[amibroker] Is there a way of adding signals from a binary wave?

["mleonsprint" <mleonsprint@xxxxxxxxx>]

Is there a way to add each signal you get. So if right now I recieve 
a "1" and then the next period comes back ==1 then I need AB to say 
1+1==2.

I looked at barssince but that gives it in time, Is there a 
possibility of "signals since"?
