ACE API Spec v1.0.5

This document provides specifications for connecting to the Archax Complete Ecosystem (ACE) API endpoints. We provide two APIs - HTTP REST and WebSockets. For detailed information about each API visit the REST API and WebSocket API sections.

REST API

The Archax REST API allows developers to retrieve authentication tokens and instrument information. All resources are defined under the following URL:

https://ace-auth.archax.com/api/1.0

All responses from the REST API are wrapped inside this response wrapper

WebSocket API

The Archax WebSocket API allows developers to subscribe to real-time market data feeds.

Additionally, the API accepts commands for the creation and cancellation of orders.

Connection

Login command

{
  "action": "login",
  "service": "core",
  "token": "valid-token"
}

Successful login event

{
  "action": "user-login-success",
  "data": [],
  "description": "Authorisation successful",
  "status": "OK",
  "type": "user-login"
}

Failed login event

{
  "action": "user-login-failed",
  "data": [],
  "description": "Authorisation failed",
  "status": "ERROR",
  "type": "user-login"
}

The public WebSocket endpoint is wss://ace-auth.archax.com/api/1.0/gateway.

To login to the API you must obtain a JWT token from the REST login endpoint. In combination with the JWT, you must specify the login action and the core service.

Once your login credentials have been verified, you will receive a user-login-success event. Otherwise you will receive a user-login-failed event and you will then be disconnected.

Send a subscribe-market-quotes command to subscribe to real-time pricing updates for all instruments available in the market. It initially returns a set-market-quotes event that includes the market quotes for each instrument. Subsequent events only contain updates for the included fields.

Each value in the data property is keyed by instrumentId.

Set Market Quotes Event Schema

Name	Type	Description
[key]		Identifier of the asset
askPrice	string	Best asking price for the asset
askQty	string	Number of units on offer at the `askPrice`
bidPrice	string	Best bid price for the asset
bidQty	string	Number of units requested at the `bidPrice`
changePercent	string	The percentage difference between the `lastPrice` and `closePrice`
changePrice	string	The difference between the `lastPrice` and `closePrice`
closePrice	string	The asset’s last traded price from the previous trading session
cumulativeUnits	string	The cumulative volume of units traded within the current trading session
cumulativeValue	string	The cumulative value of all trades on the asset for the current trading session
instrumentId	number	Unique identifier of the asset
lastPrice	string	Last traded price for the asset
highPrice	string	Highest trade price for the asset during the current trading session
lowPrice	string	Lowest trade price for the asset during the current trading session
lastQty	string	Last traded quantity for the asset
openPrice	string	Price at which the first execution of the day for the asset occurred
sevenDayChange	string	The difference between `closePrice` and `sevenDayClosePrice`
sevenDayChangePercentage	string	The percentage difference between the `closePrice` and `sevenDayClosePrice`
sevenDayClosePrice	string	The asset’s close price 7 days prior

askPrice, bidPrice, changePrice, closePrice, cumulativeValue, highPrice, lastPrice, lowPrice, openPrice, sevenDayChange and sevenDayClosePrice would always be returned as a whole number. The number of decimal places for each asset then determines how these price values are formatted. Use the decimals property returned by the set-instruments event to determine the number of decimal places for the value in these fields.

If the value returned for askPrice is 2356 and the asset’s decimals property is 3. The actual askPrice is then obtained by evaluating: 2356 / (10 ^ 3) which gives 2.356. The same goes for all properties that end with Price.

askQty, bidQty, cumulativeUnits and lastQty would also always be returned as a whole number. To determine the number of decimal places, use the quantityDecimalPlaces property returned by the set-instruments event.

The set-market-quotes event would be returned each time there’s a change on any of the fields listed in the preceding table. The data property would only contain the fields that have changed. So, if you have an instrument with the following state:

"2": { "askPrice": "", "askQty": "", "bidPrice": "", "bidQty": "", "changePercent": "-24.19", "changePrice": "-4112.00", "closePrice": "17000", "cumulativeUnits": "", "cumulativeValue": "", "highPrice": "12888", "instrumentId": 2, "lastPrice": "12888", "lastQty": "3", "lowPrice": "12888", "openPrice": "", "sevenDayChange": "867.00", "sevenDayChangePercentage": "7.21", "sevenDayClosePrice": "12021" }

and you receive an update with following data:

{ "2": { "askQty": "35", } }

the expected state of instrumentId 2 is:

"2": { "askPrice": "", "askQty": "35", "bidPrice": "", "bidQty": "", "changePercent": "-24.19", "changePrice": "-4112.00", "closePrice": "17000", "cumulativeUnits": "", "cumulativeValue": "", "highPrice": "12888", "instrumentId": 2, "lastPrice": "12888", "lastQty": "3", "lowPrice": "12888", "openPrice": "", "sevenDayChange": "867.00", "sevenDayChangePercentage": "7.21", "sevenDayClosePrice": "12021" }

At the start of a trading session, a set-market-quotes event would be returned and the content of its data property would be similar to:

"2": { "askPrice": "", "askQty": "", "bidPrice": "", "bidQty": "", "changePercent": "0.00", "changePrice": "0", "cumulativeUnits": "", "cumulativeValue": "", "highPrice": "", "lowPrice": "", "openPrice": "" }

the expected state of instrumentId 2 would then be:

"2": { "askPrice": "", "askQty": "", "bidPrice": "", "bidQty": "", "changePercent": "0.00", "changePrice": "0", "closePrice": "17000", "cumulativeUnits": "", "cumulativeValue": "", "highPrice": "", "instrumentId": 2, "lastPrice": "12888", "lastQty": "3", "lowPrice": "", "openPrice": "", "sevenDayChange": "867.00", "sevenDayChangePercentage": "7.21", "sevenDayClosePrice": "12021" }

Send a subscribe-orders command to subscribe to order updates for the organisation you belong to. It initially returns a set-orders event that includes all orders. Subsequent set-orders events will only contain orders that have since been updated. The data property will be an object keyed by order id, with the following details:

Set Orders Event Schema

[key]		Unique order identifier
averagePrice	string	Average execution price for the order
created	string	Timestamp on when the order was placed (ms)
currency	string	Currency code
commission	string	Total commission value of the order
decimals	number	Number of decimal places of price figures of order instrument
executions	Execution	Details of executed trades, keyed by `id` (where `id` is a unique reference to the execution)
filledPercent	string	Filled percent
filledQty	string	Filled quantity without consideration of decimal places value (decimal places defined in `quantityDecimalPlaces` from Instruments Schema)
filledStatus	string	Fill status, possible values: `unfilled`, `partiallyFilled`, `filled`

side	string	Order side, possible values: `buy`, `sell`
symbol	string	Ticker symbol of instrument
type	string	Order type, possible values: `limit`
tax	string	Total tax value of the order
userId	number	Unique identifier of the user

Execution Schema

Name	Type	Description
commission	string	Total commission value of the execution
created	string	Timestamp on when the trade was executed (ms)
grossExecutionAmount	string	Product of executed price and quantity
price	string	Executed price
id	string	Unique identifier to execution
quantity	string	Executed quantity without consideration of decimal places value (decimal places defined in `quantityDecimalPlaces` from Instruments Schema)
tax	string	Total tax value of the order

set-orders updates must be deeply merged from the previous state. For example, if an order has the following state:

{ "1626077181607120": { "orderStatus": "pending", "decimals": 2, "instrumentId": 3, "filledPercent": "0.00", "created": 1626077181607.12, "quantity": 100, "averagePrice": 0, "limitPrice": "35699", "currency": "USD", "filledQty": "0", "filledStatus": "unfilled", "side": "buy", "symbol": "FAKe", "type": "limit", "executions": {}, "id": "1626077181607120" } }

and you receive an update with following data:

{ "1626077181607120": { "orderStatus": "open" } }

the expected state of order 1626077181607120 is:

{ "1626077181607120": { "orderStatus": "open", "decimals": 2, "instrumentId": 3, "filledPercent": "0.00", "created": 1626077181607.12, "quantity": 100, "averagePrice": 0, "limitPrice": "35699", "currency": "USD", "filledQty": 0, "filledStatus": "unfilled", "side": "buy", "symbol": "FAKe", "type": "limit", "executions": {}, "id": "1626077181607120" } }

Send an order-cancel command to cancel an order.

Order cancellation is only available for orders submitted by users within that organisation with a status of open. If the status of an order is one of cancelled, completed, expired or rejected, sending the order-cancel command would result in a cancel-rejected event being returned.

The successful cancellation of an order would cause an order-cancelled event to be returned while a cancel-failed event is returned when there are errors in the submitted order-cancel command.

Send a subscribe-market-depths command to subscribe to Order Book updates for all instruments available in the market. It initially returns a set-market-depths event that includes Order Book information for each instrument available in the market. Subsequent events only contain updates for affected sides and depths of an instrument. Each value in the data property is keyed by instrumentId, and values under each side of the market (buy or sell) are keyed by market depth (prices). Note that the two right most digits in all prices represent decimal places.

Set Market Depths Event Schema

Name	Type	Description
[key]		Identifier of the asset
buy	string	Market depth (price) for the buy side of the market
indicativePrice	string	(Provided during auction phase) The price at which the most executions would occur if the auction ended at the current time. Also referred to as the uncrossing price
indicativeVolume	string	(Provided during auction phase) The number of units that would exchange hands if the auction ended at the current time
instrumentId	number	Identifier of the asset
sell	string	Market depth (price) for the sell side of the market

Market Depth Schema (Buy or Sell)

Name	Type	Description
[key]		Market depth (price without consideration of decimal places value, decimal places defined in `decimals` from Instruments Schema)
[value]	number	Volume (quantity without consideration of decimal places value, decimal places defined in `quantityDecimalPlaces` from Instruments Schema)

set-market-depths updates must be deeply merged from the previous state. For example, if an instrument has the following state:

{ "1": { "buy": { "1200": 100, "1300": 50 }, "indicativePrice": "", "indicativeVolume": "", "instrumentId": 1, "sell": { "1310": 20, "1320": 50 } } }

and you receive an update with following data:

{ "1": { "buy": { "1100": 500 }, "instrumentId": 1, "sell": {} } }

the expected state of instrumentId 1 is:

{ "1": { "buy": { "1100": 500, "1200": 100, "1300": 50 }, "indicativePrice": "", "indicativeVolume": "", "instrumentId": 1, "sell": { "1310": 20, "1320": 50 } } }

set-market-depths updates with a quantity value of 0 are sent to clear a particular depth. For example, if an instrument has the following state:

{ "1": { "buy": { "1200": 100, "1300": 50 }, "indicativePrice": "", "indicativeVolume": "", "instrumentId": 1, "sell": { "1310": 20, "1320": 50 } } }

and you receive an update with following data:

{ "1": { "buy": { "1300": 0 }, "instrumentId": 1, "sell": {} } }

the expected state of instrumentId 1 is:

{ "1": { "buy": { "1200": 100 }, "indicativePrice": "", "indicativeVolume": "", "instrumentId": 1, "sell": { "1310": 20, "1320": 50 } } }

To subscribe to all trade histories, send a subscribe-trade-histories command. To subscribe to trade history for a specific instrumentId send a subscribe-trade-histories/[instrumentId] command to subscribe to trade history updates. It will initially return a set-trade-histories/[instrumentId] event that contains the most recently executed trades for the requested instrumentId. An append-trade-histories/[instrumentId] event will then be returned for each additional trade executes while the subscription is active.

Note that a maximum of the latest twenty orders only is returned for the requested instrumentId or the latest 20 for all trade history.

The data property is an object keyed by instrumentId, with the following details:

Set trade history Event Schema

Name	Type	Description
[key]		Unique identifier of the instrument
amount	string	Quantity traded
created	string	Time of trade
price	string	Executed price, the last 2 digits are decimal places
side	string	Aggressive side of order (`buy` or `sell`). `auction` is returned as value when trade is a result of an auction

Send a subscribe-transactions command to subscribe to transaction updates. It will return a set-transactions event that contains the last 1000 transactions for the organisation you belong to. Subsequent transactions would also cause a set-transactions event to be returned which will maintain the same data structure and the list of entries would include the new transactions.

The data property is an object with a single key entries which in turn is an array of transaction objects. Each transaction object has the following details:

Set Transaction Event Schema

Name	Type	Description
id	string	Unique identifier of the transaction
organisationId	number	Unique identifier for the organisation associated with the transaction
userId	number	Unique identifier of the user associated with the transaction
accountId	number	Unique identifier for the account
amount	string	For cash accounts - actual monetary value of the transaction where the last two digits are decimal places
		For security accounts - quantity involved in the transaction
referenceId	string	Unique reference to event (where event can be an execution or a notification for a deposit etc.)
created	string	Time of transaction
ledgerType	string	Value is one of `credit` or `debit`
reportType	string	Value can be one of - `commission`, `execution`, `deposit`, `fee`, `coupon`, `manualCorrection`, `interest`, `dividend`, `withdrawal` or `tax`
commissionReference	string	Unique identifier of the commission if applicable
instrumentId	string	Unique identifier of the asset

set-transactions event updates must completely replace the previous state. For example, if your transactions list has the following state:

[ { "id": "1631014099470021", "organisationId": 3, "userId": 5, "accountId": 2786123124, "amount": "1234", "referenceId": "1631014099467372", "created": "1631014099463903", "ledgerType": "credit", "reportType": "execution", "commissionReference": "0", "instrumentId": "7" }, { "id": "1631014099468016", "organisationId": 3, "userId": 5, "accountId": 2786123148, "amount": "121", "referenceId": "1631014099467372", "created": "1631014099463907", "ledgerType": "debit", "reportType": "commission", "commissionReference": "1631014043667348", "instrumentId": "7" } ]

an event to update the list of transactions you have would be in the form:

{ "status": "OK", "action": "set-transactions", "data": { "entries": [ { "id": "1631014364507061", "organisationId": 3, "userId": 5, "accountId": 2786123124, "amount": "109", "referenceId": "1631014364505500", "created": "1631014364499900", "ledgerType": "credit", "reportType": "execution", "commissionReference": "0", "instrumentId": "7" }, { "id": "1631014099470021", "organisationId": 3, "userId": 5, "accountId": 2786123124, "amount": "1234", "referenceId": "1631014099467372", "created": "1631014099463903", "ledgerType": "credit", "reportType": "execution", "commissionReference": "0", "instrumentId": "7" }, { "id": "1631014099468016", "organisationId": 3, "userId": 5, "accountId": 2786123148, "amount": "121", "referenceId": "1631014099467372", "created": "1631014099463907", "ledgerType": "debit", "reportType": "commission", "commissionReference": "1631014043667348", "instrumentId": "7" } ] } }

and the resulting transactions state will be:

[ { "id": "1631014364507061", "organisationId": 3, "userId": 5, "accountId": 2786123124, "amount": "109", "referenceId": "1631014364505500", "created": "1631014364499900", "ledgerType": "credit", "reportType": "execution", "commissionReference": "0", "instrumentId": "7" }, { "id": "1631014099470021", "organisationId": 3, "userId": 5, "accountId": 2786123124, "amount": "1234", "referenceId": "1631014099467372", "created": "1631014099463903", "ledgerType": "credit", "reportType": "execution", "commissionReference": "0", "instrumentId": "7" }, { "id": "1631014099468016", "organisationId": 3, "userId": 5, "accountId": 2786123148, "amount": "121", "referenceId": "1631014099467372", "created": "1631014099463907", "ledgerType": "debit", "reportType": "commission", "commissionReference": "1631014043667348", "instrumentId": "7" } ]
