Trailing Stop loss
Deribit will enable a new type of stop-loss order; a trailing stop loss is a type of order that enables the client to set a max drop from the high of a certain instrument measured in Dollars for inverse instruments and USDC for linear instruments. The stop can be triggered by the same triggers as our other triggers (index price, mark price or last price). If the price of the underlying instrument moves in favor of the client, the stop order trigger level will move up accordingly. Once the instrument price falls by the maximum offset value (trigger_offset), the position gets stopped-out.
Valid until order parameter
We have added a new valid_until parameter with timestamp to all private/buy, private/sell, private/edit and private/edit_by_label requests. Those requests will in that case only be executed only if the current server timestamp is lower than provided when the request reaches the book. If the request cant be processed in time a timed_outerror will be sent.
This feature will not be made available from the UI.
RFQ - Request For Quote
A new /private/send_rfq request has been added which sends a notification to market makers or anyone subscribing to rfq.{currency} notification channel or requesting RFQs via /public/get_rfqs The RFQ request is rate limited to 10 per 3 days. Amount and side (buy / sell) are non-compulsory fields.
This feature will also soon be available from the UI.
