Futures expiration

[Guest]

Hi,

I'm currently using CL #F (Light Crude Oil futures) continuous contract for my formula.

In real trading, I have to specify the expiration month and year. Can someone tell me specifically how CL #F (or other commodity futures for that matter) get its prices, and consequently displays in the chart, during the transition from one contract period to another? Thank you.
