DateTime Format

All timestamps are returned in ISO 8601 format (UTC).
Example: "2017-04-03T10:20:49.315Z"

Number Format

All finance data, i.e. price, quantity, fee etc., should be arbitrary precision numbers and have a string representation.
Example: "10.2000058"

Pagination

Parameters:

Parameter	Description
limit	Number of results per call Accepted range: 0 - 1000 Default value: 100
offset	Number of results offset Default value: 0
sort	Sort direction Accepted values: `ASC` (ascending order), `DESC` (descending order) Default value: `DESC`
by	Defines filter type Accepted values: `id`, `timestamp`
from	Interval initial value (optional parameter) If filter by `timestamp` is used, then parameter type is `datetime`, otherwise `object id`
till	Interval end value (optional parameter) If filter by `timestamp` is used, then parameter type is `datetime`, otherwise `object id`

RATE LIMITING

Following Rate Limits are applied:

For the Market data, the limit is 100 requests per second for IP;
For Trading, the limit is 100 requests per second for user;
For other requests, including Trading history, the limit is 10 requests per second for user.

Significant excess of the Rate Limits can lead to suspension.

BEST PRACTICES

The Multiexchange API development team strives to bring the best trading experience for API users. This manual contains a set of best practices for using the API as efficiently as possible.

HTTP Persistent Connection

The underlying TCP connection is kept active for multiple requests/responses. Subsequent requests will result in reduced latency as the TCP handshaking process is no longer required.

If you use the HTTP 1.0 client, please ensure it supports the Keep-Alive directive and submit the ''Connection: Keep-Alive'' header with your request.

Keep-Alive is a part of the HTTP 1.1 protocol and enabled by default on compliant clients. However, you will have to ensure your implementation does not set other values as the connection header.

Retrieving and updating account state

Use Streaming API for real-time updates of your orders, trades and any transaction changes.

}

POST /api/2/order
PUT /api/2/order/{clientOrderId}

Price accuracy and quantity

Symbol config contains tickSize parameter which means that price should be divided by tickSize without residue.
quantity should be divided by quantityIncrement without residue.
By default, if strictValidate is not enabled, Server rounds half down price and quantity for tickSize and quantityIncrement.

Example for ETHBTC: tickSize = '0.000001', then price '0.046016' is valid, '0.0460165' is invalid.

Fees

Charged fee is determined in symbol's feeCurrency. Maker-taker fees offer a transaction rebate provideLiquidityRate to those who provide liquidity (the market maker), while charging customers who take that liquidity takeLiquidityRate.

To create buy orders, you must have sufficient balance including fees.
Available balance > price * quantity * (1 + takeLiquidityRate)

Order result status

For orders with timeInForce = IOC or FOK, REST API returns final order state: filled or expired.

If order can be instantly executed, then REST API returns filled or partiallyFilled status in order's info.

Parameters:

Name	Type	Description
clientOrderId	String	Optional parameter If it is skipped, it will be generated by Server. Uniqueness must be guaranteed within a single trading day, including all active orders.
symbol	String	Trading symbol
side	String	Trade side Accepted values: `sell` or `buy`
type	String	Optional parameter Accepted values: `limit`, `market`, `stopLimit`, `stopMarket` Default value: `limit`
timeInForce	String	Optional parameter Accepted values: `GTC`, `IOC`, `FOK`, `Day`, `GTD` Default value: `GDC`
quantity	Number	Order quantity
price	Number	Order price. Required for limit order types
stopPrice	Number	Required for stop-limit orders
expireTime	Datetime	Required for orders with `timeInForce` = `GTD`
strictValidate	Boolean	Price and quantity will be checked for the incrementation within tick size and quantity step. See symbol's `tickSize` and `quantityIncrement`.
postOnly	Boolean	A post-only order is an order that does not remove liquidity. If your post-only order causes a match with a pre-existing order as a taker, then order will be cancelled.

Response: order

Socket API Reference

Use JSON-RPC 2.0 over WebSocket connection as transport.

Request object

{
  "method": "newOrder",
  "params": {
    "clientOrderId": "57d5525562c945448e3cbd559bd068c4",
    "symbol": "ETHBTC",
    "side": "sell",
    "price": "0.059837",
    "quantity": "0.015"
  },
  "id": 123
}

RPC call is represented by sending a Request object to a Server.

The Request object has the following members:

method - a String containing the name of the method to be invoked.
params - a Structured value that holds the parameter values to be used during the invocation of the method.
id - An identifier established by the Client that MUST contain a String, Number, or NULL value if included. If it is not included it is assumed to be a notification. The value SHOULD NOT be Null.

Notification

{
  "jsonrpc": "2.0",
  "method": "updateTrades",
  "params": {
    "data": [
      {
        "id": 54469813,
        "price": "0.054670",
        "quantity": "0.183",
        "side": "buy",
        "timestamp": "2017-10-19T16:34:25.041Z"
      }
    ],
    "symbol": "ETHBTC"
  }
}

A Notification is a Request object without an id member. A Request object (a Notification) signifies the lack of the Client's interest in the corresponding Response object. Therefore no Response objects need to be returned to the Client.

The Notification object has the following members:

method - a string containing the name of the method to be invoked.
params - a structured value holding the parameter values to be used during the method invocation.

Response object

When RPC call is made, the Server MUST reply with a Response, except for Notifications cases.

Server responses for each request. Response on success subscription is true. Example:

{
  "jsonrpc": "2.0",
  "result": true,
  "id": 123
}

Response error

{
  "jsonrpc": "2.0",
  "error": {
    "code": 2001,
    "message": "Symbol not found",
    "description": "Try get /api/2/public/symbol, to get list of all available symbols."
  },
  "id": 123
}

The Response is represented as a single JSON Object, with the following members:

result - this member is REQUIRED on success. This member MUST NOT exist if there was an error during method invocation. The value of this member is determined by the method invoked on the Server.
error - this member is REQUIRED on error. This member MUST NOT exist if there was no error triggered during method invocation. The value for this member MUST be an Object as defined in Error response section.

Socket Market Data

The parameters of requests, responses, and errors correspond to REST, but usage methods are different.
First, you should subscribe for the required data. Then Server will send a full snapshot of the data. After that, Server sends an update notification.

Socket Trading

Trade via socket has major changes compared to REST:

Quickness - time to place new order a bit higher than network latency.
Server notify on any order updates.
FIFO. Your requests are executed on a first-come.

API Sample Code & Libraries

Fetch all public trades

Fetch all trades history for symbol & keep it updated.

General idea: the fetch trades are sorted by ASC from latest id.

import requests
import time
session = requests.session()


def get_trades(symbol_code, from_id):
    return session.get("https://api.bequant.io/api/2/public/trades/%s?sort=ASC&by=id&from=%d&limit=1000" % (symbol_code, from_id)).json()


symbol = 'ETHDAI'
from_trade_id = 1

while True:
    trades = get_trades(symbol, from_trade_id)
    if len(trades) > 0:
        from_trade_id = trades[-1]['id'] + 1
        print('Loaded trades till', trades[-1]['id'], trades[-1]['timestamp'])
        if len(trades) < 1000:
            time.sleep(5)
    else:
        time.sleep(30)

Get trades updated

First version

The fastest way is use the socket API. Subscribe for reports (method subscribeReports) and handle reportType == trade.

Second version

Fetch trades as in the example above but with small changes.

import requests
import time
session = requests.session()
session.auth = ('3ef4a9f8c8bf04bd8f09884b98403eae', '2deb570ab58fd553a4ed3ee249fd2d51')

def get_my_trades(from_id):
    return session.get("https://api.bequant.io/api/2/history/trades?sort=ASC&by=id&limit=100&from=%d" % (from_id)).json()

def get_recent_my_trades():
    return session.get("https://api.bequant.io/api/2/history/trades?sort=DESC&by=id&limit=10").json()

from_trade_id = 0

while True:
    if from_trade_id == 0:
        recent_trades = get_recent_my_trades()
        if len(recent_trades) > 0:
            from_trade_id = recent_trades[0]['id'] + 1
            print('Last recent trade', recent_trades[0])
        else:
            print('You do not have any trades')
    else:
        trades = get_my_trades(from_trade_id)
        if len(trades) > 0:
            from_trade_id = trades[-1]['id'] + 1
            print('new trades', trades)
        else:
            print('No new trades')
    time.sleep(30)

Getting new transactions

The code in the example allows getting all of your new deposits, withdrawals and transfers.

Index - 64-bit integer, that increases on any transaction update. To get all new updates of transactions you will need to request transactions with an index value which is greater than the latest one.

For example, if you have created a withdrawal, then you get an update with a transaction hash and committed status after receiving the required number of confirmations.

import requests
import time
session = requests.session()
session.auth = ('3ef4a9f8c8bf04bd8f09884b98403eae', '2deb570ab58fd553a4ed3ee249fd2d51')

def get_my_transactions(from_index):
    return session.get("https://api.bequant.io/api/2/account/transactions?sort=ASC&by=index&limit=100&from=%d" % (from_index)).json()

def get_recent_my_transactions():
    return session.get("https://api.bequant.io/api/2/account/transactions?sort=DESC&by=index&limit=100").json()

from_index = 0

while True:
    if from_index == 0:
        recent_transactions = get_recent_my_transactions()
        if len(recent_transactions) > 0:
            from_index = recent_transactions[0]['index'] + 1
            print('Last recent trade', recent_transactions[0])
        else:
            print('You do not have any transactions')
    else:
        transactions = get_my_transactions(from_index)
        if len(transactions) > 0:
            from_index = transactions[-1]['index'] + 1
            print('New and Updated transactions', transactions)
        else:
            print('No new updates')
    time.sleep(60)
