I don't think you can do that in TS. You will have to manually splice the contracts together. Figure out the roll dates and roll amount, then you need to add the roll to the previous contracts before you splice them together. This is a time consuming process.
Me too use UniServer. This is really the simpliest way to get continous contracts fi you use eSignal datafeed. But i have bought it from www.tssupport.com Do you know if is there any difference ??
