Does anyone know how to use this feature? I am looking for a way to view my "net" Greeks on my options portfolio. I believe I may have found the procedure, but I wanted to double-check. In addition, I am not sure how each column would be expressed in decimel form--only whole numbers are given with an implied plus or minus sign. For example, the given delta on my portfolio appears to be +37, gamma as -1, vega as -170, and theta as +231. How does this translate into a decimel? I do know the meaning or the positive and negative aspect. Thanks for your help.
