Total Volume current and prior day

Sorry, Just forget to say that I add data back to the chart like the last 15 days or so on Minute and Daily chart but is still same error exactly.

Hello Mike.A,

Thank you for your reply.

Now that your script is looking for the values from up to 3 bars ago, you will need to adjust your CurrentBars check. Here is what you currently have:

if (CurrentBars[0] < 1 || CurrentBars[1] < 1)
return;

Since you are wanting to check a value from Closes[1])[3] then you will need to make sure that there are at least 3 bars on the chart before this is calculated. We have a page about making sure you have enough bars here:

If you adjust the statement to the following, I suspect it should resolve the error:

if (CurrentBars[0] < 3 || CurrentBars[1] < 3)
return;

Please let us know if we may be of further assistance.

Hello Mike,

If you change a barsAgo reference from 0 to 1, you would be changing from "the current processing bar" to "the previous bar."

Similarly, changing a barsAgo reference from 1 to 2, you would be changing from "the previous bar" to "2 bars ago"

When scripts start processing, they start on bar 0, then process bar 1, bar 2, etc.

If we reference 1 bar ago on bar 0, that "1 bar ago" is not yet available to the script because it has not been processed yet.

So you need to make sure that if the script is processing before bar 2, it is not referencing 2 bars ago.
