Weekly data question

[Cigar]

What is 'weekly data'

Is it
1. Fridays closing price or
2. An average of the 5 closes in a week

I've got daily data on xcl, but want weekly data also.

thanks

As with daily data there is an open and close price, and the same applies to weekly monthly annually.

weekly e.g. Monday open - Friday close
