比如：oanda的网站和交易软件有中文吗？受那个国家监管？对3-5分钟内的交易视为拨头皮吗？信誉如何？

没有中文.美国监管.一般不会,赚了大钱会不会不知道.信誉中上.

哦感谢象汇兄 没有中文，没法交流啊！也难开户呀

有美国那啥认证么？

有NFA认证 OANDA is registered with the U.S. Commodity Futures Trading Commission (CFTC) as a Futures Commission Merchant (FCM), and OANDA is a member of the National Futures Association (NFA # 0325821). These organizations impose rules and regulations on FCMs specifically to protect the customer funds. 见http://fxtrade.oanda.com/fxtrade/funds/fund_safety.shtml
