Found out my fault

Now I found out! Everything is fine, just the timestamp is the starting and not the ending timestamp of the bar so i received the 10.00am bar that is actually the last from 10.00am to 10.30am! I apologize, it is mentioned in the documentation here 

Thank you for your kind support!

Antonio

Debugging

Everything seems right in python code:

    def trendbarsResponseCallback(self, result):

        # print("\nTrendbars received")

        trendbars = Protobuf.extract(result)

        print(f"Trendabars received: {trendbars}")

        barsData = list(map(self.transformTrendbar, trendbars.trendbar))

        #barsData = list(map(self.transformTrendbar, result))

        barsData = {"bars": barsData}

        return json.dumps(barsData)

    def sendProtoOAGetTrendbarsReq(self,

                                currentAccountId: int,

                                symbolId: int,

                                timeframe: str,

                                since_ms: int,

                                until_ms: int):

        request = ProtoOAGetTrendbarsReq()

        request.symbolId = symbolId

        request.ctidTraderAccountId = currentAccountId

        request.period = self.timeframe_to_proto_period(timeframe)

        request.fromTimestamp = since_ms

        request.toTimestamp = until_ms

        request.count = 3

        print(f"Requesting trendbars symbolId: {request.symbolId}")

        print(f"Requesting trendbars period: {request.period}")

        print(f"Requesting trendbars fromTimestamp: {request.fromTimestamp}")

        print(f"Requesting trendbars toTimestamp: {request.toTimestamp}")

        print(f"Requesting trendbars count: {request.count}")

        deferred = self.client.send(request)

        deferred.addCallbacks(self.trendbarsResponseCallback, onError)

        return deferred

this is are logs showed 

sending with toTimestamp 1689237969000 that is actually 10:46am

the last bar received is at 28153920 minutes that is 1689235200 that is 10.00am

Hi there,

Indeed. Does this happen on all symbols? How can we reproduce it? Symbol? Broker?

It happens on all symbols, using cTrader Pepperstone. If necessary I'll extract a snippet from the code. Basically to reproduce I do the ProtoOAGetTrendbarsReq with toTimestamp = int(calendar.timegm(datetime.datetime.utcnow().utctimetuple())) * 1000

Thanks

Hi there,

ProtoOAGetTrendbarsReq returns only historical data. Use ProtoOASubscribeLiveTrendbarReq to get the current live trendbar.

Sorry for continue asking, but for example, when is 10.02AM on timeframe 30 minutes, I thought 9.30AM-10.00AM was an historic bar and 10.00AM-10.02AM is the live bar. Isn't it correct?
