Binance to Adjust BITOUSDT Perpetual Contract Quantity on November 19 Due to BITO ETF's 1-for-2 Reverse Stock Split

November 10 - According to official sources, due to the 1-for-2 reverse stock split implemented by the ProShares Bitcoin ETF (BITO), Binance Futures will adjust the contract value of the USDⓈ-M BITOUSDT perpetual contract starting from 09:00 (Beijing time) on November 19, with an adjustment coefficient of 0.5, expected to be completed by 11:30. This reverse stock split means that every 2 pre-split shares are consolidated into 1 post-split share, and the stock price is correspondingly increased proportionally.

During the adjustment period, trading of the BITOUSDT perpetual contract will be suspended, all open orders (including take-profit and stop-loss orders) will be canceled, existing positions will be closed first, and unrealized profit and loss will be settled to users' cross margin contract accounts.

Related grid, DCA, and snowball strategy bots will be terminated at 08:45 Beijing time, their positions will be automatically closed, and they will not be restored after the adjustment is completed. Trading is expected to resume at 11:30 Beijing time, followed by a post-only phase lasting up to 5 minutes, during which only submission, modification, or cancellation of Post-Only orders is allowed. After trading resumes, Binance will temporarily enable the Latest Price Protection (LPP) mechanism, expected to end at 22:30 that day, and gradually transition to standard mark price calculation.
