Challenge 1: Valid Limit Order

Every matching engine starts with a precise order model.

Task

Implement new_order.

Rules

  • price == 0 is invalid.
  • quantity == 0 is invalid.
  • Otherwise construct and return the order.

This locks in the fields every later challenge uses: side, price, quantity, and timestamp.
