on playing with the little bit of money I have left, perhaps if I use a different platform to chart.
I haven't used the others mentioned. Best to you.
