Volume indicator for up and down ticks separately?

Hello,
Could anyone give a hint how and indicator showing up and down volume on separate bars is called? Because the one in MT4 shows total value of tick activity during a period, but does not show how many up or down ticks happened.

Thank you.

have a look to an existing volume-indicator, for example http://www.forexfactory.com/showthre...40#post7119440

Thank you, but it's probably not what i'am looking for.
Lets say a volume tick indicator shows a total activity of 2000 tick on a single bar. What I would like to know is how much of those ticks were up and how much were down. ( For example it plots two bars, one showing 1500 up tick and the other 500 down ticks).

Maybe you know where i could locate such and indy?
