I´m also opening an acct with OANDA. My main reason is to hedge my USD acct I´m opening with another broker.
Let me explain. I live in Europe so my main currency is Euro. The new broker I´m opening an acct with, doesn´t allow me to keep my acct in Euo´s. If I open an acct with lets say $35000,- in it, I can now enter a stop order with OANDA to SELL $35000,- for Euro´s so in case the Euro keeps rising I don´t lose money by having a USD acct.
I investigated OANDA as good as I could and couldn´t find anything negative about them except the registration (Which has been done by now)
Also, a close friend and trader has an acct with them for a while now and he has withdrawn money several times.
Hopes this helps.
