it's simple, install version 1.05, play it, then you will understand in version 1.30

Sorry but version 1.3 of fairy empire has a completely different map for trade mode.

I do not understand the question. I will try to explain, but I have poor English. What exactly is the problem? Trading is easy. Fly close to the station by all ships including fighter jets. Click on the station a trade window will open. Select the product you want to buy, enter the number. Make sure your fleet has storage space. Confirm the purchase; the window will close and the goods will begin to be reloaded into your fleet when the window opens again. The farther the ship from the station, the longer the exchange will be. At the top in the middle, the end time and the speed of the exchange are shown.
The trading window is the same in all versions of the game. Stations with which you can trade or buy ships or take missions, they are highlighted in a circle. You will understand if you move the camera away.

ok, thank you for your reply.

It's laughable that someones response was to play 105 to understand it. First off, this isnt a real english translation. it was a half arsed attempt that was given up when half way done. The only real true english modes were done independently.

check moddb for a rather good english translation that was done independently
