Definitions of “Maker” and “Taker”

What is a Maker Order?

When you place a Maker order, you’ll enter the order price (either higher or lower than the current market price) and rather than being filled immediately, your order will go onto the order book. Your order will stay on the order book until another user takes the initiative to fill the order.

What is a Taker Order?

When you place a Taker order, you’re taking the initiative to fill your order by trading with an existing order on the order book. Your order trades immediately by filling an existing order with a matching price.

How are transaction fees calculated?

Formula for Pro Mode transaction fees:

Transaction fee = Nominal value × Transaction fee rate

Nominal value = Number of futures contracts × Transaction price

For Aster Pro mode traders, Maker fees are 0.01% and Taker fees are 0.035%.

For example,

Buying BTCUSDT Futures using a Market Order:

Nominal value

= Number of futures contracts × Transaction price

= 0.1 BTC × 80,000

= 8,000

As a Taker, you would pay a transaction fee of 8,000 × 0.035% = 2.8 USDT.

Once the price goes up, you can place a Limit sell order:

Nominal value

= Number of futures contracts × Transaction price

= 0.1 BTC x 85,000

= 8,500

As a Maker, you would pay a transaction fee of 8,500 × 0.01% = 0.85 USDT.
