array values from indicator are "0"

[Sleeping Troll]

I am pulling array vars from an indicator, I have checked the values by printing them from the indicator and they are valid, but I am getting "index was outside the bounds of the array" here is the line:

 
[FONT=Courier New][SIZE=2][COLOR=#008000][FONT=Courier New][SIZE=2][COLOR=#008000][FONT=Courier New][SIZE=2][COLOR=#008000][COLOR=black]macd[CanNumber] = Ladders().macd[CanNumber];[/COLOR][/COLOR][/SIZE][/FONT]
[COLOR=#008000][SIZE=2][FONT=Courier New][COLOR=black]macdAvg[CanNumber] = Ladders().macdAvg[CanNumber];[/COLOR][/FONT][/SIZE]
[SIZE=2][FONT=Courier New][COLOR=black]Upper[CanNumber] = Ladders().Upper[CanNumber];[/COLOR][/FONT][/SIZE]
[/COLOR][/COLOR][/SIZE][/FONT][/COLOR][/SIZE][/FONT][FONT=Courier New][SIZE=2][FONT=Courier New][SIZE=2]Lower[CanNumber] = Ladders().Lower[CanNumber];[/SIZE][/FONT]
[/SIZE][/FONT]

This is where the vars are assigned in the indicator:

 
macd[CanNumber] = fastEma[0] - slowEma[0];
macdAvg[CanNumber] = (2.0 / (1 + Smooth[CanNumber])) * macd[CanNumber] + (1 - (2.0 / (1 + Smooth[CanNumber]))) * Avg[1];
 
Upper[CanNumber] = macd[CanNumber] + StdDev(20)[0];
Lower[CanNumber] = macd[CanNumber] + StdDev(20)[0];

This is my first go at pulling array vars from another class,
What am I missing?

Sleeping Troll, please make sure in your code that when you are accessing an array you are accessing a value that actually exists. For example, if you were to try and grab the value for three bars ago on the first bar of the chart (left-most bar), you would get the "index is out of the bounds of the array" error because the data doesn't exist yet.

You might want to add a simple return if there aren't enough bars and see if that solves the problem:

if (CurrentBar < 2)
   return;

In my Strategy class and my Indicator classI use both:

if (Historical)return;
if (CurrentBar < 20)return;


Same error, I appreciate the response late on a Sunday evening though!

Without seeing the full code, is CanNumber also satisfied by your 20 bars check? To debug it would be best to simplify as much as possible and then work try and catch concepts in to 'hunt' it down - http://www.ninjatrader-support2.com/...ead.php?t=9825
