Setting up a stop-limit order on OKX and understanding when it fills
A stop-limit order on OKX combines a trigger price and a limit price, and confusing the two is a common reason orders never fill. A careful walkthrough of the fields and how to test them with a small amount.

Stop-limit orders are often described as a safety tool, yet many OKX users discover too late that their order triggered but never filled, or never triggered at all. The reason is usually a misunderstanding of the two prices involved. The trigger price decides when the order becomes active, and the limit price decides the worst price at which it may fill. If the market moves quickly past your limit, the order can sit unfilled. This guide explains each field on the OKX order form, how to choose a sensible gap between the two prices, and how to practise with a small position before relying on it.
Trigger price and limit price
The trigger price is the level that activates your order. Once it is reached, OKX places a limit order at the limit price you entered. For a sell stop, the limit price is usually set slightly below the trigger, so there is room for the order to fill if the price keeps falling. If both prices are identical, a fast move can skip straight past them and leave your order waiting on the book.
Choosing the gap
There is no single correct gap. On active pairs with a tight order book, a small gap may be enough. On thinner pairs or during volatile periods, a wider gap gives the order a better chance to fill, but accepts a worse price. Look at the order book depth and recent price swings for the pair before you decide, and write the reasoning down so you can review it later.
Fees and order behaviour
Once triggered, your limit order may fill as maker or taker depending on whether it matches existing orders immediately. Check the official OKX fee page for the rates that apply to your account, and read the help center article for the exact behaviour of stop-limit, stop-market and other conditional orders. These details can differ between spot and derivatives, so confirm the product you are using.
Practise with a small amount
Before relying on a stop-limit to protect a meaningful position, place one on a tiny amount and watch what happens. Note when it triggered, whether it filled, and at what price. Then check the order history to see how OKX recorded it. A few small tests will teach you more about how the order behaves than any explanation, and they cost very little.

Scenario checkpoint
- Understand that the trigger activates the order and the limit sets the worst fill price
- Leave a gap between trigger and limit price so the order can fill on fast moves
- Check order book depth and recent swings before choosing the gap for a pair
- Confirm the fee rates and conditional order rules on the official OKX pages
- Test a stop-limit on a tiny amount and review how it appears in order history
