Order Placement Rules

  • Orders are always placed for your active company.
  • Order region is your company’s home region.
  • Buy orders require sufficient available cash.
  • Sell orders require sufficient available inventory.
Validation:
  • Price must be positive.
  • Quantity must be a positive integer.

​
Reservation Behavior

  • Buy order reserve: price * quantity is moved into reserved cash.
  • Sell order reserve: quantity is moved into reserved inventory.
When an open order is canceled, remaining reserves are released.

​
Matching Behavior

Matching runs per week by item and region.
  • Buy priority: highest price first, then earlier time.
  • Sell priority: lowest price first, then earlier time.
  • A trade happens only when best buy >= best sell.
  • Execution price uses the resting (older) order’s price.
Settlement updates:
  • Buyer cash decreases, reserved cash decreases.
  • Seller cash increases.
  • Inventory moves seller -> buyer in the same region.

​
Refresh Behavior

  • Market tables refresh after actions and when the week changes.
  • Tick-based refresh is debounced (short delay) to avoid flicker.

​
Player Tips

  • A large gap between open buy/sell prices means fewer immediate fills.
  • If “My Orders” stays open for many weeks, check your price vs current order-book priority.
