	subaccountId satypes.SubaccountId,
) (bool, error)

CanDeleverageSubaccount returns true if a subaccount can be deleveraged. Specifically, this function returns true if both of the following are true: - The subaccount's total net collateral is negative. This function returns an error if `GetNetCollateralAndMarginRequirements` returns an error.

func (Keeper) CancelShortTermOrder 

func (k Keeper) CancelShortTermOrder(
	ctx sdk.Context,
	msgCancelOrder *types.MsgCancelOrder,
) error

CancelShortTermOrder removes a Short-Term order by `OrderId` (if it exists) from all order-related data structures in the memclob. As well, CancelShortTermOrder adds (or updates) a cancel to the desired `goodTilBlock` in the memclob. If a cancel already exists for this order with a lower `goodTilBlock`, the cancel is updated to the new `goodTilBlock`. This method is meant to be used in the CheckTx flow. It uses the next block height.

An error will be returned if any of the following conditions are true: - The cancel's `GoodTilblock` is less than or equal to the next block height. - The cancel's `GoodTilblock` is greater than the sum of the next block height and `ShortBlockWindow`. - The memclob itself returns an error.

This method assumes the provided MsgCancelOrder has already passed ValidateBasic in CheckTx.

func (Keeper) CancelStatefulOrder 

func (k Keeper) CancelStatefulOrder(
	ctx sdk.Context,
	msg *types.MsgCancelOrder,
) (err error)

The following conditions must be true otherwise an error will be returned:

  • Stateful Order Cancellation cancels an existing stateful order.
  • Stateful Order Cancellation GTBT is greater than or equal to than stateful order GTBT.
  • Stateful Order Cancellation GTBT is greater than the block time of previous block.
  • Stateful Order Cancellation GTBT is less than or equal to `StatefulOrderTimeWindow` away from block time of previous block.

Note that this method conditionally updates state depending on the context. This is needed to separate updating committed state during DeliverTx (the stateful order and the ToBeCommitted stateful order count) from uncommitted state that is modified during CheckTx.

)

ConvertFillablePriceToSubticks converts the fillable price of a liquidation order to subticks. The returned subticks will be rounded to the nearest tick (such that `subticks % clobPair.SubticksPerTick == 0`). This function will round up for sells that close longs, and round down for buys that close shorts.

Note the returned `subticks` will be bounded (inclusive) between `clobPair.SubticksPerTick` and `math.MaxUint64 - math.MaxUint64 % clobPair.SubticksPerTick` (the maximum `uint64` that is a multiple of `clobPair.SubticksPerTick`).

) (types.ClobPair, error)

CreatePerpetualClobPair creates a new perpetual CLOB pair in the store. Additionally, it creates an order book matching the ID of the newly created CLOB pair.

An error will occur if any of the fields fail validation (see validateClobPair for details), or if the `perpetualId` cannot be found. In the event of an error, the store will not be updated nor will a matching order book be created.

Returns the newly created CLOB pair and an error if one occurs.

func (Keeper) DeleteLongTermOrderPlacement 

func (k Keeper) DeleteLongTermOrderPlacement(
	ctx sdk.Context,

	offchainUpdates *types.OffchainUpdates,
	err error,
)

ProcessSingleMatch accepts a single match and its associated orders matched in the block, persists the resulting subaccount updates and state fill amounts. This function assumes that the provided match with orders has undergone stateless validations. If additional validation of the provided orders or match fails, an error is returned. The following validation occurs in this method:

  • Order is for a valid ClobPair.
  • Order is for a valid Perpetual.
  • Validate the `fillAmount` of a match is divisible by the `ClobPair`'s `StepBaseQuantums`.
  • Validate the new total fill amount of an order does not exceed the total quantums of the order given the fill amounts present in the provided `matchOrders` and in state.
  • Validate the subaccount updates resulting from the match are valid (before persisting the updates to state)
  • For liquidation orders, stateful validations through calling `validateMatchPerpetualLiquidationAgainstSubaccountBlockLimits`.
  • Validating that deleveraging is not required for processing liquidation orders.

This method returns `takerUpdateResult` and `makerUpdateResult` which can be used to determine whether the maker and/or taker failed collateralization checks. This information is particularly pertinent for the `memclob` which calls this method during matching. TODO(DEC-1282): Remove redundant checks from `ProcessSingleMatch` for matching. This method mutates matchWithOrders by setting the fee fields.

func (k Keeper) RemoveExpiredStatefulOrdersTimeSlices(ctx sdk.Context, blockTime time.Time) (
	expiredOrderIds []types.OrderId,
)

RemoveExpiredStatefulOrdersTimeSlices iterates all time slices from 0 until the time specified by `blockTime` (inclusive) and removes the time slices from state. It returns all order IDs that were removed.

func (Keeper) RemoveOrderFillAmount 

func (k Keeper) RemoveOrderFillAmount(ctx sdk.Context, orderId types.OrderId)

RemoveOrderFillAmount removes the fill amount of an Order from state and the memstore. This function is a no-op if no order fill amount exists in state and the mem store with `orderId`.

func (Keeper) ReplayPlaceOrder 

func (k Keeper) ReplayPlaceOrder(
	ctx sdk.Context,
	msg *types.MsgPlaceOrder,
) (
	orderSizeOptimisticallyFilledFromMatchingQuantums satypes.BaseQuantums,
	orderStatus types.OrderStatus,
	offchainUpdates *types.OffchainUpdates,
	err error,
)

ReplayPlaceOrder returns the result of calling `PlaceOrder` on the memclob. This method does not forward events directly to indexer, but instead returns them in the form of `OffchainUpdates`. This method is meant to be used in the `ReplayOperations` flow, where we replay Short-Term and newly-played stateful orders back onto the memclob.

An error will be returned if any of the following conditions are true: - Standard stateful validation fails. - The memclob itself returns an error.

func (Keeper) SendOffchainMessages 

func (k Keeper) SendOffchainMessages(
	offchainUpdates *types.OffchainUpdates,
	additionalHeaders []msgsender.MessageHeader,
	metric string,
)

SendOffchainMessages sends all the `Message` in the offchainUpdates passed in along with any additional headers passed in. No headers will be added if a `nil` or empty list of additional headers is passed in.

func (*Keeper) SetAnteHandler 

func (k *Keeper) SetAnteHandler(anteHandler sdk.AnteHandler)

Sets the ante handler after it has been constructed. This breaks a cycle between when the ante handler is constructed and when the clob keeper is constructed.

func (Keeper) SetClobPairIdForPerpetual 

func (k Keeper) SetClobPairIdForPerpetual(ctx sdk.Context, clobPair types.ClobPair)

SetClobPairIdForPerpetual sets the mapping between clob pair and perpetual.

func (Keeper) SetLongTermOrderPlacement 

func (k Keeper) SetLongTermOrderPlacement(
	ctx sdk.Context,
	order types.Order,
	blockHeight uint32,
)

SetLongTermOrderPlacement sets a stateful order in state, along with information about when it was placed. The placed order can either be a conditional order or a long term order. If the order is conditional, it will be placed into the Untriggered Conditional Orders state store. If it is a long term order, it will be placed in the Long Term Order state store. If the `OrderId` doesn't exist then the stateful order count is incremented. Note the following: - If a stateful order placement already exists in state with `order.OrderId`, this function will overwrite it. - The `TransactionIndex` field will be set to the next unused transaction index for this block. - Triggered conditional orders should use the `TriggerConditionalOrder` write path.

func (Keeper) SetOrderFillAmount 

func (k Keeper) SetOrderFillAmount(
	ctx sdk.Context,
	orderId types.OrderId,
	fillAmount satypes.BaseQuantums,
	prunableBlockHeight uint32,
)

SetOrderFillAmount writes the total `fillAmount` and `prunableBlockHeight` of an order to on-chain state. TODO(DEC-1219): Determine whether we should continue using `OrderFillState` proto for stateful orders.

func (Keeper) SetStatefulOrderCount 

func (k Keeper) SetStatefulOrderCount(
	ctx sdk.Context,
	subaccountId satypes.SubaccountId,
	count uint32,
)

SetStatefulOrderCount sets a count of how many stateful orders are written to state.

func (Keeper) SetUncommittedStatefulOrderCount 

func (k Keeper) SetUncommittedStatefulOrderCount(
	ctx sdk.Context,
	orderId types.OrderId,
	count int32,
)

SetUncommittedStatefulOrderCount sets a count of uncommitted stateful orders for the associated subaccount. This represents the number of stateful order `placements - cancellations` that this validator is aware of during `CheckTx`. Note that this value can be negative (for example if the stateful order is already on the book and the cancellation is uncommitted). OrderId can be conditional or long term.

func (Keeper) SortLiquidationOrders 

func (k Keeper) SortLiquidationOrders(
	ctx sdk.Context,
	liquidationOrders []types.LiquidationOrder,
)

SortLiquidationOrders deterministically sorts the liquidation orders in place. Orders are first ordered by their absolute percentage difference from the oracle price in descending order, followed by the their size in quote quantums in descending order, and finally by order hashes.

func (Keeper) UpdateClobPair 

func (k Keeper) UpdateClobPair(
	ctx sdk.Context,
	clobPair types.ClobPair,
) error

UpdateClobPair overwrites a ClobPair in state and sends an update to the indexer. This function returns an error if the update includes an unsupported transition for the ClobPair's status.

func (Keeper) UpdateLiquidationsConfig 

func (k Keeper) UpdateLiquidationsConfig(
	ctx sdk.Context,
	config types.LiquidationsConfig,
) error

UpdateLiquidationsConfig updates the liquidations config in state.

func (Keeper) UpdateSubaccountLiquidationInfo 

func (k Keeper) UpdateSubaccountLiquidationInfo(
	ctx sdk.Context,
	subaccountId satypes.SubaccountId,
	notionalLiquidatedQuoteQuantums *big.Int,
	insuranceFundDeltaQuoteQuantums *big.Int,
)

UpdateSubaccountLiquidationInfo updates the total notional liquidated and total insurance lost of the given subaccount for the current block.

func (Keeper) ValidateLiquidationOrderAgainstProposedLiquidation 

func (k Keeper) ValidateLiquidationOrderAgainstProposedLiquidation(
	ctx sdk.Context,
	order *types.LiquidationOrder,
	proposedMatch *types.MatchPerpetualLiquidation,
) error

ValidateLiquidationOrderAgainstProposedLiquidation performs stateless validation of a liquidation order against a proposed liquidation. An error is returned when

  • The CLOB pair IDs of the order and proposed liquidation do not match.
  • The perpetual IDs of the order and proposed liquidation do not match.
  • The total size of the order and proposed liquidation do not match.
  • The side of the order and proposed liquidation do not match.

func (Keeper) ValidateSubaccountEquityTierLimitForNewOrder 

func (k Keeper) ValidateSubaccountEquityTierLimitForNewOrder(ctx sdk.Context, order types.Order) error

ValidateSubaccountEquityTierLimitForNewOrder returns an error if adding the order would exceed the equity tier limit on how many open orders a subaccount can have. Short-term fill-or-kill and immediate-or-cancel orders never rest on the book and will always be allowed as they do not apply to the number of open orders that equity tier limits enforce.

Note that the method is dependent on whether we are executing on `checkState` or on `deliverState` for stateful orders. For `deliverState`, we sum:

  • the number of long term orders.
  • the number of triggered conditional orders.
  • the number of untriggered conditional orders.

And for `checkState`, we add to the above sum the number of uncommitted stateful orders in the mempool.

type MevTelemetryConfig 

type MevTelemetryConfig struct {
	Enabled    bool
	Hosts      []string
	Identifier string
}

type OrderIdFillState 

type OrderIdFillState struct {
	types.OrderFillState
	OrderId types.OrderId
}

OrderIdFillState is a struct that represents an order fill amount in state.

type PnLCalculationParams 

type PnLCalculationParams struct {
	// contains filtered or unexported fields
}

type UntriggeredConditionalOrders 

type UntriggeredConditionalOrders struct {
	// All untriggered take profit buy orders and stop loss sell orders sorted by time priority.
	// These orders will be triggered when the oracle price goes lower than or equal to the trigger price.
	// This array functions like a max heap.
	OrdersToTriggerWhenOraclePriceLTETriggerPrice []types.Order

	// All untriggered take profit sell orders and stop loss buy orders sorted by time priority.
	// These orders will be triggered when the oracle price goes greater than or equal to the trigger price.
	// This array functions like a min heap.
	OrdersToTriggerWhenOraclePriceGTETriggerPrice []types.Order
}

UntriggeredConditionalOrders is an in-memory struct stored on the clob Keeper. It is intended to efficiently store placed conditional orders and poll out triggered conditional orders on oracle price changes for a given ClobPairId. All orders contained in this data structure are placed conditional orders with the same ClobPairId and are untriggered, unexpired, and uncancelled. Note that we are using a Order list for the initial implementation, but for optimal runtime a an AVL-tree backed priority queue would work. TODO(CLOB-717) Change list to use priority queue.

func NewUntriggeredConditionalOrders 

func NewUntriggeredConditionalOrders() *UntriggeredConditionalOrders

func (*UntriggeredConditionalOrders) AddUntriggeredConditionalOrder 

func (untriggeredOrders *UntriggeredConditionalOrders) AddUntriggeredConditionalOrder(order types.Order)

AddUntriggeredConditionalOrder adds an untriggered conditional order to the UntriggeredConditionalOrders data structure. It will panic if the order is not a conditional order.

func (*UntriggeredConditionalOrders) IsEmpty 

func (untriggeredOrders *UntriggeredConditionalOrders) IsEmpty() bool

IsEmpty returns true if the UntriggeredConditionalOrders' order slices are both empty.

func (*UntriggeredConditionalOrders) PollTriggeredConditionalOrders 

func (untriggeredOrders *UntriggeredConditionalOrders) PollTriggeredConditionalOrders(
	oraclePriceSubticksRat *big.Rat,
) []types.OrderId

PollTriggeredConditionalOrders removes all triggered conditional orders from the `UntriggeredConditionalOrders` struct given a new oracle price for a clobPairId. It returns a list of order ids that were triggered. This is only called in EndBlocker. We round up to the nearest subtick int for LTE and down to the nearest subtick int for GTE conditions. This is pessimistic rounding, as we want to trigger orders only when we are sure they are triggerable.

func (*UntriggeredConditionalOrders) RemoveUntriggeredConditionalOrders 

func (untriggeredOrders *UntriggeredConditionalOrders) RemoveUntriggeredConditionalOrders(
	orderIdsToRemove []types.OrderId,
)

RemoveUntriggeredConditionalOrders removes a list of order ids from the `UntriggeredConditionalOrders` data structure. This function will panic if the order ids contained involve more than one ClobPairId.
