I have two machines I use to connect to IQFeed. They always seem to be 'sticky about which IP they connect too and both act differently. One always seems to connect to and I get good historical data. The other seems 'sticky' on and I consistently get messages '!ERROR! Invalid symbol.' A test symbol that gives this error is 'SPX.XO'. The registry settings on both machines appear to be the same and I can not find where the sticky IP comes from. They are both running

So two questions:
1. Why am I getting these invalid symbols on *.150 and not *.116?
2. How can I change the IP I connect to?

BTW, I do not use the feed on both computers at the same time.

simon, you can not specify which server you connect to. However, there are ways to change which server farm you connect to. We do not recommend this because they bypass load balancing and would cause you to not connect if the server farm you are pointing to went down for whatever reason. is the server IP address for our Pre-Production server farm. I suspect that at some point you were testing out some new features from that computer and switched your hosts file to point to that server and forgot to change it back. In order to resolve this, you will want to open up your hosts file and remove the line directing login.interquote.com to Your hosts file is usually located in the C:\Windows\System32\drivers\etc\

If you are unsure about the process or cannot find the file, please contact our support department for assistance.

That is exactly what happened (I was having the issue on my development machine). I modified the hosts file and volia. I had forgotten about that.

Thanks again!
