Error in backtesting using this code: MarketData.GetBars
12 May 2025, 17:15

Hi,

I have this error during backtesting (version. 5.2.11.39935) :

Error | Failed to get symbol 'EURGBP': Symbol not found or has no quotes.

Info | Not Done with : EURGBP Renko20 at Robots.Test.OnStart() in .cs:line 211 Object reference not set to an instance of an object.

Here is my code:

foreach (var lTimeFrame in mTimeFrames.Keys)
{
	foreach (string lSymbol in mSymbolFrom)
	{
		Bars lBars = MarketData.GetBars(lTimeFrame, lSymbol); //This line cause the error, cause lbars => null after this initialisation
    }
}

FxPro is the broker.

Can you correct this bug ?

Best regards Frank

Hard code it in there as a parameter and see if that works.

eg: MarketData.GetBars(lTimeFrame, “EURGBP”)

If you have a spread-betting account, some times those accounts have slightly different symbol names to indicate they're spread betting.

Thank you for your reply!
Always the same error, also with:
MarketData.GetBars(TimeFrame.Renko20, “EURGBP”)
Do you have a solution ?
Best regards
