The market works like an automated system for buying and selling items through orders. You can create buy or sell orders in Keeps, which can be partially filled and are easy to search.
The market will guarantee that players receive or sell the requested item for the price they have specified. The request can be fulfilled immediately, or possibly wait for a better price if no immediate fulfillment is possible or not ideal.
Buy/Sell Order
They are functionally identical, with the main difference being that buy orders are waiting to buy something, and sell orders are waiting to sell something, respectively. A buy order asks for an item to be provided within the range set on the buy order and offers money, while a sell order asks for money and offers an item, which will be sold at the keep where the sell order was created.
Market Order matching
As described above, the broker system will try to match buy and sell orders immediately at every creation or change of an order by the following rules, before (re)listing the respective order on the market:
Sell Order Creation/Change:
When you create or change a sell order, the system matches it with the highest-priced buy orders that meet your asking price and are within range. The highest-priced buy order is filled first at your asking price. If your sell order has more items than the buy order needs, the remaining items go to the next highest buy order. This continues until all items are sold or no more matching buy orders exist. Any leftover items are listed as a new sell order.
Buy Order Creation/Change:
When you create or change a buy order, it matches with the lowest-priced sell orders that meet your offer price. The lowest-priced sell order is filled first, and the seller gets the price you offered. If your buy order needs more items than the sell order provides, the next lowest sell order is used. This process repeats until your buy order is filled or no more matching sell orders exist. Any remaining demand becomes a new buy order on the market.
Broker Fee and Sales Tax
The broker fee is due on order creation for all non-immediate orders and is based on a percentage of the total order value. It would be a Minimum of 100 LUX or 3% of the order value.
Sales taxes are due after an item has been sold and are paid by the seller. They will be automatically deducted from the sales transaction.
Changing Order Prices
When modifying the price of a market order, another Broker Fee is due.
