OKX has announced the listing of Momentum (MMT) on its spot trading markets, with trading set to commence on November 4, 2025. The listing will follow a structured timeline to ensure a smooth introduction to the market.

Deposits for MMT will open at 6:00 am UTC, followed by a call auction from 11:00 am to 12:00 pm UTC. Spot trading for the MMT/USDT pair will begin at 12:00 pm UTC, with withdrawals available from 3:00 pm UTC on the same day.

Risk Control Measures and Trading Rules

To manage market volatility during the initial phase of trading, OKX will implement specific risk control measures. For the first five minutes after trading begins, market orders will not be allowed, and the maximum amount per limit order will be capped at $10,000. Additionally, the maximum net position per user is set at $10,000. These restrictions will be lifted after the initial five minutes.

Price limit rules will be applied to ensure stability. Initially, closing price-based limits will be used until a stable index price is available, after which index-based limits will be adopted. The platform reserves the right to adjust parameters or switch calculation methods based on market conditions without prior notice.

Call Auction Mechanism

The call auction mechanism will be employed for the MMT/USDT listing, lasting for one hour. This process allows users to submit buy and sell orders at desired prices before the official start of trading. The system calculates an indicative opening price based on these submissions.

During the call auction, the total value of each user’s buy orders is limited to $50,000. In the last five minutes of the auction, users can place orders but cannot cancel or modify them. Following the auction, the project team’s opening price will be displayed as the initial price on the trading chart, though it will not affect the execution prices.

Momentum, the asset being listed, operates as an operating system designed to facilitate seamless trading of crypto and real-world assets on the SUI platform. More details about the listing can be found here.
