OnBarUpdate or Plot Method Error

[nedrob519]

I have an indicator that plots 10 different lines. When I exit from the indicator parameters window, I get an error "Please check the OnBarUpdate or the Plot method. Index was outside the bounds of the array." And the levels are not drawn on the chart.

However, if I press F5 on the chart, all the levels draw as they should and there are no errors.

I have all my code wrapped in try-catch blocks and those are not catching any errors.

Any ideas? I have been using my indicator for months now and never got this error before. It seems to have just started happening in the last couple of days.

Thanks!

Hello nedrob519,

Thank you for your note.

This would point to a value being set or accessed outside of the possible range. Are you ensuring you have enough bars to calculate the values?

Yes, I check for currentbars: if (CurrentBars[0] < 20 || CurrentBars[1] < 20) return;

As I said, if I press F5 to refresh the chart, everything is perfect and there are no errors.

The only time I get the error is when I exit the Indicator's Parameter window. The error is in the log and the plots don't plot. And, none of my try catch blocks are executed when exiting the parameter window also.

I would think that if there really was this error, pressing F5 to refresh the chart would not work.

So there must be a different execution path that is at work, right?

Here is the Property Get is am using.

[Browsable(false)]
[XmlIgnore()]
public DataSeries High
{
get { return Values[1]; }
}

Anything here?

Hello nedrob519,

That would not be the case. Compiling does not run the code over a data set.

Not F5 in the compiler. You misunderstood.

If you press F5 on the CHART, it reloads the indicators. That works 100% of the time.

So - it doesn't work when closing the indicator's parameter window. But it DOES work when pressing F5 on the CHART to re-load the indicator.

It should work in both places or not at all unless there is something different about those 2 execution paths.

Thanks,

Both should load in the same manner. Please send me your log and trace files for today so that I may look into what occurred.
