Upticks and Downticks indicator

Hello all,
Does anyone know about/has an indicator showing the number of upticks and downticks (just to be clear, the number of ticks in a bar that pushed the price up or down, respectively (Upticks + Downticks = iVolume)). I would need an indi that allows me to use the number of upticks and downticks within a robot.

Thanks a lot...

Upticks + Downticks != Volume

a tick can also be a movement of the Ask price.
