Hi Tom, I trade with oanda and apart from a few glitches with there app updates on the android phone I have had no problems as of yet so not sure I follow??
Oanda is a MM with NDD.. I've used them in the past. Their spreads are lousy, unusable for a day trader. But they have 3 levels of security (username, password, codes ) and that's good, not very common among brokers.
