What is a prograde orbit?

[Lopez de la Osa]

You can call me stupid, but, what is exactilly a 'prograde orbit'? Is the same that a anti-clockwise orbit? Does it depends on the direction of the body I am orbiting?

Yes, you're right.

No planetary body orbit is retrograde in stock KSP

[ElWanderer]

A prograde orbit is in the same direction as the rotation of the parent body. A retrograde orbit is in the opposite direction.

I don't know the exact convention. In KSP everything rotates in the same direction. That is prograde. If you view that from the "top" looking at the northpole, that is anti-clockwise or mathematically positive. But: If you look at it from below, looking at the south pole, it actually is clockwise! That's why we use terms like prograde and retrograde to make it clear. :]

My simple way of looking at it:

1. As long as you're on the planet, prograde is heading towards the sunrise. Retrograde is heading towards the sunset.

2. Once you're in an orbit, prograde is the same direction as your orbit and retrograde is the other way around.

Lots of thanks to all of you. It is so pleasant to know that here I will have the help I need...
