Usually TWS will reconnect very quickly without you noticing it. But recently I've begun to question just how reliable my ISP is. Its supposed to be one of the boutique ISPs for businesses. I've been listening to streaming music and occasionally, the stream is dropped. There have been 2 multi hour outages at the ISP this year- I suspect there were other much briefer outages as well.Quote from tt1452:
The biggest problem that I have encountered is my stand alone TWS dropping out and sometimes it takes several attempts to reconnect. (sometimes at a critical time).
Sometimes the internet as a whole can get congested and will drop a socket connection (between TWS and the IB server or between esignal and its data servers).
