Data rollover

["drwar" <drwar@xxxxxxxxxxx>]

Could one of the experts comment on which of these two methods is preferred to produce a continuous contract.

1) Forward Adjusted
2) Back Adjusted

It seems to me that if the names are acutally what they do that Back Adjusted would be preffered such that you are modifying History to match up with latest data.

Please comment. The Intraday Tick Data I am downloading comes with a program which only allows these two techniques.


Thanks
