When you click on any options series, an advanced order form will pop up.
All orders are registered in the matching engine with prices in BTC. But it is possible for anybody to submit also volatility orders and orders that trail a fixed price in USD.
You can select the type of order you would like to submit. When you fill the orderform, you will always see the price in BTC, in USD, and the implied volatility corresponding with the price.
Our sophisticated price engine, in case of volatility orders or fixed price USD orders, will continuously update your order, such that the price of your order corresponds with the implied volatility or USD amount entered.
For calculations, the last deribit BTC index is used, so every 6 seconds the system will evaluate if your order needs to be adjusted or not.
