Maker or taker on OKX: how Australians can tell which fee they are paying
The same OKX trade can be charged as maker or taker depending on how the order meets the book. This guide shows Australian users how to identify each one in their history and adjust habits.
OKX | Australia | AUD | fees, access and account safety
Two trades of the same size on the same OKX pair can carry different fees, and many Australian users only notice when they compare their trade history. The reason is the maker-taker model. An order that rests on the book and waits to be filled adds liquidity and is charged as a maker. An order that fills immediately against existing orders removes liquidity and is charged as a taker. Understanding which one you are triggering helps you predict costs before you click, rather than discovering them at tax time.
How OKX decides which side you are on
Market orders always take liquidity, so they are charged as taker. Limit orders depend on price. If your buy limit is at or above the lowest ask, it fills straight away and is treated as taker. If it sits below the ask and waits, the filled portion is maker. A single large limit order can be partly taker and partly maker if some of it fills instantly and the rest waits. The fee schedule on OKX's fees page explains the tiers that apply to your account level.
Using post-only to stay on the maker side
If your aim is to always pay the maker rate, the post-only option is useful. It tells OKX to cancel the order rather than let it fill immediately as a taker. That gives you control, but it also means an order can be rejected in a fast market. Post-only suits patient traders placing orders away from the current price. For urgent trades, accepting the taker fee is often reasonable; the point is to choose it deliberately.
Where Convert fits in
The simple Convert or quick-buy screens are convenient, but they do not show maker or taker labels the same way the trading screen does. The cost is built into the quoted rate. If you regularly move larger amounts, compare the Convert quote with what a limit order on the spot pair would achieve at that moment, including the fee. Note the result in your records so you can judge which route works better for your typical size.
Reading your history for evidence
Export your OKX trade history and look at the fee column alongside the order type and execution role. Group trades by maker and taker and total the fees for each. Australians keeping records for tax purposes already need this export, so the extra analysis takes only minutes. If taker fees dominate, it often means habitually using market orders where a limit order a little away from the price would have done the job.

Scenario checkpoint
- Check each trade's execution role column to see whether OKX charged maker or taker.
- Use post-only when you want a limit order rejected rather than filled as taker.
- Compare Convert quotes with a spot limit order before moving larger amounts.
- Total maker and taker fees separately from your exported history each quarter.
