Q: What is a Position Bracket (Tier)?
A: A Position Bracket, or Tier, is a classification of your position based on its USDT size. Each tier defines the maximum leverage you can use and the maintenance margin required. Larger positions fall into higher tiers with lower leverage limits and higher maintenance margin.
Q: How is Maintenance Margin calculated?
A: Maintenance Margin (USDT) = Notional Position Value × MMR − Maintenance Amount
Maintenance margin is always based on the Mark Price, which determines liquidation risk in real time.
Q: Does my Position Bracket affect liquidation?
A: Yes. Higher-tier positions require more maintenance margin, which increases the likelihood of liquidation if your margin is insufficient. Additionally, when moving to a higher tier, the maximum allowed leverage may decrease, affecting how much you can add to the position.
Q: What is the difference between Isolated and Cross Margin in the Position Bracket system?
A:
-
Isolated Margin:
- Order placement and tier checks use Average Entry Price (entry-based).
- Liquidation uses the Mark Price.
- Only the margin allocated to that position is at risk.
-
Cross Margin:
- Order placement and tier checks use Mark Price (market-based).
- Liquidation also uses Mark Price.
- All account equity can be used to cover positions; liquidation occurs if total equity < sum of tiered maintenance margins.
Q: Can I place a new order that exceeds my current tier?
A: Not directly. If the new order would bring your total position size into a higher tier:
- You may need to reduce leverage or add additional margin.
- The system automatically calculates the maximum allowed leverage for the new order to ensure total effective leverage stays within the tier limit.
Q: What happens if I add to my position in Isolated Margin?
A:
- The system checks tiers using your entry-based position.
- You can sometimes remain in the current tier even if the Mark Price has increased.
- If the new combined position exceeds your current tier, leverage for the new order will be capped according to the new tier limit.
Q: What happens if I add to my position in Cross Margin?
A:
- Tier checks use the current Mark Price of your existing position.
- Any price appreciation immediately affects your tier, which may lower maximum leverage for new orders.
- You may need to use lower leverage for the new order to keep total effective leverage within the new tier.
Q: How does leverage change when my position moves to a higher tier?
A:
- Higher tiers have lower maximum leverage.
- If your existing position is above the new tier’s maximum, Flipster automatically caps the leverage for new orders to keep total effective leverage within the tier limit.
Q: Where can I see the tiers and maintenance margin for each token?
A: Check the Trading Rules Page for token-specific Position Brackets, maximum position sizes, maximum leverage, and MMR values.
Q: Can I open multiple positions in the same symbol that cross different tiers?
A:
- Yes, but Flipster calculates the total effective leverage for all positions in that symbol.
- The system may limit leverage for new orders to ensure total effective leverage does not exceed the current tier limit.
