Maker Fee
The fee charged when your order adds liquidity to the book by resting until someone fills it.
Post a limit order that doesn't execute right away and you're a "maker": you've made liquidity for others to trade against. Exchanges reward this with a lower fee, sometimes zero or even a small rebate.
The logic is plain. Resting orders deepen the book and tighten the spread, which the venue wants. Maker fees typically run a few basis points below taker fees.
