Bars.GetDayBar(1).Open - How to assign it to a variable

[nurushaik]

Bars.GetDayBar(1).Open - I'm able to print the value in out put window, when trying to assign this value to a variable getting error

Error on calling 'OnBarUpdate' method on bar 0: Object reference not set to an instance of an object.

Appreciate your inputs on this.

Hello nurushaik,

There is a sample of how to use this method in the help guide, the error you are getting is caused by not checking for null like the help guide shows:

Hello Jesse,

I've checked the link,
i'm able to print the values as mentioned in the help guide:
Print( Bars.GetDayBar(1).Open.ToString () + " " + Bars.GetDayBar(1).High + " " + Bars.GetDayBar(1).Low );

when i'm trying to assign these values to a variable then i'm getting error...

double Op_Price = Bars.GetDayBar(1).Open;

Overall my goal is to perform and store/leverage the Bars.GetDayBar(1).Open - Bars.GetDayBar(1).Low values ...

is there any way I can assign or compute above and use in...

thanks in advance.

Hello nurushaik,

The code you have shown is valid, the error you mentioned in post 1 is specifically because you don't have a null check condition surrounding that code.

  if(Bars.GetDayBar(1) != null)
{
    //use your code here
}

Hello Jesse,

That's what I did. still throwing errors.

1.PNG = working fine.. (only used with print)
2.PNG = error ... ( when tried to assign to a variable).

Hello nurushaik,

The if condition you have checking for null is not valid, you have the condition terminating after your print with the closing brace }

The lines after your print are outside the null check condition.

Thanks Jessy. You are correct.

My bad, I didn't noticed.

It works now.
