Problems with Dataloader example

Postby FB2013 » 22 Apr 2013

Hello i am trying to write a multi time frame average indicator.

I am very happy that the DataLoader functionality is explained very detailed in the MC.Net Programming Guide. But i encountered some problems.

The used code part for determining the Data Range within the example produces an exception within VisualStudio Express Debuger saying SHE Exception.

Code: Select all

DataRequest _DataRequest = new DataRequest();
_DataRequest.RequestType = DataRequestType.BarsBack;
_DataRequest.Count = Bars.FullSymbolData.Count;
Request.Range = _DataRequest;
Request.QuoteField
Another problem i encounter right now is, when i use the following code for Data Range.

Code: Select all

Request.Range = DataRequest.CreateBarsBack(DateTime.Now,100);
No Data is Delivered when i use it within the attached source code, which should create four averages on a tick chart using daily and 15 minute data as input.

Hope somebody has a good idea what i made wrong.

Please do not care about
the

Code: Select all

CalcAverage();
PlotValues();
those are not yet implemented. And there still has to be done some logic when to calculate the average and how to plot the data.

Hello FB2013,

This issue has been confirmed. It will be fixed in the next version of MultiCharts .Net.
Another problem i encounter right now is, when i use the following code for Data Range. No Data is Delivered when i use it within the attached source code, which should create four averages on a tick chart using daily and 15 minute data as input.
The issue with BarsBack and DaysBack requests not returning data has been confirmed as well. As a workaround you can use FromTo request that works ok.
