OKX to launch limit orders for options based on IV/USD price

To enhance the functionalities offered to options traders, OKX will launch limit orders for options based on implied volatility (IV) and USD price at 2:00 pm UTC 8 on September 8, 2023.
This feature will first be launched on the OKX website. It will be available on the OKX app at a later date, which will be announced accordingly.

Limit orders based on IV

You can place a limit order with an IV value to specify the target price level of your options contract. The BTC/ETH prices of these orders are continuously updated using the Black-Scholes (BS) options pricing formula once they're placed in the order book, such that the corresponding IVs of the orders remain close to the levels you specify. The BTC/ETH prices of these orders are updated every 3 seconds in the order book.

Limit orders based on USD price

You can place a limit order with a USD price to specify the target price level of your options contract. The BTC/ETH prices of these orders are continuously updated using the prevailing crypto index price once they're placed in the order book, such that the corresponding USD prices of the orders remain close to the level you specify. The BTC/ETH prices of these orders are updated every 3 seconds in the order book.

Currency adjustment for options trading

We have also adjusted the currency used in options trading:

• Options prices and order/position amounts are no longer displayed in the local currency you select. These fields are only displayed in crypto or USD.
• The BTC/ETH price index used as the underlying index for options contracts is no longer displayed in the local currency you select. Only the USD index of BTC/ETH is displayed.

How to place limit orders based on IV/USD price

Check the "Tracking orders" box on the limit order UI for options to place a limit order based on IV or USD price. You can still place limit orders for options using prices specified in crypto (BTC/ETH).
