Every day from time to time, my quotes freeze up in the excel DDE data feeds. NE1 Know what the problem might be? Sometimes, when I hit the refresh button the quotes go to 0, or worse, i receive quoting the wrong security/instrument. I wouldn't mind that much, but kills my conditional orders that I've programmed into the API. I would love to hear from NE1 that encountered and then overcame IB DDE data feed reliability problems . thanks
