Limit vs Market Orders
A market order is the clearest path to taker status because it seeks immediate execution at the best available prices. That is why exchanges consistently link market orders with taker fees.
A limit order gives you price control, but it does not automatically guarantee maker pricing. If the limit crosses the book and fills instantly, it can still be charged as a taker trade.
Order type and order behavior are both important.
This distinction matters for traders who assume every limit order is cheap. In reality, the exchange looks at whether your order added liquidity first or consumed it at once.
Post only instructions exist to help traders keep an order from removing liquidity. If the order would take liquidity, the exchange typically cancels it instead.
For execution planning, it is often useful to decide first whether price control or guaranteed fill matters more.
