Revised Tier Structure Explained
Core Parameters by Asset
| Asset | Base Position Limit | Increment per Tier | Base Maintenance Margin | Base Initial Margin |
|---|---|---|---|---|
| BTC | 2,000 | 10,000 | 0.5% | 1.0% |
| ETH | 10,000 | 20,000 | 1.0% | 2.0% |
| EOS | 10,000 | 20,000 | 1.0% | 2.0% |
| LTC | 10,000 | 20,000 | 1.0% | 2.0% |
| BCH | 10,000 | 20,000 | 1.0% | 2.0% |
| ETC | 10,000 | 10,000 | 1.5% | 3.0% |
| XRP | 10,000 | 10,000 | 1.5% | 3.0% |
| TRX | 5,000 | 5,000 | 2.0% | 5.0% |
| BSV | 5,000 | 5,000 | 2.0% | 5.0% |
Tier Calculation Formulas
| Metric | Formula | BTC Example (Tier 3) |
|---|---|---|
| Position Limit | Base Limit + (Tier-1) × Increment | 2,000 + 2×10,000 = 22,000 |
| Maintenance Margin | Base Rate + (Tier-1) × 0.5% | 0.5% + 2×0.5% = 1.5% |
| Initial Margin | Base Rate + (Tier-1) × 0.5% | 1.0% + 2×0.5% = 2.0% |
| Maximum Leverage | 1 ÷ Initial Margin Rate | 1 ÷ 2.0% = 50x |
All assets maintain a 0.5% incremental rate for both margin types, with maximum maintenance margin capped at 50.0%.
