Rollover data

["Eric Langley" <elangley@xxxxxxxxxxx>]

 Does anyone know if there is a way to back adjust tick data (the previous
contract) in global server (or a service that does this). I am having a
problem with futures contract rollover due to the lack of consistent
starting data for my intraday systems to work properly.
  
For instance, an hourly bar system will run normally once the contract has
been trading for 10 days, but the first 10 days are erratic due to the
sporadic data.
  
 Any help would be appreciated.
