Fellow Binancians,

Binance Futures will adjust the Contract Size of USDⓈ-Margined SNDKUSDT Perpetual Contract commencing at 2026-11-20 01:00 (UTC) due to forward share splits of the Underlying Asset Issuer’s issued and outstanding shares. The adjustment is estimated to complete at 2026-11-20 05:30 (UTC) (the “Adjustment Period”). There will be a cancel-only phase which may last up to 5 minutes after the adjustment is complete. More details on the adjustment can be found in the table below: 

Please Note: 

• At 2026-11-20 00:30 (UTC), all strategy bots created on the aforementioned perpetual contract (including Grid, DCA and Snowball) will be terminated and all positions will be closed automatically regardless whether "Close all positions on stop" is enabled or not. The position of all strategy bots will not be reinstated after the Adjustment is complete. 

• During the Adjustment Period, a Suspension Session State will be implemented and all the open orders in the aforementioned perpetual contract, including reduce-only orders (TP/SL), will be canceled. Services of the aforementioned perpetual contract such as trading, closing position, order (placement, cancellation and modification), funding fee, mark price, price index and liquidation functions will be suspended during the Adjustment Period. The Mark Price and Price Index will not be updated during the Adjustment Period. 

• During the Adjustment Period, users with open positions on the aforementioned perpetual contract will be closed first. Unrealized PNL will be settled and credited to the users’ Cross Margin Futures Account regardless of the users’ position mode setting. For the users with open positions in isolated mode, the realized PNL and all margin balance in the Isolated Margin Futures Account will be transferred back to the Cross Margin Futures Account. After the adjustment is complete, new positions will be re-instated. The margin balance that will be transferred by the system to the Isolated Margin Futures Account is based on the initial margin requirement of the leverage level users have selected before the adjustment. 

• During the cancel-only phase, users are allowed to submit, modify or cancel Post-Only orders only. The duration of the cancel-only phase will be determined by Binance based on actual market liquidity and may last up to 5 minutes.

• At 2026-11-20 05:30 (UTC), the trading function resumes and Binance Futures will apply Last Price Protected (“LPP”) Mechanism on the aforementioned perpetual contract. It is highly recommended that users with open positions in the aforementioned perpetual contract re-assess their position before the trading is resumed to mitigate against price fluctuations that may occur.

• At 2026-11-20 14:30 (UTC), the LPP period of the aforementioned perpetual contract will end when a stable index price can be derived from third-party data vendors. The Mark Price will transition gradually from LPP mechanism to standard Mark Price calculation. The transition will be applied gradually by using mark price smoothing process to minimise sudden price movements and to better ensure price stability during the transition.

• The mark price and index price of the aforementioned perpetual contract before the adjustment will be retained and continued with the newly adjusted price after the adjustment is complete. 

• The last price continuous Kline (candlestick) chart of the aforementioned perpetual contract will be corrected within 24 hours after the adjustment is complete. 

• The adjustment completion could be completed ahead of the schedule.
