I have just downloaded the donationware Hyperserver Lite to update the IB datafeed into Tradestation from http://www.hypertrader.it/htools.shtml . I see that the program uses DDE to get data from IB. Is DDE relaible enough for trading? I had problems getting more than 20 sysmbols to update in www.neoticker.com . www.sierrachart.com uses the IB api and was reliable but I would like to use Tradestation. Does anybody use DDE to trade? How does metaserver for IB compare? does it use DDE as well? thanks for any help and your opinions.
