I have just come across these old guides after they were bumped and I only saw three missing aspects of successful trading:
CAU6-8
Turret steering
Type 4 guns (if you fly solo), Type 3 when in convoys
Set a direct waypoint to the next safe base.
Turn your nose there
Enter Turretview
Zoom out quite a bit
Thrust towards the base while gunning
Evade snacs/Novas with turretsteering (you know when he is firing if you zoomed out correctly)
If he Novas you, gun his shields off, regen your small civi transport shield and reverse (he blows up in the Nova detonation)
If in a Btrans, you might want to attack Nova bombers aggressively as you cannot run&dodge.
If you win, be nice to the pirate player and say something friendly in green.
If you lose, be nice to the pirate player and say something friendly in green.
