What does this error mean ?

Hi ninjas,

I've been doing certain backtest and all running ok, but weirdly whenever I try to go to recent days, NT gives me this error:

Error on calling 'OnBarUpdate' method for strategy ' ( any xxxxxx indentifier )': Function does not accept floating point Not-a-Number values.

I know it's difficult for you to spot it exactly, but at least could you give me some hint where to find the bug? because it's hard to see this strategy running fine in other dates. It seems to have with BarInProgress, not sure though

Thanks in advance

Hi pstrusi,

The best way to find it is to start adding prints to your code.

I like to print the bar time and a number so i can recognize the prints.

Basically i just look for the last print before the error and try and get it closer and closer.

Print("1 "+Time[0]);

The issue looks to be coming from a method call that is being supplied a value that is NaN.

Hi Chelsea, thanks for your answer but I've just "solved" using a Math.Round for a floating point calculations and it seems to work well now.

If I had any further problems and not be able to know, I'll put it here as headache :-)
