Object reference not set to an instance of an object

[Sleeping Troll]

I always have a tough time finding these.
This is the code that throws the error:

          while(CanNumber < CanCount)
            {
                TOI = Time[0];
                barsAgo=GetBar(new DateTime(TOI.Year,01,01,00,00,00));
                SubjBar = HighestBar(High,barsAgo);
                Canhigh[CanNumber] = Math.Round(High[SubjBar],2);
                SubjBar = LowestBar(Low,barsAgo);
                Canlow[CanNumber] = Math.Round(Low[SubjBar],2);
                Canopen[CanNumber] = Math.Round(Open[barsAgo],2);
                Canclose[CanNumber] = Math.Round(Close[0],2);
                CanNumber = CanNumber +1;
            }

Any ideas?

P.S.

        private int CanCount = 1;
        private int CanNumber = 0;

I did stumble upon a nifty way to isolate these errors. Precede each section in question with:
if (CurrentBar < x)return;
Use a unique x for each section and the error will tell you which section is throwing the error.

if (CurrentBar < 1)return;
while(CanNumber < CanCount)
{
if (CurrentBar < 2)return;
TOI = Time[0];
if (CurrentBar < 3)return;
barsAgo=GetBar(new DateTime(TOI.Year,01,01,00,00,00));
if (CurrentBar < 4)return;
SubjBar = HighestBar(High,barsAgo);
if (CurrentBar < 5)return;
high[CanNumber] = High[SubjBar];
if (CurrentBar < 6)return;
SubjBar = LowestBar(Low,barsAgo);
if (CurrentBar < 7)return;
low[CanNumber] = Low[SubjBar];
if (CurrentBar < 8)return;
open[CanNumber] = Open[barsAgo];
if (CurrentBar < 9)return;
close[CanNumber] = Close[0];
if (CurrentBar < 10)return;
CanNumber++;
}

5 is throwing error...

Hello,

Did you find the error?

You also may want to try the try catch block:
