Unless something has changed recently, I believe you can get 8 days of tick data from IQFeed, and 50 from eSignal...although I think IQFeed provides much more 1-minute data (maybe 1.5 years vs 6 months for eSignal). I have heard some discussion that DTN will be expanding their tick limit in the near future, but I don't have the details.
If you really need years of tick data, there is a solution in tickdata.com. More information on pricing and how to pull tickdata.com data into IRT:
http://www.linnsoft.com/tickdata/. You could purchase years of tickdata from tickdata.com, import that into IRT, and then continue to add another day each day from your realtime feed.
