Bug? Backend Failure? Cannot get NQc1 / NQU0 bid/ask ticks on Sep 4 between 8:21 and 14:52...

Hello @Chon11201120

Fully agree with @Alex Putkov.1 that the raw request should work and return 50k results. Suspecting two issues, from looking at the code.

Is a large request, may take long, would test it first on the same request, shortening the interval to a much smaller one, to see if you get the result quickly. For example:

request = timeSeries.SetupDataRequest("JPY=")
                .WithView("BID")
                .WithAllFields()
                .From(new DateTime(2020, 8, 4, 8, 21, 0))
                .To(new DateTime(2020, 8, 4, 9, 52, 0))
                 .WithInterval(CommonInterval.Tick)
                .OnDataReceived(DataReceivedCallback2)
                .WithTimeZone(TimezoneType.Instrument)
                .CreateAndSend();
        }

Not every tick has a volume. HasVolume results in false. Which would be why the callback may not print any results. Would try to see the results first, then tune the callback, for example:

  private void DataReceivedCallback2(DataChunk chunk)
        {
            foreach (ITickData tick in chunk.Records.ToTickRecords())
            {
                Console.WriteLine("Received Ticks");
                if (tick.Timestamp.HasValue && tick.Value.HasValue  )
                {
                    Console.WriteLine(
                        "time={0}: val={1} vol={2} ",
                        tick.Timestamp.Value,
                       tick.Value,
                        tick.Volume
                    );
                };
            }

Once you get the result back (?), may prefer to cut up the request interval into several smaller sub-intervals, so you can meet your requirement, and get the results back quickly.
