Call Auction and Price Limit Rules
The SOPH/USDT spot listing will utilize a call auction mechanism, allowing users to submit buy and sell orders at desired prices before trading officially begins. During the call auction, the total value of each user’s buy orders is limited to $50,000. In the final five minutes of the auction, users can place orders but cannot cancel or modify them. The indicative opening price will be calculated based on these submissions.
OKX has outlined price limit rules to manage volatility when a stable index price is unavailable. Initially, closing price-based limits will apply, transitioning to index-based limits once a stable index price is established. The platform may adjust parameters or switch calculation methods based on market conditions without prior notice.
