Dear Tripack Dear DEF Thanks to both of you for your smart and useful posts. And thanks to IB for trying to improve their quote issue. Can you, Tripack please spend more words about your post? I do have eSignal as source of quotes I trade futures emini (NQM2 ESM2) Yes I do experience, expecially between 9:30 and 9:50 some occasional delays of IB quotes, even some freeziing... Using API I can create an execution tool like this: - I get Real realtime quotes from eSignal source - based on eSignal quotes, when my price-condition is met, my API tool generates (on IB TWS) an Order, say, (Limit or Market) Buy n ESM2 contracts. But will this order execute if IB quotes are lagging, say, 10 secs behind eSignal quotes? I guess YES if IB immediatly forward my order to Globex (Limit orders?) I guess NO if IB keep my order on its server, supposing its server sees the wrong lagging quote. (Stop Orders ?) Def what is your opinion? Tripack wrote: I agree with your points Catoosa. I too would like timely quotes. However IB has provided the tools necessary to circumvent this problem in the form of the ActiveX API. It would be feasible to create an order placing program that uses data from a different source and transmits orders via ActiveX. This is probably a bit of work but if it is costing you money you might be motivated to do this.
