Why a limit order can still be charged as taker: a guide for Kenyan traders

A common belief among new traders is that limit orders are always maker orders and market orders are always taker orders. The reality is a little more subtle, and it explains why traders in Nairobi, Mombasa or anywhere else sometimes open their trade history on Binance, OKX, Bybit or Bitget and find taker charges on orders they thought would rest on the book. Your role is decided by what your order does at the moment it arrives, not by the order type you selected. This guide explains how that works, how a limit order can cross the spread and fill instantly, what the post-only option does, and how to confirm your role after a trade so your records match your expectations. Fee levels themselves change over time, so always read the current schedule on each exchange's official fee page.

Maker and taker are about liquidity, not order type

A maker adds liquidity: the order sits in the order book waiting for someone else to trade against it. A taker removes liquidity: the order matches immediately against an order already resting there. A market order always takes, because it fills against whatever is available. A limit order can do either. If your limit price is below the best ask when buying, or above the best bid when selling, it rests on the book and becomes a maker order once someone else trades with it. If your price reaches or crosses the other side of the book, it fills straight away and is treated as a taker order.

How a limit order ends up crossing the spread

The most frequent cause is setting a buy price at or above the current lowest sell price, often because the trader wants to be sure of a fill or copied a price from a chart that was already out of date. In fast markets the price can also move between the moment you type a number and the moment you press confirm, so a price that was below the ask a second ago is now above it. Part of an order can also fill immediately as taker while the remainder rests as maker. Watching the live order book, not just the chart, before you submit makes these situations much easier to spot.

Using post-only to protect your intended role

Most major exchanges offer a post-only option, sometimes shown as a checkbox or as a time-in-force setting on the limit order form. When enabled, the exchange will reject or cancel the order if it would execute immediately, so it can only ever rest on the book as a maker. The trade-off is that you may not get a fill at all when the market moves away from your price. Post-only suits traders who are patient and care about their role on every order; it is less suitable when getting the trade done quickly matters more than how it is classified.

Checking your role after each fill

After a trade, open the order details or trade history on the exchange and look for the column that shows whether each fill was maker or taker, along with the fee charged. If one order was split across several fills, check every line, because the roles can differ. Record any surprises in a simple note: the pair, the price you set, the best bid and ask at the time if you remember them, and the role you received. After a few weeks, these notes reveal patterns, such as placing orders too close to the spread or trading during volatile moments, that you can adjust deliberately.

Scenario checkpoint

• Compare your limit price with the live best bid and ask in the order book before you submit any order.
• Enable the post-only option when you want an order to rest as maker and accept that it may not fill.
• Open the trade history after each fill and check the maker or taker label on every partial execution.
• Read the current fee schedule on each exchange's official fee page instead of relying on old screenshots.
