Trading

Trading is a piratey activity of commerce. Pirates purchase commodities at islands and then sail them to other locations to be sold for a higher price. Commodities can either be purchased directly from shoppes and stalls or using the market bidding system at commodities markets, forts, and palaces.

Sometimes fruit running is said to be a form of trading, as pirates must pay jobbers for fruit generated and then must transport it to another island to be sold on for profit.
