Free Traders are a special entity that exists only in the Market. Free traders will buy and sell all Resources on the market. All nations may purchase resources from free traders, but only nations with at least level 3 Cultural Skills may sell to free traders, with the exception of Gold and Silver which do not require any Cultural Skill to sell.
Free trader stock and prices[]
Free traders will purchase resources at a fraction of their average cost, and add the amount of resources purchased to a sell order at a price multiple times higher. Purchases on a specific resource from free traders will over time raise both the free trader buy and sell price of that resource, while selling more of that resource to them will lower the both the buy and sell price of that resource.
Trading with free traders[]
Generally trading with free traders will be less profitable than trading with other nations. Selling to free traders should be reserved to moments when a nation has too much of a resource in stock and not enough buyers, as their buy prices are very low for most goods (ores tend to be an exception). Buying from free traders should be avoided if a nation can produce a good on its own or trade with another nation to obtain the good, since free trader sell prices are often very high and their stocks tend to be unreliable.
Trading Gold and Silver[]
An exception to the above rule is selling and buying Silver and Gold from free traders. Free trader silver and gold prices tend to be profitable and mostly stable. Additionally the difference between the buy and sell price for these goods is usually 1 coin, so excess coins can be converted into stored gold and silver to avoid lowering Porcos' wealth, and then later be converted back into coins when needed at a very minimal cost.
