Buy-Sell Order Management System on Bitkub Exchange

When you place buy or sell orders, the system will send your orders to the order book and wait for matching. Bitkub Exchange has criteria to prioritize the orders as follows.

We use a first-in-first-out (FIFO) system to prioritize buy-sell orders for both Limit orders and Market Orders. Normally, the system sorts buy orders with the highest prices first. However, if there are new higher bid orders and ask orders, Bitkub will sort these new orders instead. This also applies to sell orders. The sell orders with the lowest prices will be prioritized. Moreover, Bitkub will prioritize on a timestamp basis if there is more than one order at the same price.


In the case of a stop-limit order, when the price reaches the stop-limit spot, the system will automatically send a Limit order to match the specified prices of buy-sell orders. Likewise, Limit orders and Market orders are prioritized based on a timestamp basis.

Order Matching

In short, our system will match buy-sell orders in the order book sequentially, which is prioritized by the following.

1. Best orders prices
2. Earliest submitted orders
