**Opening Fee: 0.02%**

**Closing Fee: according to the profit**

| ROE                | Closing Fee Rate |
| ------------------ | ---------------- |
| ROE <= 0%          | 0                |
| 0 < ROE <= 20%     | 10%              |
| 20% < ROE <= 50%   | 20%              |
| 50% < ROE <= 75%   | 30%              |
| 75% < ROE <= 100%  | 40%              |
| 100% < ROE <= 150% | 50%              |
| 150% < ROE <= 200% | 60%              |
| 200% < ROE <= 250% | 70%              |
| R > 250%           | 80%              |

eg. if your position margin equals 10 USDC, when you close the position at 160% ROE, the closing fee would be calculated like this:

The fee is calculated based on different profit brackets:

* For  0 < ROE <= 20%: Profit range:  10 \* 0.2 = 2 USDC   Fee:  2 \* 10% = 0.2 USDC
* For  20% < ROE <= 50%: Profit range:  10 \* (0.5 - 0.2) = 3 USDC   Fee:  3 \* 20% = 0.6 USDC
* For  50% < ROE <= 75%: Profit range:  10 \* (0.75 - 0.5) = 2.5 USDC   Fee:  2.5 \* 30% = 0.75 USDC
* For  75% < ROE <= 100%: Profit range:  10 \* (1.0 - 0.75) = 2.5 USDC   Fee:  2.5 \* 40% = 1.0 USDC
* For  100% < ROE <= 150%: Profit range:  10 \* (1.5 - 1.0) = 5 USDC   Fee:  5 \* 50% = 2.5 USDC
* For  150% < ROE <= 200%: Profit range:  10 \* (1.6 - 1.5) = 1 USDC   Fee:  1 \* 60% = 0.6 USDC

Final Fee Calculation: Fee = 0.2 + 0.6 + 0.75 + 1.0 + 2.5 + 0.6 = 5.65 USDC
