Dear OKX customers:


To improve market liquidity and optimize customer trading experience, OKX will adjust the contract multiplier of ETHUSD options on July 07, 2022, 09:10 AM (UTC) and BTCUSD options on July 14, 2022, 09:10 AM (UTC), respectively. The detailed adjustments are as follows:

Adjustment Time (UTC)
July 07, 2022, 09:10 AM
July 14, 2022, 09:10 AM
Before adjustment
After adjustment

After this adjustment:

The number of contract of current orders, historical orders (including Limit Order and Strategy Order) and positions will change accordingly based on the change of the contract multiplier. Before and after the change, the value of the trading currency unit remains unchanged for all positions and orders. That is, for a position valued 1 BTC (10 x 0.1), the adjusted position value is still 1 BTC (100 x 0.01).

Example 1: Assume you have 10 pending orders on -ETHUSD-0627-3000C options. When the multiplier of ETHUSD option contract is adjusted from 1 to 0.1, the pending contract number will be adjusted to 100.

Example 2: Assume you have 30 option contracts of +BTCUSD-0627-30000C in current position. When the multiplier of BTCUSD option contract is adjusted from 0.1 to 0.01, the contract number will be adjusted to 300.


Please adjust your trading strategy in time according to the adjustments rules. We apologize for any inconvenience caused by this change.
