Over the weekend, 1/10&11/09, the market figures ING used were incorrect. I made several trades that with the figures were $3, 000 buying and $1000 profit in sales of stocks. When they opened Monday and changed the figures, the stock that I sold were at a loss and the stock bought was $12, 000. I called customer service, they told me they were sorry and they gave me 2 free trades for my $12, 000 loss. Unless you like loosing money, don't trust any information on their quotes and they won't back anything up. They sent emails to confirm the problem and they knew about it at opening. They took no action to correct this or stop any transactions.
