This will be split into 2 parts: The NPC market, where the players buy items and sell them for the base price seen in
$$price, and the player market. Just a quick reminder, what you can't buy in the NPC market, you can trade in the player market.
Note: Assets listed may have icons next to them. A scale icon indicates that the asset can only be bought from player market. A pink and yellow bag icon indicates that asset can be sold in retail stores.
The NPC Market is the original market for all your essential needs ever since Update 1.0.0. You can buy and sell there for the prices in the assets page($$"val,value,price"without asset name at end can be used to reach npc market prices).
Ever since Update 1.5.0, the player market is a way for us to trade between corporations and keep the economy and playing field diverse. For example, one might need furniture for headquarters building but doesn't want to produce furniture. You can instead buy furniture from another player who is creating excess, say because they need retail shop and have ten furniture factorys which actually would produce more furniture than is needed.So at the end you buy your furniture and they get free capital for having ten furniture factorys.
Here are some prices for assets (updated since v.1.11)
GAS ENGINE: $10.3k-11k
Research Chemical: $150-$200
If nobody else is selling, supply and demand should tell you to sell for more. Likewise, a massively overproduced item is NOT worth selling for the prices above. This ranges a span of about 20% higher or lower.
