1. When Do Maker and Taker Fees Apply? What's the Difference Between Them?
A taker order occurs when you place a trade that immediately matches an existing order on the order book. Taker orders incur fees based on the taker fee rate.
A maker order happens when you place an order that rests on the order book at your specified price and quantity (e.g., limit orders that remain visible until matched). Maker orders are charged based on the maker fee rate.
Key Differences:
- Maker orders add liquidity to the market by increasing order book depth
- Taker orders remove liquidity by matching existing orders
- Maker fees are typically lower than taker fees to incentivize liquidity providers

6. How Are Trading Fees Calculated?
Fee Calculation by Instrument:
| Instrument | Formula | Example |
|---|---|---|
| Spot/Margin | Fee Rate × Crypto Amount Traded | 0.1% × 1 BTC = 0.001 BTC |
| USDT Futures | Fee Rate × (Contracts × Multiplier × Contract Size × Execution Price) | 0.05% × (100 × 1 × 0.01 × $20,000) = $10 |
| Crypto Futures | Fee Rate × (Contracts × Multiplier × Nominal Value / Execution Price) | 0.05% × (100 × 1 × 100 / $20,000) = 0.00025 BTC |
| Options | Min(Fee Rate × Multiplier × Contract Size × Contracts, 12.5% × Premium × Multiplier × Contract Size × Contracts) | Min(0.03% × 0.01 × 1 × 100, 12.5% × 0.05 × 0.01 × 1 × 100) = 0.0003 BTC |
