Delta close not showing in SubscribeLiveTrendBarReq

Hey, I'm trying to use this code to get the trend bar information so i can have live bar closes so my indicator can be updated.

The problem i'm facing is that the response i'm getting doesnt show delta.close. I could use the delta.open of the next bar but its not ideal as sometimes the close of the previous bar isnt the same as the open of the current bar.

credentialsFile = open("credentials-dev.json")

credentials = json.load(credentialsFile)

 

host = EndPoints.PROTOBUF_LIVE_HOST if credentials["HostType"].lower() == "live" else EndPoints.PROTOBUF_DEMO_HOST

client = Client(host, EndPoints.PROTOBUF_PORT, TcpProtocol)

 

symbolName = "GBPUSD"

 

def sendProtoOASubscribeLiveTrendbarReq(result):

    request = ProtoOASubscribeLiveTrendbarReq()

    request.symbolId = 2

    request.ctidTraderAccountId = credentials["AccountId"]

    request.period = ProtoOATrendbarPeriod.M1

    deferred = client.send(request)

    deferred.addErrback(onError)

 

def sendProtoOASubscribeSpotsReq(result):

    symbols = Protobuf.extract(result)

    global symbolName

    symbolsFilterResult = list(filter(lambda symbol: symbol.symbolName == symbolName, symbols.symbol))

    if len(symbolsFilterResult) == 0:

        raise Exception(f"There is symbol that matches to your defined symbol name: {symbolName}")

    elif len(symbolsFilterResult) > 1:

        raise Exception(f"More than one symbol matched with your defined symbol name: {symbolName}, match result: {symbolsFilterResult}")

    symbol = symbolsFilterResult[0]

    symbolId = symbol.symbolId

 

    timeInSeconds = 2

    subscribeToSpotTimestamp = False

    clientMsgId = None

 

    request = ProtoOASubscribeSpotsReq()

    request.ctidTraderAccountId = credentials["AccountId"]

    request.symbolId.append(int(symbolId))

    request.subscribeToSpotTimestamp = subscribeToSpotTimestamp if type(subscribeToSpotTimestamp) is bool else bool(subscribeToSpotTimestamp)

    deferred = client.send(request, clientMsgId = clientMsgId)

    deferred.addCallbacks(sendProtoOASubscribeLiveTrendbarReq, onError)

    #deferred.addErrback(onError)

    #reactor.callLater(int(timeInSeconds), sendProtoOAUnsubscribeSpotsReq, symbolId)

 

def accountAuthResponseCallback(result):

    print("\nAccount authenticated")

    request = ProtoOASymbolsListReq()

    request.ctidTraderAccountId = credentials["AccountId"]

    request.includeArchivedSymbols = False

    deferred = client.send(request)

    deferred.addCallbacks(sendProtoOASubscribeSpotsReq, onError)

   

def applicationAuthResponseCallback(result):

    print("\nApplication authenticated")

    request = ProtoOAAccountAuthReq()

    request.ctidTraderAccountId = credentials["AccountId"]

    request.accessToken = credentials["AccessToken"]

    deferred = client.send(request)

    deferred.addCallbacks(accountAuthResponseCallback, onError)   

 

def onError(client, failure): # Call back for errors

    print("\nMessage Error: ", failure)

 

def disconnected(client, reason): # Callback for client disconnection

    print("\nDisconnected: ", reason)

 

def onMessageReceived(client, message): # Callback for receiving all messages

    if message.payloadType in [ ProtoHeartbeatEvent().payloadType, ProtoOAAccountAuthRes().payloadType, ProtoOAApplicationAuthRes().payloadType, ProtoOASymbolsListRes().payloadType, ProtoOAGetTrendbarsRes().payloadType]:

        return

   

    m = Protobuf.extract(message)

    with open('test.txt','a') as file:

        file.write(str(m))

   

def connected(client): # Callback for client connection

    print("\nConnected")

    request = ProtoOAApplicationAuthReq()

    request.clientId = credentials["ClientId"]

    request.clientSecret = credentials["Secret"]

    deferred = client.send(request)

    deferred.addCallbacks(applicationAuthResponseCallback, onError)

   

# Setting optional client callbacks

client.setConnectedCallback(connected)

client.setDisconnectedCallback(disconnected)

client.setMessageReceivedCallback(onMessageReceived)

 

# Starting the client service

client.startService()

# Run Twisted reactor, we imported it earlier

reactor.run()

And what i'm getting as response is this

ctidTraderAccountId: 22367191
symbolId: 2
bid: 118347
ask: 118349
trendbar {
  volume: 234
  period: M1
  low: 118321
  deltaOpen: 6
  deltaHigh: 42
  utcTimestampInMinutes: 27971363
}

Is there any way to show delta.close? Thanks in advance.
