IV. Risk warnings

Trading suspension: all trading activity is suspended during the rebase. You cannot place, modify, or cancel orders during this window. Please plan your positions accordingly.
Rounding differences: prices and position quantities are aligned to the price increment and minimum order size during the rebase, which may introduce minor rounding differences. These are settled as small balance adjustments.
Review your orders after the rebase: please review all open orders, TP/SL, and strategy configurations after the rebase completes to confirm your positions are properly protected.
No fund-share ownership: Stock Perpetuals are derivative contracts. A stock split or reverse split rebase does not confer any ownership of, or claim on, the underlying fund's shares. The contract is cash-settled exclusively in USDT.
Advance notice: OKX will notify you before, during, and after each scheduled rebase. Please monitor OKX announcements and in-app notifications. In the event of an unscheduled or expedited rebase, advance notice may be shorter or may not be possible.
OKX discretion: OKX reserves the right to modify, delay, or cancel a scheduled stock split or reverse-split adjustment in exceptional circumstances, including but not limited to system incidents, market disruptions, or regulatory requirements. OKX will notify users as soon as reasonably practicable in such cases.
