Using post-only limit orders to keep trading costs predictable in Turkey
Traders in Turkey who want maker pricing often place limit orders that fill instantly as taker by accident. How the post-only option works on Binance, OKX, Bybit and Bitget and when it is worth using.
Multiple exchanges | Turkey | TRY | fees, access and account safety
A limit order does not automatically earn the maker rate. If you set a buy price at or above the current best ask, the order matches immediately and is charged as taker, even though you chose a limit order. Traders in Turkey who try to keep costs down often discover this only when they review their history. Most large exchanges, including Binance, OKX, Bybit and Bitget, offer a post-only option that rejects an order if it would fill straight away, which does nothing about price movement but making the fee type predictable. This guide explains how it works, its trade-offs and how to test it.
Why limit orders sometimes pay taker
The fee type depends on whether your order adds liquidity to the book or removes it. A limit order priced so that it crosses the spread removes liquidity at once and is treated as taker. This often happens when the price moves between the moment you type the order and the moment you submit it, especially during busy market periods.
What post-only does
With post-only enabled, the exchange accepts the order only if it would rest on the book. If it would match immediately, it is cancelled or adjusted according to the platform's rules, which are described in the official help pages. The result is that any fill you do get is normally charged at the maker rate shown on the fee page.
The trade-offs
Post-only orders can be cancelled repeatedly in a fast market, and you may miss a move you wanted to catch. They suit patient entries and exits rather than urgent ones. If getting filled matters more than the fee, a normal limit or market order is the better choice, and you should simply accept the taker rate.
Test and review
Place a few small post-only orders and watch what happens when they would cross the spread. Then check the order history to confirm the fee type recorded. Keep a short log comparing your fees before and after using the option, so you can see whether it actually reduces your costs for the way you trade. Over a few weeks, that comparison tells you clearly whether the extra patience is worth it.
