OKX Launches Hit and Between Event Contract Types

Published on Jul 6, 20263 min read

Dear OKX Users,OKX will officially launch two new event contract types，further expanding the trading capabilities of Event Contract.

  • Hit and Between，initially support BTC, ETH underlyings— on July 7, 2026 (UTC+8)

  • Hit and Between，support XAU underlying — on July 14, 2026 (UTC+8),

The update will apply to the Web, App, and API interfaces. Details are as follows:

I. Hit Event Contract

Hit contracts follow a "touch-and-settle" mechanism — during the contract's life, once the OKX official index reaches the target price, the contract immediately settles as "Yes" without waiting for expiry.

Item

Description

Settlement anchor

OKX official index (real-time, per-second monitoring)

Hit-Up (target above)

Index ≥ target price → settles as "Yes"

Hit-Down (target below)

Index ≤ target price → settles as "Yes"

Not touched by expiry

Contract settles as "No" at expiry

Settlement price

Official index price at the trigger moment

Supported frequencies

Daily, Monthly

Touch determination: A touch is registered when the per-second index high or low meets the trigger condition. No minimum price duration is required.

Ordering note: The contract may still be tradeable between the touch and settlement. Do not rely solely on tradeability to determine whether a touch has occurred — verify whether the target has already been touched before placing an order.

II. Between Event Contract

Between contracts predict whether the settlement price will fall within a specified price range at expiry, suitable for range-bound market conditions.

Item

Description

Settlement anchor

OKX official index

Settlement price

Arithmetic mean of per-second official index prices over the 1-minute window before expiry

Evaluation point

Evaluated once at expiry

Range determination

With lower bound a and upper bound b (a < b): a ≤ settlement price < b → "Yes"; otherwise → "No"

Boundaries

Left-closed, right-open: lower bound is included, upper bound is excluded

Supported frequencies

Daily

Important: Between contracts do not support early settlement. Price excursions during the contract's life do not affect the outcome — only the settlement price at expiry is used.

III. XAU (Gold) Underlying — Special Notes

Both Hit and Between contracts on XAU use the OKX XAU-USDT index as the settlement benchmark, subject to the following rules:

  • Non-Trading Days: OKX references the XCEC Holiday Calendar and relevant trading-hours metadata. Where the scheduled expiry of an XAU contract falls on a known non-trading day, the contract will not be listed.

  • Trading Hours (Hit contracts): Touch determination and settlement for XAU Hit contracts are performed only when the underlying TradFi market is tradeable and index prices are available. Weekends and daily closure windows are excluded from touch evaluation.

  • Market Disruption: If an unscheduled trading halt, early close, stale price, or other underlying market disruption occurs, the event enters dispute review and OKX determines the final settlement price under the manual settlement procedure.
