ASTX Event Contracts Product Description & Rules

ASTX
Updated

Dear ASTX Users,

To continuously expand our trading product offerings and meet the diverse trading needs of global users, ASTX is officially launching a new trading product — Event Contracts.

Event Contracts are an innovative trading product based on predicting the price direction of digital assets. Users do not need to set complicated leverage parameters. Instead, they simply predict whether the price of the specified underlying asset will rise or fall at the end of a designated period to participate in trading.

I. What Are Event Contracts?

Users select the trading asset, expiration period, and price direction:

Up or Down

When the contract period ends, the system will automatically settle the contract based on the prescribed settlement price.

  • Correct prediction: Receive the corresponding payout according to the rules displayed on the trading page, with the principal returned.
  • Incorrect prediction: The amount invested in the trade will incur a corresponding loss.

Event Contracts are simple to operate and require no leverage settings, allowing users to participate flexibly based on their market outlook.

II. Key Product Features

  • Simple Up/Down Prediction: Users only need to select “Up” or “Down” without setting complicated leverage parameters.
  • Automatic Settlement: Once the contract expires, the system automatically settles the position based on the settlement price specified by ASTX. No manual action is required.
  • No Liquidation Risk: There is no leverage or additional margin requirement. The maximum loss is limited to the amount actually invested in the trade.
  • Flexible Expiration Periods: Expiration periods ranging from 10 minutes to 12 hours are available, allowing users to choose based on market conditions and their trading needs.
  • Low Entry Threshold: The minimum trading amount is 1 USDT, allowing users to participate according to their individual risk tolerance.
  • No Early Closing: Once a contract is executed, it cannot be closed early. Profit or loss will be automatically settled upon expiration.

III. How to Participate

Enter the ASTX Event Contracts page:

① Select the Trading Asset
Choose the digital asset you wish to trade.

② Select the Expiration Period
Choose an appropriate trading period based on market conditions.

③ Predict the Price Direction
Select “Up” or “Down.”

④ Enter the Trading Amount
The minimum trading amount is 1 USDT.

⑤ Confirm and Submit
Review and confirm the trading direction, amount, expiration period, potential returns, risks, and other relevant information before submitting the order.

⑥ Wait for Automatic Settlement
Once the contract expires, the system will automatically settle the contract based on the final settlement result.

IV. Contract Pricing and Profit & Loss

Event Contracts use a binary settlement mechanism, where users predict whether the price of the underlying asset will be higher (Up) or lower (Down) at the time of expiration.

Settlement Rules

Result Return
Correct Prediction Receive 85% of the principal as profit, plus the full principal returned
Incorrect Prediction The entire principal is deducted, resulting in a 100% loss

Example

  • A user invests 100 USDT to purchase an “Up” contract.
  • If the price rises at expiration (correct prediction): the user receives the 100 USDT principal + 85 USDT profit, for a total of 185 USDT.
  • If the price falls at expiration (incorrect prediction): the entire 100 USDT principal is deducted, resulting in a 100% loss.

V. Trading Mechanism

1. Position Modes

  • Open/Close Position Mode: Within the same Event Contract market, users may hold both Up and Down positions simultaneously. All positions must be fully collateralized.
  • Buy/Sell Mode: Within the same Event Contract market, users may hold only a single-sided position, either Up or Down.

2. Order Rules

  • Event Contracts are priced and executed directly based on the Mark Price.
  • Users may cancel an order at any time before it is fully executed. For partially filled orders, only the unfilled portion may be canceled; the filled portion cannot be canceled.

3. No Liquidation Mechanism

Event Contract positions will not be forcibly liquidated and will not participate in the account-level liquidation process.

VI. Settlement Rules

  • Upon contract expiration, the system will automatically settle the contract based on the ASTX Price Index.
  • Correct prediction: Full principal returned + 85% of the principal as profit.
  • Incorrect prediction: Full principal deducted and the contract value becomes zero.
  • No fees are charged during the settlement process.
  • Settlement results are determined based on the ASTX Price Index at expiration. The settlement rules are transparent and publicly available and cannot be altered.

VII. Supported Account Types

  • Contract Account Mode
  • Multi-Currency Account Mode
  • Portfolio Margin Mode
  • Spot Account Mode is not supported

VIII. Risk Disclosure

  1. Event Contracts are high-risk financial products and may be subject to significant price fluctuations. Users should fully understand the product rules before participating.
  2. The maximum loss is limited to the amount paid when purchasing the contract and will not exceed the principal.
  3. This product does not constitute investment advice. Users are responsible for independently assessing their risk tolerance.
  4. ASTX reserves the right to suspend or adjust Event Contracts in the event of abnormal market conditions, system failures, force majeure, or other exceptional circumstances.
  5. If users are found to engage in market manipulation, malicious order placement, or other violations, ASTX reserves the right to cancel the relevant transactions and freeze the associated accounts.
