Getting error when 3rd previous candle count is used for CLose or Open values

[mtamaku]

Hello:
I am not able to execute strategy as soon as I use Close[2] or Open[2] , last 3rd Candle values to compare with Open or Close of current candle or 2nd last candle 1.

Here is the statement causing issues in the Log.


if (Close[2] < Open[2] && Close[1] > Open[1] && Close[0] > Close[1] && Low[1] < Low[2])
{
Bull_123_Bar = true;
}

Here is the log I get.

Strategy 'A1_M': Error on calling 'OnBarUpdate' method on bar 1: Object reference not set to an instance of an object.
Strategy 'A1_M': Error on calling 'OnBarUpdate' method on bar 1: Object reference not set to an instance of an object.
Strategy 'A1_M': Error on calling 'OnBarUpdate' method on bar 1: Object reference not set to an instance of an object.

Thanks,

I increased the data series to load for 100 days and then I am able to run the strategy.
Is that the fix ?

Hello mtamaku,

If you are using a barsAgo index of 2, you will need to wait until there are 3 bars processed in OnBarUpdate().

if (CurrentBar < 2)
return;
