OKX to list bi-monthly and bi-quarterly USDT and crypto-margined futures for BTC

Dear OKX users,

To improve market liquidity and offer more trading opportunities, OKX will adjust the expiration date rules for BTC/USDT- and BTC/USD-margined futures contracts. Starting at 8:00 am UTC on November 17, 2023, we are expanding the available durations for BTC/USDT- and BTC/USD-margined futures contracts to the following: weekly, bi-weekly, monthly, bi-monthly, quarterly, and bi-quarterly. Currently, we only support the following 4 durations: weekly, bi-weekly, quarterly, and bi-quarterly.
Starting from 8:00 am UTC on November 2, 2023, and lasting until 8:00 am UTC on November 8, 2023, the names of all futures contracts will progressively display their respective expiration dates.
The names of all futures contracts in the API services are exempt from this new display rule. New enumeration values, “this_month” and “next_month”, will be added to the alias field in the API’s returned parameters. For more details, please visit here.

The adjustment details are as follows:

1. BTC/USDT and BTC/USD futures generation

Following this adjustment, all the available expiration dates for newly listed contracts will be as follows:
