Well, when you calculate cum(v) and then take its value when you
have a new day and subtract, you are actually getting the traded
volume for all day long MINUS the volume of the bar where the change
of day happened. Thus and in order to get the cum(v) for the
previous day, you simply use the ref(cum(v),-1).
