Script to count signals(arrows)

Hi,

I'm wondering if it would be possible to make a script or indicator that can count the signals(arrows) of another indicator. This must work in the 'Indicator' Strategy Tester, so I can run the indicator and easily see how many signals there were/are in totall.

I tried an ObjectsTotal script but for some reason the arrows that paint, aren't listed an an object in the object list.. Any of you know a way to get this to work? 

Please ask if you need clarification or have questions.
