What exactly is happening to your VWAP study when you increase the Volume Per Bar?

Hi

I followed the instructions and retake the screen photo: http://www.sierrachart.com/image.php?Image=1615502195624.png

The problem is when I change the volume per bar from 500 per bar to 5000 or above, at the settings section of the DAY-VWAP (Volume Weighted Average Price), the study does not work anymore and changes to this: http://www.sierrachart.com/image.php?Image=1615502784444.png

It was working until today with 7000 volume per bar but this morning everything mixed.
I just want to turn it to normal and use it at any volume per bar as usual.
Many thanks for your help in advance

What you are seeing is normal due to how VWAP is calculated and that you have it set to calculate on a one day period. Since you have many days in which there is a single bar for the day, there is no way for the Variance of the VWAP to be calculated (it needs more than one data point).

You can do a few different things. One option is to set the Input for Use Underlying Data to Yes. This will give more data points on a per day basis which will then give you some Variance lines. Or you can use a different option for Std. Deviation Band Calculation.

Refer to the information for the study here:
Volume Weighted Average Price (VWAP) with Standard Deviation Lines

I have managed to download the same study from a source and deleted my old chart books, everything is ok now .

If you are not using the standard VWAP study that is provided within Sierra Chart then we cannot say. You would need to ask the creator of the study that you are using.
