Users can manage their Position Assignment Programme (PAS) preferences via the Settings > Derivatives PAS tab on the Kraken Pro UI.
From here, clients must agree that they understand PAS and the risks involved. Once the client has confirmed they understand the PAS they can set the preferences via the UI or the API. Preferences changes are limited on a per contract pair basis.
The client must choose the contract pair, whether to accept long or short positions (or both), the max size, the max position per contract after assignment and the timeframe (weekends, weekdays, all).
There are optional preferences such as global position size, minimum profitability*, and maximum effective leverage*.
Active preferences will show at the top of the page, with the preference history showing below.
Preferences can also be edited by clicking the edit icon on the right hand side of the row.
Clients can also delete a preference if they no longer wish to take part in the PAS. This will then create a new entry in the preference history.
