Kraken restricts customers from filling their own orders (simultaneously being the maker and taker for the same order). This removes the ability for wash trading which is a form of market manipulation in which an investor simultaneously sells and buys the same financial instruments to create misleading, artificial activity in the marketplace.
- If two orders of the same quantity would result in self-execution, the resting order will stay on the order book and the new order will be cancelled regardless of the size of the order.
- In the case that an order can be filled partially from the order book, the remaining volume that would result in a self match will be cancelled.
- If there are two resting orders, the first will have time priority and the second may cancel along with any remaining volume from the third aggressing order.
