FIX Protocol Specification

FIX Protocol can be implemented using QuickFIX open source engine，please refer to ：QuickFIX

The following language is supported ：

Configuration for quickfix

quickfix configuration ：

[default]
ConnectionType=initiator
SenderCompID=ST-00000001
TargetCompID=APIFINY
SocketConnectHost=fix.api.apifiny.com
StartTime=00:00:00
EndTime=00:00:00
HeartBtInt=30
ReconnectInterval=5
UseDataDictionary=Y
ResetSeqNumFlag=Y
ResetOnLogon=Y
ResetOnLogout=Y
ResetOnDisconnect=Y

[session]
BeginString=FIX.4.2
SocketConnectPort=443

There has an optional sample configuration for login using quickfix. Fix endpoint is: fix.api.apifiny.com:443

Below is an example using Python.

Logon

 def toAdmin(self, message, sessionID):
        if message.getHeader().getField(35) is "A":
            key = 'XXXX'
            signature = get_signature('new_gbbo_order', 'ST-00000015', 'STA-00000015','STA-00000015', key)
            message.setField(fix.RawDataLength(len(signature)))
            message.setField(fix.RawData(signature))
        ...

get_signature is as following：

def get_signature(method, account_id, secret_key_id, params, secret_key):
    now = datetime.datetime.now()
    expect_time = now + datetime.timedelta(seconds=30)
    params_json_string = json.dumps(params) if isinstance(params, dict) else params
    digest = hashlib.sha256(params_json_string.encode()).hexdigest()
    signature = jwt.encode({
        'accountId': account_id,
        'secretKeyId': secret_key_id,
        'digest': digest,
        'method': method,
        'exp': int(expect_time.timestamp()),
    }
        , secret_key)
    # print(str(signature, encoding='utf-8'))
    return str(signature, encoding='utf-8')

Add JWT encrypted token in toAdmin.

Users of the FIX API will have to apply a seperate set of API Access Key, please contact BD team to apply, our team will get back to you within 1 working day.

New Order

    msg = quickfix42.NewOrderSingle()
    msg.setField(fix.ClOrdID(order_id)) # generated order id：00000015+13digt time stamp + 3 digit random number
    msg.setField(fix.Symbol(symbol)) # symbol:BTCUSDT
    msg.setField(fix.HandlInst('1'))
    msg.setField(fix.OrdType(fix.OrdType_LIMIT)) # OrdType：limit
    msg.setField(fix.TransactTime())
    msg.setField(fix.Side(side))
    msg.setField(fix.Price(price))
    msg.setField(fix.Account(account_id))
    msg.setField(fix.OrderQty(qty))
    msg.setField(fix.SecurityExchange("GBBO"))
    msg.setField(fix.Text("new Order"))
    quickfix.Session.sendToTarget(msg, application.sessionID)

New Order message is following in ：

Cancel Order

    msg = quickfix42.OrderCancelRequest()
    msg.setField(fix.OrigClOrdID(order_id))
    msg.setField(fix.ClOrdID(order_id))

    msg.setField(fix.TransactTime())
    msg.setField(fix.Side(side))
    msg.setField(fix.Account(account_id))
    msg.setField(fix.Text("Cancel Order"))
