Hi, you will see from the attached that overlaying the VPOC value from source chart #14 works fine (value=5038.00). However, subtracting this value from its previous value results in a zero output. Please lmk if you need more information. Thanks

There is nothing attached, so we are not sure what you are referring to. Also, how are you doing the subtraction?

In your "Study Subgraphs Difference" study you are using the same subgraph for "Input Study 1" and "Input Study 2", therefore a result of 0 is correct.

Yes, same input, but the 2nd one is offset by 1 period, and the source chart is has a daily timeframe. Hence I am trying to see the difference of the current VPOC minus the previous period VPOC.

RESOLVED- In the current day's example, VPOC happens to equal VPOC[-1] by coincidence, hence the zero value. When tested with a lookback period of 2 or more, the value changes as it should. Thanks and apologies for your time.
