Failed to call 'Add' method

[shayhz]

Hi,

I'm writing a new strategy that I run on 5 minute.
I want to use also daily data in the strategy, so I added "Add(PeriodType.Day, 1);" in the "Initialize" method.

The problem is that I get the below errors:

Default Failed to call 'Add' method: Cbi.Bars.Add: volume value (-210) must be greater than 0

Hello shayhz,

Thank you for your post.

You will need to make sure you have enough bars in your chart before accessing them. For information on making sure you have enough bars on your chart before accessing them please visit the following link: http://www.ninjatrader.com/support/f...ead.php?t=3170

Please let me know if I may be of further assistance.

I've added the check using "CurrentBar", but I still get the below error.
I think it's related to my use of the daily data, while the strategy is running on 5 min data.
example of my use is: Closes[1][1]

Any thoughts ?

Hello shayhz,

Thank you for your response.

Please try the following:

if(CurrentBar < BarsRequired)
return;

You need to check all bar series, not just CurrentBar.
