Need a tradeing script.

[commander1102]

In my curret game I have run out of astroids (not being mined) near my main system but still need more ore and silicon. the nearest good source is 12 systems away (a little to far for stations to go and get them selfs).
in both systems I have a tradeing post that stores. energy cells, ore and silicon.
The one by the mines has ships buying stuff to keep it stocked.
Now.
Is there a script that lets me make a ship.

Buy X goods at a certain station. (and make sure it has X energy cells)
use the jump drive to go to the 2nd system.
Sell all goods at a certain station then make sure it has energy cells to get back to the 1st system.
Then start again.

(and use the money from the station it is selling to)

I need a script that can do this.
