CrossAbove() with incompatible plots

[GeorgeW]

Hello,

I have a Moving Average plot on my chart, and another plot based on Volume. The scale values of both are incompatible. Is it possible to use CrossAbove() or CrossBelow() when the Maths values are incompatible? I can see the crosses on the chart, and I have set it up in an indicator to alert me when the crosses occur. The indicator compiled, but when I try to add it to a chart, the chart freezes. So can CrossAbove() CrossBelow() recognise visible crosses, or does it need Mathematical crosses?

Thank you.

Hello GeorgeW,

Thanks for your post.

Ninjascript's CrossAbove() or CrossBelow() would only function if they mathematically cross.
