How to Handle BarsRequest Errors?

[NinjaTrader_Jesse]

Hello NtFan,

Thank you for the post.

Do you have a specific sample that demonstrates the problem? If you can copy/paste the total BarsRequest logic you used into a test indicator and attach that it would be helpful. Also what are the specific steps to see the error? Are you running this against an instrument that does not exist or what is the specific situation? If the case is that this is an error and it is not being reported as an error I can likely report that to development with a sample/steps to see that.

I look forward to being of further assistance.

I'm using BarsRequest in an Add On procedure that I've developed, and I'm handling BarsRequest errors as demonstrated in the NT8 Help Guide topic for BarsRequest, as in...

barsRequest.Request(new Action<BarsRequest, ErrorCode, string>((bars, errorCode, errorMessage) =>
{
if (errorCode != ErrorCode.NoError)
{
// Handle any errors in requesting bars here
NinjaTrader.Code.Output.Process(string.Format("Err or on requesting bars: {0}, {1}",
errorCode, errorMessage), PrintTo.OutputTab1);
return;
}

etc.

I've discovered that this approach to handling errors produced by the Request method doesn't work. It doesn't work, because when the Request method encounters an error the "if (errorCode != ErrorCode.NoError)" code snippet doesn't execute. Instead, NT immediately issues an error that reads like "Error on requesting bars series: 'The instrument for which you requested data is invalid.'" and NT exits the procedure. So, might you recommend another approach for trapping and handling errors produced by the Request method?
