 monthly credit data
If you click on the graph, the spreadsheet with the underlying data is available. DEQ is also required to post the formula for the calculation.

The volume-weighted average price is calculated as the sum of the value (credit price * number of credits traded) of all transactions, divided by the total volume of credits traded over the month.
 
Volume Weighted Average Price=(∑^x▒〖(Transaction〗_x   volume*〖Transaction〗_x  price) )/(∑^x▒〖〖Transaction〗_x  volume〗)
