This is a general update. Please check if the listed token or product is available in your region using the app.

Sandisk Corporation (NASDAQ: SNDK) has announced an eight-for-one (8-for-1) forward stock split. Each share will become eight shares. To adjust for this change, OKX will modify xSNDK spot holdings, SNDK perpetual futures, and Xperp contracts starting at 01:00 (UTC) on November 20, 2026.

The stock split does not create extra investment returns. Holdings or position quantities will increase by eight times, while the price per unit will be reduced to one eighth of its pre-split value. Actual adjustment results will follow applicable precision and settlement rules.

II. Affected products and trading details

Product	Affected trading pair / contract (instrument ID)	Adjustment start time
Spot	XSNDK-USDT	November 20, 2026, 01:00 (UTC)
Spot	XSNDK-USDC	November 20, 2026, 01:00 (UTC)

During the adjustment, you will not be able to place, change, cancel, or match orders for the affected products. Liquidation processing will also be paused. Deposits, withdrawals, and transfers of the affected asset may also be paused; please check platform notices for specific arrangements.

After the adjustments are complete, affected products will enter a Post-only phase lasting at least 10 minutes. In this phase, you can submit Post-only limit orders and change or cancel existing Post-only orders. Market, IOC, FOK, and regular limit orders will be rejected. New take-profit and stop-loss orders will not be available.

Normal trading will start again after the Post-only phase ends; you do not have to wait for the U.S. stock market to open. Entering the Post-only phase does not mean normal order matching has resumed, and normal trading may not resume after 10 minutes. Please check the actual instrument status and platform notices for the resumption time. Asset transfers, normal trading, index components, and price limits may resume at different times.

III. Spot holding adjustments

xSNDK spot share units will be adjusted based on the split ratio and issuer's terms:

Item	Adjustment
Platform share units	Existing share units × 8
Price per unit	Reduced to one eighth of the pre-split price
Actual adjustment result	Subject to applicable precision rules and shown in account records

For instance, 10 share units before the adjustment will become 80 share units afterward. The increase in units comes with a proportional decrease in price per unit and does not increase the total value of the holding.

IV. Perpetual futures and Xperp position adjustments

Perpetual futures and Xperp contracts will also follow the same stock split adjustment process. The system will first settle the old position at the pre-adjustment Mark Price, converting unrealized P&L into realized P&L. A new position will then be opened at the adjusted Mark Price.

Item	Adjustment
Position quantity	Existing position quantity × 8, following existing quantity precision rules
Index Price / Mark Price adjustment references	Each pre-adjustment price snapshot divided by eight
New average entry price	Post-adjustment Mark Price
Unrealized P&L on the old position	Settled as realized P&L
Unrealized P&L on the new position	Zero at the adjusted settlement reference; will change with market prices
Trading fees for system-generated adjustments	No trading fees for closing and reopening positions due to the system
Contract size, price tick size, and quantity step size	Remain unchanged by the stock split
Funding frequency	The stock split does not affect the normal funding frequency

The new entry price is the post-adjustment Mark Price, not the original entry price divided by eight. Previous P&L is settled as realized P&L; it does not disappear when unrealized P&L on the new position resets to zero.

After the adjustment, Mark Price will change according to its normal calculation method and will not stay fixed at the adjustment-time reference. Rounding differences will be managed through corporate action settlement and any necessary balance adjustments, using the settlement currency for each product.

V. Order handling

Order type / status	Treatment
Eligible regular limit and Post-only orders	Order price divided by eight; unfilled quantity multiplied by eight
Entirely unfilled orders	Price and quantity adjusted; original order ID kept
Partially filled orders	Only the unfilled part adjusted and reposted with a new order ID
Orders that fail precision or other trading checks	Canceled; not kept or reposted
Untriggered take-profit and stop-loss orders	Canceled and not automatically restored
Running grid trading bots	Paused during the adjustment; users must manually restart them after normal trading resumes
Other running strategies or bots	May pause; check their status after trading resumes

Adjusted buy prices will be rounded down and sell prices rounded up to the price tick size. Unfilled quantities will be rounded down to the quantity step size. If the resulting quantity is zero or below the minimum order size, the order will be canceled.

Completed historical fills will not change due to the stock split.

VI. Important reminders

Manage positions and orders in advance.
Complete any position changes or cancellations before the pause. You cannot cancel orders during the adjustment.
Recreate take-profit and stop-loss orders.
Canceled protective orders will not be restored automatically. Recreate them after normal trading resumes using the adjusted prices and quantities.
Manually resume grid trading bots.
Grid trading bots will pause during the adjustment and will not restart automatically. After normal trading resumes, check their settings and associated orders, then manually restart the bots.
Review the adjustment results.
Check spot share units, contract positions, entry prices, realized P&L, and resting orders.
Monitor margin requirements.
Once liquidation processing resumes, risk will be assessed using adjusted prices, positions, and balances. Position reductions or liquidation may happen if margin requirements are not met.
Synchronize API records.
Before restarting strategies, synchronize orders, positions, and balances. Note that reposted parts of partially filled orders will have new order IDs.

For more information, please refer to the Corporate Actions Handling Mechanism and keep an eye on future platform notices.
