Is your velocity constant in space-time?

[nasageek]

I was just wondering are you always going at a constant velocity through space-time since, as your through space increases you time slows down and vice versa. So does this mean you are maintaining a constant velocity, and if so what is that velocity.

In special relativity, in an inertial frame, yes. Your space-time velocity is always the speed of light.

To avoid confusion with the usual 'velocity in space', it is better tp speak about 'rate of advance in space-time'. What you describe is one possible geometrical interpretation of SR visualized here:

The rate of advance in space-(proper)time in respect to coordinate time is c, for all objects.

If your velocity is c then what is the measure of your velocity through time?

Hi A.T. that link is a wonderful one!..very informative

If your velocity is c then what is the measure of your velocity through time?

The ratio of the times measured by a moving clock and the observers clock, can be viewed as the moving clock's 'velocity through time', in respect to that observer.
