I've only partly found it though, I can't see in options tables with strike prices etc, does anyone know where they are?
Are you talking about the order book? Well, you won't find it like that on FTX. FTX Options don't work on orderbook model, instead they work on 'Request for Quote' (RFQ) model. So, you will see something like the following image on Options page:
You can click 'Request Quote' and place your order. You can manually customize your order - Put/Call, Strike Price, Expiry Date, Limit Price and Buy/Sell. Then, your request will go under 'My Request' section and within few seconds, you will start seeing quotes from the other users under 'Best Quote (per contract)' column. It's up to you if you want to accept those quotes or let them go.
For example, If I place request for the Buy Call Option of 1 BTC at the strike price of $48K for tomorrow midnight, I will start receiving quotes after few seconds under 'My Request' section. Suppose, I get the quote of $400. I can accept that and have to pay $400 for the option upfront. Then, if bitcoin goes above $48,400 at the midnight tomorrow, I will end up in profit otherwise I will bear the loss (could be between $1-400).
Alternatively, you can make quotes for the requests others have placed under 'All Requests' section if you see any. But note- you will play opposite party as to 'Option Type', consider that while making quote.
