Every contract trade executed on the All InX platform incurs a trading fee. Below is a detailed explanation and calculation method for your reference.
1️⃣ Fee Deduction Overview
When placing a contract order, the system will reserve the estimated opening trading fee, calculated based on the order price and quantity. The actual fee is deducted only upon execution, based on the final transaction price.
✅ If the order is fully executed and the reserved fee exceeds the actual fee, the remaining amount will be refunded to your available balance.
❗ Both makers (limit orders that add liquidity) and takers (market orders that remove liquidity) are charged fees.
2️⃣ Trading Fee Rates
Order Type | Fee Rate |
Maker (adds liquidity, e.g., limit orders) | 0.04% |
Taker (removes liquidity, e.g., market orders) | 0.05% |
3️⃣ Fee Calculation Formula
🧮 Fee = Contract Size × Quantity × Execution Price × Fee Rate
📌 Parameter Definitions:
Contract Size: The value of each contract unit. For example, each BTCUSDT contract represents 0.001 BTC.
Fee Rate: Based on the order type (Maker or Taker).
Execution Price: The actual price at which the trade is executed.
4️⃣ Example
Trader A places a market order to buy 100 BTCUSDT contracts:
Contract Size: 0.001 BTC
Execution Price: 18,000 USDT
Fee Rate (Taker): 0.05%
💡 Fee = 0.001 × 100 × 18,000 × 0.05% = 0.9 USDT
Thus, Trader A pays a 0.9 USDT fee for this transaction.
📌 Additional Notes
Both opening and closing trades are charged fees separately.
All trading fees are settled in USDT and deducted immediately.
