These people were wondering the same thing. TOS does this for ya i think, I often wondered how but I figure that is why I pay them so much freaking money! What do your daily's look like? Or are you talking about a daily for further out month?
Be very, VERY careful with TOS. When you use /CL without a contract specifier they give you a continuous that is just the prices run together without any adjustments at all. Which is fine and one valid way of doing it, as long as you know it.
If you use their Prophet Charts you can get either unadjusted or adjusted continuous contracts. CL1600 is unadjusted, and CL1700 is adjusted.
And lastly, the TOS charts daily /CL is so terrible it's not even funny. Just about everything is wrong with them. Intra-day charts are fine though.
