Calculating Swing Volume

[aligator]

Dear Support,

Looking for a sample expression to calculate a swing total volume.

I am using the following example code to return the sum of the values for the Volume taken over the swing period between the swing high and the swing low. Then the value is printed as Draw.Text over the Swing high:

double swingVolume = SUM(Volume, SwingHighBar - SwingLowBar)[CurrentBar - SwingHighBar]); where the period is the difference between swing high/low index bars

This approach works fine. however sometimes an error is generated that the "period" for "SUM" is a negative value.

Any idea or referring to a sample script to calculate the Swing total volume correctly is appreciated.

Thanks.

Hi aligator, thanks for your note.

The negative value is coming from this calculation:
SwingHighBar - SwingLowBar

So the trivial way of fixing it would be to only do the calculation when SwingHighBar >= SwingLowBar

Unfortunately, I'm not aware of any script doing this already.

Please let me know if I can assist any further.
