I am trying to figure out what is causing this and I was wondering if anyone has been experiencing the same problem. I am based in central London and have been with IB for years. I love IB and never had any problems with IB's data feed until recently. However, since 6 September 2010 my streaming quotes in TWS regularly start to freeze up intermittently for 2-10 seconds every few seconds or so from about 7:05pm UK time (2:05pm ET) until the US market close. This happens with US stocks, US futures and US and European futures data after 7:05pm every single day. I run standalone TWS software all day and have absolutely no problem with streaming quotes at any other time of day or night, until 7:05pm. I also run streaming video at 200 kbs (Bloomberg TV and CNBC) at the same time and this is not affected, ie I have no interruption on streaming video after 7:05pm, nor is there a change in my DSL line connection speed, which I have tested on different speedtesting websites numerous times. I have had the same 8Mbs BT Broadband DSL service for three years and have never had any problems with the service. I don't know what to make of this. Has anyone based in the UK or anywhere else experienced the same problem? Any ideas or suggestions greatly appreciated.
