OKX to Adjust SNDK Spot, Perpetual Futures and X-Perp Products Due to Stock Split

Published on Nov 9, 20266 min read

This is a general update. Please check the availability of the listed token or product for your region in the app.

Sandisk Corporation (NASDAQ: SNDK) has announced an eight-for-one (8-for-1) forward stock split, with each share becoming eight shares. To keep the affected products aligned with the underlying post-split price, OKX will begin adjusting xSNDK spot holdings, SNDK perpetual futures and Xperp contracts at 01:00 (UTC) on November 20, 2026.

The stock split itself does not generate an additional investment return. Holdings or position quantities will increase by a factor of eight, while the corresponding price per unit will be scaled to one eighth of its pre-split level. Actual adjustment results are subject to applicable precision and settlement rules.

During the adjustment, order placement, amendment, cancellation and matching will be suspended for the affected products. Relevant liquidation processing will also be paused. Deposits, withdrawals and transfers of the affected asset may pause as well; please refer to platform notices for the applicable arrangements.

After adjustments and checks are complete, affected products will enter a Post-only phase lasting at least 10 minutes. During this phase, you can submit Post-only limit orders and amend or cancel existing Post-only orders. Market, IOC, FOK and regular limit orders will be rejected. New take-profit and stop-loss orders will also be unavailable.

Normal trading will resume after the Post-only phase ends; resumption does not require waiting for the U.S. stock market to open. Entering the Post-only phase does not mean normal order matching has resumed, and normal trading is not guaranteed to 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 according to the split ratio and the issuer's terms:

Item

Adjustment

Platform share units

Existing share units × 8

Corresponding underlying price per unit

Scaled to one eighth of the pre-split price

Actual adjustment result

Subject to applicable precision rules and reflected in account records

For example, 10 share units before the adjustment will theoretically become 80 share units afterward. The increase in units is accompanied by a proportional reduction in the price per unit and does not itself increase the value of the holding.

IV. Perpetual futures and Xperp position adjustments

Perpetual futures and Xperp contracts will 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, subject to 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; subsequently changes with market prices

Trading fees for system-generated adjustments

No trading fees for the system-generated position closure and reopening

Contract size, price tick size and quantity step size

Unchanged by the stock split itself

Funding frequency

The stock split itself does not change 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.

Following the adjustment, Mark Price will change under its normal calculation mechanism and will not remain fixed at the adjustment-time reference. Rounding differences will be handled through corporate action settlement and any necessary balance adjustments, using the settlement currency applicable to 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 retained

Partially filled orders

Only the unfilled remainder adjusted and reposted with a new order ID

Orders that fail precision or other trading checks

Canceled; not retained 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 resume 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 be rewritten because of the stock split.

VI. Important reminders

  1. Manage positions and orders in advance.

    Complete any intended position changes or cancellations before the pause. You will not be able to cancel orders during the adjustment.

  2. Recreate take-profit and stop-loss orders.

    Canceled protective orders will not be automatically restored. Recreate them after normal trading resumes using the adjusted prices and quantities.

  3. Manually resume grid trading bots.

    Grid trading bots will be paused during the adjustment and will not resume automatically. After normal trading resumes, review their settings and associated orders, then manually resume the bots.

  4. Review the adjustment results.

    Check spot share units, contract positions, entry prices, realized P&L and resting orders.

  5. Monitor margin requirements.

    Once relevant liquidation processing resumes, risk will be assessed using the adjusted prices, positions and balances. Position reductions or liquidation may occur if margin requirements are not met.

  6. Synchronize API records.

    Before restarting strategies, synchronize orders, positions and balances. Note that reposted remainders of partially filled orders will have new order IDs.

For more information, please refer to the Corporate Actions Handling Mechanism and monitor subsequent platform notices.
