HeyUgly,

The reason why the numbers are both negative is that Sierra Chart always does the delta calculation as Ask minus Bid. It is never the opposite. So for a Diagonal Delta, the Ask side is calculated as the following:
(Ask at Current Price) - (Bid at Next Lower Price)

And the Bid Side is calculated as the following:
(Ask at Next Higher Price) - (Bid at Current Price)

As to the 1082, -344, and -144, we can not say. Although from the previous image you gave, it looks like these values are all correct, as they are aligning with what you show in your study. So we do not understand what exactly is the problem with these values.
