Base exchange rates; reputation changes the price.
The credit price is rounded up after the faction reputation multiplier: neutral ×1, friendly ×0.80, ally ×0.65, wary ×1.50. Travelling traders share each culture’s quota across the crew and worlds for two home days. Credit purchases and barter consume the same stock. Stations use their own shipment stock. All listed materials must be analysed before a credit purchase.
