The pre-market price of YB on Whales Market is 1U, and if it hits, the return is about 4x. If you want to lock in profits, you can place an order first, because the mechanism of Whales Market is infinitely friendly to sellers, mainly for two reasons: 1) You only need to provide 100% margin. 2) After the 4-hour delivery period ends, if the buyer does not actively cancel, the order's pending delivery status remains valid. If you sell YB at a pre-market price of 1U, the results are as follows: 1) If the price of YB is below 1U after opening, you can directly deliver and settle at 1U, locking in profits. 2) If the opening price of YB is above 2U, you can sell YB directly in the secondary market, giving the margin to the seller, and the amount above 2U is your additional profit. 3) If the opening price of YB is between 1-2U, you can wait a bit; if the price does not exceed 2U, you can proceed with the delivery. If you sold YB above 2U, but within 4 hours, or if 4 hours have passed and the seller forgot to cancel the order, and YB drops below 1U again, you can buy back YB to complete the delivery, reclaim the margin, and take another position. For sellers: If the price is below 1U, you lose money. If the price is above 2U, you make money, but there is a high probability of default, only earning the margin. If the price is between 1-2U, you earn the difference.
