Starter Coding Indicator Help

[stockgoblin]

Hi!

I thought for my first indicator I'd do something simple like connecting similar candlesticks with an extended line or ray (what's the diff?). I'm getting there but still having problems.


- I need to have the ray draw only when the currentbar is open=close
- The code doesn't like my (Math.Abs(High(0) == Close(0)) anywhere I put it

- There's something wrong in the calculation of the barsago I think

Anyway, any help is appreciated

stockgoblin,

Thanks for the post. Extended lines extend in both directions, a ray only one direction. To connect two points, a line seems more appropriate than either of these.

Generally we don't offer code debugging but I gave your script a quick run here. I see a line drawn on the chart, so it's doing something. May need to refine the statements for what you're going for. First place I'd look is your EndBarsAgo for your line. You have it set to CurrentBar, which means it's drawing that point always at the first bar in the series.

- The code doesn't like my (Math.Abs(Open(0) == Close(0)) anywhere I put it

You need brackets (not parentheses) for bar indexes, like used in other places in your code.

For debugging in NinjaScript, use plenty of Print() statements to check all values. Since each historical OnBarUpdate() belongs with a specific bar, include CurrentBar to track values along with their bar index. Additional help for debugging is available here:
