I am thinking of signing up for this service. I am very interested in mechanical trading systems & would like access to both historical EOD & intraday data for back-testing while also being able to access a live-feed via third-party apps for day-trading purposes. My Question: would I be able to access all this with just the eSignal Basic sub.? eSignals on-line help initially told me I would, until I asked about their exclusion of the 'Pick & Mix' addition from the Basic Sub. (I'm still not sure what this is!) - I was then told that historical data was not included!! I'm with Ameritrade Apex at the moment which is almost perfect (imo!) but not quite - there's not way for third-party apps to access the RT feed. Also, exporting historical data is limited to 1 year of EOD info. Almost every trading application I have come across accepts data form eSignal which to me is a big plus so it seems like the way to go. Any information would be appreciated.
