The secondary progressed chart takes your natal and moves it forward basically 1 day from the day you were born for every year that you have lived.So if you were born July 1 2000 and you are now 11, your chart would have progressed to roughly July 12 2000. The age you are = how many days your chart will have progressed.
The outer planets usually stay in the same spot.
Retrograde planets may move further back, or may become direct by progression.
Very rarely will outers change signs, but sometimes they do.
You can compare your natal to progressed which is really an eye opener if you have not yet done so, especially when searching for answers at a crucial time. You will see the interplay between your basic natal and the person that you are growing into and how the two dynamics help or hinder.
