why would you try to mimic "esignal's" service, they are not all that great... overpriced for the charting and for their market data... in any event, define "mimic"... it is not clear what you are trying to accomplish...
Sorry I should have been clearer. I have certain charting/scripting tools that only work with eSignal data feed. I don't want to subscribe to eSignal for the obvious reasons. so I am looking for an application that will act as a eSignal emulator so that the said applications could connect to it. I get my data from free sources through DDE. Also I have several years of historical intraday data.
