To help you better understand and use the ASTX perpetual futures products, we have prepared the following frequently asked questions.
We strongly recommend reading this before you start trading.
1. What is a Perpetual Contract?
A perpetual contract is a type of digital asset derivative with no expiration date.
Users can use leverage to open long (bullish) or short (bearish) positions and earn potential profits from market price fluctuations.
2. How are futures trading fees calculated?
Fee Formula:
Fee = Trade Value × Fee Rate
ASTX Perpetual Futures Fee Rates:
• Taker (market order): 0.04%
• Maker (limit order): 0.04%
Notes:
• Opening, closing, and partially closing a position will generate fees.
• Unfilled or canceled limit orders do not generate fees.
3. What are Taker and Maker?
• Maker (adds liquidity)
Your order is placed in the order book and increases market liquidity.
• Taker (removes liquidity)
Your order is immediately matched with orders in the order book, reducing liquidity.
4. What are Cross Margin and Isolated Margin?
• Cross Margin
All available balance in the futures account is shared among positions.
⚠ If forced liquidation occurs, your entire futures account balance may be lost.
• Isolated Margin
Each position has its own independent margin.
Losses are limited to the margin allocated to that specific position.
5. What are Multi-Position mode and Merged-Position mode?
• Multi-Position Mode
Multiple positions in the same trading pair and direction are displayed and calculated separately.
• Merged-Position Mode
Positions of the same trading pair and same direction are merged into one position,
with unified PnL and margin calculation.
6. What is Transfer?
Transfer means moving funds between the Asset Account and the Futures Account.
The maximum transfer amount is based on what is displayed in the interface.
7. What is Margin?
Margin is the collateral required to open and maintain a perpetual futures position.
8. How is Margin calculated?
Both Cross and Isolated modes use the same calculation:
• Initial Margin (Opening Margin)
Margin = Position Size × Entry Price ÷ Leverage
• Position Margin (Maintenance Margin)
Same as opening margin, and does not change with price movements.
9. What is Forced Liquidation?
Forced liquidation occurs when a position’s margin is insufficient to keep the position open.
Consequences:
• Cross Margin:
Your entire futures account balance may be lost.
• Isolated Margin:
Only the margin assigned to that specific position will be lost.
