Units used for offset in condition builder

[verge]

Please refer to "Condition Builder - Checking for Volume Expansion" in the help guide to understand my question.

The example shows how the build the following condition:
"Current value of Volume is greater than or equal to the value of Volume of 1 bar ago + 300%"

What if I wanted to not use percent. Lets say the condition I want to test for is:
Current value of Volume is greater than or equal to the value of Volume of 1 bar ago + 2000

Should I then use "tick" - or does tick only apply price?

You want to select an offset type of Price to input in an absolute value for the offset.
