Custom Indicator using Stochastics() values

[marcusplexus]

Hi,

I am unsuccessful at creating a custom indicator which uses compared Stochastics values. In the protected override void OnBarUpdate() section I do the following comparison in order to print a down arrow on my charts. This doesn't work.

if ( Stochastics(7,14,3).K[0] < Stochastics(7,14,3).K[1] )

Troubleshooting reveals that...

if ( Stochastics(7,14,3).K[0] < 79 ) will print arrows on the charts.
if ( Stochastics(7,14,3).K[1] < 79 ) won't print arrows on the charts.

Looks like Ninjascript completely ignores the condition when the %K parameter is not set to .K[0]

How do I go about making this work?

MarcusPlexus, please add this line to the very beginning of your OnBarUpdate() section:

protected override void OnBarUpdate()
{
    if (CurrentBar < 2)
        return;
    
    // all your other code goes here
}

I believe you are running into an issue where there actually aren't enough bars on the chart, and if so, there should be an error in the logs (right-most tab of Control Center) about accessing an invalid index.

Yes!!!!!!! That was it!

Many thanks!
