There are several ways in which you can achieve this:
+ Create your own bulk request class; You can use the attached file as an example:bulkdatarequestcs.txt . The initialisation routine will look like this:
new BulkDataRequestSetup() .WithRics("LCOc1", ".SPX") .WithFields("CLOSE", "TIMESTAMP") .WithInterval(new Interval(IntervalType.Daily, 1)) .WithNumberOfPoints(100) .OnDataReceived(DataReceivedCallback) .OnStatusUpdated(StatusUpdatedCallback) .CreateAndSend();
+ Reuse the same request object; after you received (chunk.isLast == true) in your DataReceivedCallback event, you can set up and send the next request, i.e. chain them.

I tried to access several Rics with your reference code, but I only get the first one "AUD=" rics' 24 ticks' data back, then the program stopped.
Would you please help to check why? the following is my code.
BulkDataRequestSettings RequestSettings = new BulkDataRequestSettings();List<String> field_list = new List<string>();List<String> rics_list = new List<string>();RequestSettings.View = "BID";rics_list.Add("AUD=");rics_list.Add("AUDON =");rics_list.Add("AUDSW =");field_list.Add("CLOSE");field_list.Add("TIMESTAMP");RequestSettings.Rics = rics_list;RequestSettings.Fields = field_list;RequestSettings.From = new DateTime(2016, 9, 7, 15, 0, 0);RequestSettings.To = new DateTime(2016, 9, 8, 15, 0, 0);RequestSettings.Interval= CommonInterval.Intraday60Minutes;RequestSettings.TimeZone = TimezoneType.GMT;BulkDataRequest Request = new BulkDataRequest(RequestSettings);Request.Send();
get rid of the space preceeding the equal sign, e.g., "AUDON=" not AUDON ="
What should I do if I want get multiple views at the same time, i.e. BID and ASK ?
Is it the same way as @Zhenya Kovalyov suggested?
If you just want close bid and ask, you can get them both from the view named NDA_RAW. But if you need open, high, low, close for bid and ask, you have to retrieve them separately for bid and ask, as the API only allows to query one view at a time.
