Open form and close form indicators

[m.ansari62]

I'm a trader who is interested in analyzing stock more than trading. 

Is there anyone who knows what is the difference between open form and closed form indicators in terms of formula. For instance open form Intraday Intensity(II) and closed form Intraday Intensity(II%)? 

In many books the Intraday Intensity defined as (2*close- high-low)/(high-low)*volume. I think it's the closed form of II. but what about the open form? I mean how could I calculate II% or closed form Intraday Intensity? I couldn't find any clue about the formula over the net. I will appreciate your help in advance, if you respond....
