Post only

Most likely, you have already read the information about the types of orders on WhiteBIT. However, there are two more functions in the Limit order interface that are worth paying attention to - the Post only and IOC toggles. In this article, we will try to analyse their features as briefly as possible.

It's very simple. Post only and IOC are a few more order types implemented on our platform in the form of convenient switches and used only in combination with a limit order.

These options allow you to improve the efficiency of your trading strategies and manage risks. Let's have a closer look at how exactly.


This toggle ensures that the limit order is 100% placed in the order book and executed as a maker. (The user pays the maker's fee accordingly.)

Please note that if an order cannot be added to the order book, it will be automatically cancelled. The relevant information is indicated in the tooltip that appears when you hover over the toggle.

This switch will be useful for those who have more favourable conditions for maker fees and want to guarantee the execution of an order with a maker role when trading on the market.
We would like to remind you that favourable conditions for makers can be obtained by Holding WBT. You can read more about the terms and conditions on this page.


Immediate-Or-Cancel. Orders with this parameter are not placed in the order book. The user always pays the taker's fee. When this option is activated, all or part of the order is requested to be executed immediately (taking into account the more favourable price), and any unfilled parts of the order are cancelled automatically.

Please note: a limit order with the IOC parameter will never be included in the order book, it must either be executed/partially executed or cancelled (fully or partially).
