I have subscribed IQFeed for nearly 3 months, the big connection issues is here:
IQFeed Data connection did not works in China and the connection drop repeatted and IQFeed frequently automatically logout with an error message " Sorry, your Product and/or Service for the attempted login are incorrect. If you have recently changed products you may also need to change your type of service. Please contact DTN customer support for assistance. (1)" Then IQFeed will automatically close in about 15 seconds. After that, IQfeed process is dead, and automatically reconnect will failed. So i must terminate the previous IQfeed process and restart it. please refer to the attached screenshot. I tried and tested on the two main ISP in China, China Telecom and China Unicom. China Telecom seems a little more stable than China Unicom. But the result is same. I also tried on my two worksations , there are same error result. So i think there is a connection problem on IQFeed connection from Shanghai, China to US server. Then I start to run IQfeed on VPN connection, it became more stable than direct conneciton. but there will be some connection drop too. As you guys may know China Great Firewall aways disrupt VPN connection, that means VPN connection is not stable. But at least, there are less drop when IQFeed running on VPN connection. I have report this issue through live chat, but it looks there are few users in China so there is no good solution. If any guys here have such similar problems and know any solution please let me know. Thanks Aaron File Attached: iqfeederror.PNG (downloaded 770 times) |

Hi Aaron, the "sorry, your product and/or service for the attempted login are incorrect" is not typically associated with a bad connection. While a connection problem can trigger it, more often it means that there is a problem communicating with an application/software, i.e. either the software is unsupported or there is a process hangup between the two products.
It's certainly possible that you have an internet connectivity problem that is outside the scope of IQFeed support. However, you may also want to reach out to us again in chat so that we can get more details from you, to determine if something else is happening here.
