Crate rustrade_execution 

Barter-Execution

Stream private account data from financial venues, and execute (live or mock) orders. Also provides a feature rich MockExchange and MockExecutionClient to assist with backtesting and paper-trading.

It is:

• Easy: ExecutionClient trait provides a unified and simple language for interacting with exchanges.
• Normalised: Allow your strategy to communicate with every real or MockExchange using the same interface.
• Extensible: Barter-Execution is highly extensible, making it easy to contribute by adding new exchange integrations!

See README.md for more information and examples.

Modules

balance

borrow_capacity

How much more this account can borrow now: what a venue says about the account’s own capacity to borrow, as opposed to Shortability, which says what the venue has to lend.

cash_flow

Cash that moves into or out of an account other than by a trade: perpetual funding, margin interest, stock borrow fees and rebates.

client

Execution client implementations for various exchanges.

error

Error types for ExecutionClient operations.

exchange

fee

fill

fill_recovery

What an account stream reports when its fill recovery gives up on a span of fills.

holding_cost

What a simulated position costs to hold over time: perpetual funding, borrow fees and overnight financing.

indexer

map

margin

Margin borrowing: the borrow and repay policy a margin account applies to its orders, the simulated venue’s spot margin configuration, and the interest it charges on its loans.

margin_debt

A change in what a margin account owes in one asset, as the venue streams it: a borrow, a repay or an interest charge.

market

notice

Notices a venue sends about an account’s state that are not trades, orders or balances: margin calls, liquidation warnings, a liquidation under way, and the all-clear after them.

order

position

reduce_only

Which of an instrument’s orders were sent reduce-only, kept so a fill can be matched to the ReduceOnly of its order.

rules

An instrument’s order rules (tick, lot step, minimums and maximums) and the check of an order against them before it is sent.

shortability

Whether an instrument can be sold short, and on what terms: what a venue says about lending it.

slippage

Adverse slippage on the simulated venue’s taker fills.

trade

Structs

AccountEvent

AccountSnapshot

InstrumentAccountSnapshot

One instrument’s slice of an AccountSnapshot: its orders, and its position or isolated balances where the venue has them.

InstrumentBalanceSnapshot

One asset’s full balance in a pair’s isolated sub-account, debt included (the AccountEventKind::InstrumentBalanceSnapshot payload).

InstrumentBalanceUpdate

Live per-instrument isolated-margin balance update payload (the AccountEventKind::InstrumentBalanceUpdate counterpart of IsolatedInstrumentState).

IsolatedInstrumentState

Per-pair isolated-margin state attached to an InstrumentAccountSnapshot.

IsolatedMarginRisk

Per-pair isolated-margin risk metrics, surfaced on IsolatedInstrumentState.
