SuperEx Guide: Index futures — Frequently Asked Questions
SuperEx Index Futures is an innovative futures trading product.
Users can use non-mainstream, small-cap cryptocurrencies as margin and profit-and-loss settlement assets to trade the index prices of major trading pairs such as BTC/USDT and ETH/USDT, enabling a futures trading experience where “altcoins leverage mainstream market trends.”
This product is priced based on multi-exchange index prices and combined with a perpetual futures mechanism. While ensuring fair pricing, it significantly enhances the capital efficiency and trading scenarios of altcoins.

If I transfer different margin currencies into the index futures account, will they be used as shared margin?
No. Different margin currencies in an Index futures account cannot be used as joint margin and are isolated from each other.
In the event of liquidation for a specific currency, traders will only lose the margin of that currency, and other margin currencies will not be affected.
Why is my execution price not reflected on the index candlestick (K-line)?
The index K-line represents a weighted average spot price aggregated from multiple exchanges and does not include execution prices from this platform.

In addition,index futures are not matched via an order book. Trades are executed based on the index price with an added spread, so the execution price may differ from the index price.
Why was my position automatically liquidated?
Your position may be automatically liquidated under the following circumstances:
When your margin balance is insufficient.
When your position profit exceeds the system-defined maximum profit limit, triggering forced closure.
In special situations, such as when the margin currency is scheduled for delisting.

What fees are charged for Index futures?
There are three types of fees involved in Index futures trading:
Trading Fees — Charged whenever an order is executed.
Position Holding Fees — Charged only if a position is held at settlement, usually every 8 hours, with adjustments based on market conditions.
Liquidation Fees — Charged when a position is forcibly liquidated.
Can ET be used to offset trading fees for Index futures ?
Currently, this feature is not supported, but it may be supported in the future.
What is a spread?
Since Index futures do not rely on order-book matching, trades are executed automatically based on the index price.
As a result, the actual execution price is calculated from the index price according to predefined spread rules. Currently, a spread is applied when opening a position. No spread is applied when closing a position by default.
Example
If the current BTC index price is 100,000 USDT and the configured spread is 0.05%:
Market Buy (Long) execution price = 100,000 × (1 + 0.05%) = 100,050 USDT
Market Sell (Short) execution price = 100,000 × (1 − 0.05%) = 99,950 USDT
