Street does not seem to have any useful condition with on balance volume

I am a new user of zerodha streak. I was hoping to use the on balance volume indicator. As far as I understand, we can only check whether the on balance volume indicator is trending up or down.

So there should be a value similar to a test for trending up or down when I’m trying to use an on balance volume indicator.

For example, in zerodha streak, I should be able to say that one of the conditions of entry are if the on balance volume indicator is trending up.

However, streak gives me an option of comparing the on balance volume indicator with some fixed number. That is of no use because the value of on balance volume can be arbitrary.

For example,http://stockcharts.com/school/doku.php?id=chart_school:technical_indicators:on_balance_volume_obv
states that “the absolute value of the indicator is not important. Charters should instead focus on the characteristic of the line”.

Is it possible for zerodha to modify this?
