Mysterious Out Of Range Exception

[anon84]

Getting out of range exception when calling these from a button:

Print(Highs[1].GetValueAt(CurrentBars[1] - HighestBar(Highs[1],6)));
Print(Highs[1][HighestBar(Highs[1],6)]);

Works in OnBarUpdate.

It's not related to HighestBar. The same error happens when I try:

Print(APZ(BarsArray[1],1,20).Upper[1]);

but strangely if changed to Upper[0] then no error!

Barebones example script attached.

Thanks.

Hello anon84,

That would be expected, a button event is not a NinjaScript bar close event. You need to use TriggerCustomEvent inside button events.

TriggerCustomEvent(o =>
{
    // your code here
}, null);

Excellent, thanks!
