Quote from aqtrader:
I had a login problem this morning before the market open. I called MBTrading. The told me to update my password and waited 10 minutes. I did so. After 10 minutes at around 9:35AM ET, it was still failed to log in. Then, I called them again. They said they server was down and would take sometime to recover. It came back about 20 minutes later. Everything was fine except their quot server was very slow all the day. And also the current position list did not update P&L promptly.
I have been with MBTrading for over 3 years now. Only a few days they had a few major issues like this. Their software (MB Navigator) is not the best, but is ok to me.
