I subscribe to eSignal to get real-time Hang Seng Index Option prices. Since day one, the data has been wrong as the prices alternate between sudden plunges and normal market prices. I reported this problem to eSignal 2 months ago. Initially, the technical support said the problem was fixed. It was only when I found the problem still persisted that they said they would release a fix half a month later. Finally, the real-time market prices have been suspended altogether after the release of the fix. I reported the problem again and the technical did not got back to me. This is something very basic and yet the problem has not been resolved after 2 months. It is totally unbelievable such a world renowned data provide would provide such disappointing and frustrating service. Do you know what I can do in this case to have eSignal handle this problem? Thanks.
