Fast answer
Crypto maker/taker fee checks should show liquidity role, order type, post-only setting, fee tier, partial fills, and final net cost.
Before claiming low fees, record whether the order added or removed liquidity, the order type, post-only setting, immediate match state, fee tier, partial fills, and final fee charged.
A limit order is not automatically a maker order if it matches existing liquidity immediately.
Maker/taker checks
What to inspect in maker and taker fees.
Liquidity role
Maker orders add resting liquidity; taker orders consume existing liquidity.
Order behavior
A market order is usually taker, while a limit order can be maker or taker depending on fill.
Post-only control
Post-only settings can help avoid immediate taker execution but may cancel the order.
Partial fills
Different portions of an order may need separate fee treatment.
Source context
