It is true that Oanda is a nice online broker and having a nice trading platform. However, I have also come across some drawbacks of Oanda. They are having very long registration process, Leverage provided by them is of 1:50 with is too less as compared to other brokers. AVAFX and FINEXO are giving leverage of 1:200, deposit process takes time, they do not have the facility of credit card deposit, the main thing is the customer support, and they are having only chat only no phone facility. After seeing these disadvantages, I am not interested in going for Oanda.
First of all, let me say that I've been with OANDA for 2 years, and have never had a problem.
With registration, it took about 10 days or so to get completely set up, I don't know how long it takes with other brokers, but it didn't bother me too much, I wasn't that anxious to trade.
As far as credit cards are concerned, I wouldn't recommend financing your trading career with credit card debt. I sent in a check to fund my account, it took a few days.
Here's the deal with leverage: 200:1? you don't need that kind of leverage if you want to trade the right way. I risk no more than 1 % of my account on any given trade, sometimes half of that, sometimes even less than half of that, and I make decent returns on my trades and on my account overall (I trade long-term/swing, I don't day trade and maybe the larger positions taken while day-trading may require a little more leverage). BTW, I take multiple positions too, right now I have about 7 trades going, and a few others waiting to trigger. I can easily ramp up to 2% per trade if I wanted to, and still never have an issue with margin, even with multiple positions. Be very, very careful with leverage.
As far as customer service, they do have an 800 number you can call, and get service. I've only had to use them once, due to an internet outage that I had, and they were decent. I don't have enough experience with OANDA's customer service, however, to make an effective commentary about it.
That's my 2 cents on OANDA for what it's worth. I do not, however, have any experience with other brokers so I can't make the comparison.
There are lots of good brokers out there: I hear a lot of good things about Think or Swim and FXCM as well. Lots of choices.
Take care,
