Under Global Configuration...General...eSignal, it asks whether I want to use eSignal for Market Data -- a rep told me that that's an alternative data provider (requiring separate paid subscription). Rep said that it would be the data provider for both data in TWS *and* what gets streamed into Excel via API. I just want to know what the pros/cons are of using eSignal for market data, since a Google search turned up remarkably little info. I have performance issues with TWS + Excel (since I'm streaming in several hundred contracts simultaneously), and want to know if eSignal will be substantially faster / more reliable, etc. Anyone here use eSignal?
I've used eSignal before. It's a charting package and you need to run their client in order to get the data, even to stream data into other applications. I could be wrong, but don't think they've changed their policy on this. https://www.esignal.com/compare-products They clean their data and provide many markets, but you'd need to investigate deeper to see if it fits your needs.
%% Better than average; + sure better than YHOO, mountain dew. I lost e signal intraday once/seldom; but 20 day chart worked well so NO need to close a position fast, dorian...........................................................................................
