RE:Trading@ kona55 - You may want to review the paperwork on your trading account. Your platform may be kicking out your buy orders because of the 2 day settlement period regulation. In other words, the funds from a stock sale don't register in your trading account for 2 days and if you're up against your cash balance or margin limit, the platform kicks out your buy order on the basis of insufficient funds - even though sufficient funding isn't the reason that the platform rejects the buy order.. So after rejecting the buy order, the platform tells you to phone the trading desk to verify sufficient funding in the account for the new trade.
The trading desk may be able to modify your platform settings and remedy your situation depending on your trading history with them and the type of trading account being used. Don't quote me on it but if the trading desk can authorize trades that have been kicked off of the platform, then they can modify the platform settings on your account to permit those trades too.
As LL points out though, "wait times are currently longer than expected." "Please hold."
Then after holding for half an hour you have to hope that the person on the other end of the line knows something. It's not always the case.
