Order Cancel/Replace Request(G) — Production FIX API - Deribit API Documentation

To change/edit the parameters of an existing order. From Release 1.3.10, it is possible to amend an order by ClOrdID or DeribitLabel, and OrigClOrdId is not required anymore, however amending orders by OrigClOrdId is noticeably faster.

IMPORTANT:

to change the order using ClOrdID or DeribitLabel, this must be the only existing order with such ClOrdID or DeribitLabel. Multiple orders with the same ClOrdID or DeribitLabel won’t be amended that way.
when possible it is recommended to use faster OrigClOrdId

On spot instruments matched on Coinbase Exchange, ExecInst(18) accepts only 6A and DisplayQty(1138) is rejected. See Spot trading venues.

A grapheme cluster is a user-perceived character, which can be represented by several unicode codepoints. Please refer to Unicode specification for more details about the grapheme clusters
41	`OrigClOrdId`	String	Required if `DeribitLabel`, `ClOrdID` are absent	Order identifier assigned by Deribit over the user one
100010	`DeribitLabel`	String	Required if `OrigClOrdId`, `ClOrdID` are absent	A custom label for your order, max 64 grapheme clusters. Can be used by `Order Cancel Request`(`F`) to amend the order later on

62	`ValidUntilTime`	UTCTimestamp	No	Indicates expiration time of indication message, in UTC
15	`Currency`	String	No	To speed up the search of the order by `DeribitLabel` or `ClOrdID`
54	`Side`	char	Yes	Should match the original order’s side. Valid values: `1` = Buy, `2` = Sell
38	`OrderQty`	Qty	Yes	Order quantity. Depends on `QtyType`. When `QtyType` is set to `Units`, the `OrderQty` is specified in USD for perpetual and inverse futures, in the underlying base currency coin for linear futures, or in the amount of cryptocurrency contracts for options. The system will automatically convert `Units` to `Contracts` when the order is placed Please, note that Quantity is by default defined in Contract units corresponding to the ContractMultiplier in SecurityList
40	`OrdType`	char	No	Currently `2` - ‘limit’
44	`Price`	Price	No	Order price (for advanced options orders it could be volatility or USD value if applicable)
18	`ExecInst`	MultipleCharValue	No	Currently is used to mark POST ONLY orders and REDUCE ONLY orders. POST ONLY valid values: `6` = “Participate don’t initiate”, `A` = “No cross” (only together with 6, “`6A`” — REJECT POST ONLY when the order is put to the order book unmodified or the request is rejected and order is cancelled), REDUCE ONLY valid values: `E` = ” Do not increase - DNI”
854	`QtyType`	Int	No	Type of quantity. Valid values: `0` = `Units`, `1` = `Contracts` Default is `Contracts`. When `QtyType` is `Units`, then for perpetual and inverse futures the `OrderQty` is in USD units, and for linear futures it is the underlying base currency coin, and for options it is the amount of corresponding cryptocurrency (e.g., BTC or ETH). The `Units` will be recalculated into the system’s `Contracts` on server automatically when the order is placed.
1138	`DisplayQty`	Qty	No	The (max) quantity to be displayed in the orderbook.
9008	`DeribitMMProtection`	Boolean	No	Order Market Maker Protection (MMP) flag, if it is absent then the current MMP flag of the order is not changed. `N` removes the flag if it is set. Important: manual admin action is necessary to activate Market Maker Protection (MMP) for an account
