Close[1] not working for me

[bflotrader3]

For some reason when I try to get the previous bar's close value in my indicator, using Close[1], it doesn't work.

To test this I created a new indicator, with one line, and set it to just plot Close[1]. When I do that, nothing is plotted. If I change it to Close[0] it plots as expected.

Here is my code if that helps:

///<summary>
/// This method is used to configure the indicator and is called once before any bar data is loaded.
///</summary>
protectedoverridevoid Initialize()
{
Add(new Plot(Color.FromKnownColor(KnownColor.Sienna), PlotStyle.Line, "PChange"));
Overlay = false;
}
///<summary>
/// Called on each bar update event (incoming tick)
///</summary>
protectedoverridevoid OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
PChange.Set(Close[1]);
}

Look in your log and you should see an error about an index being out of bounds.

You need to escape your first bar, as it does not exist when the code first runs. Try the suggestion in this thread (and numerous others in the forum).

Hello bflotrader3,

Thank you for your post.

The bar data is being referenced but does not exist, you will need to ensure enough bars are loaded before accessing that data. Something like if(CurrentBar <= BarsRequired) return;

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