Indicator does not plot?

[Forex99]

Hello,

The code below compiles ok but does not plot anything when placed on a chart. Where do I go wrong?

Anyone?

Regards,

Dennis

Hello,
Thank you for your post.
Are you receiving any errors in the log tab on the control center?
I look forward to your reply.

[arbuthnot]

Could it be simply that you you haven't put:

if (CurrentBar < N) // N = Max period value of any variable
return;

I've done this so many times. If this declaration isn't made, the ind won't plot.

[NinjaTrader_CodyB]

Hello,
This indicates that there are not enough bars on the chart for the indicator to run.
protected override void OnBarUpdate()
{
if (CurrentBar < 1)
return;

if (Close[0] > Close[1])
// Do something
}
I have included a link to a forum post that explains this topic thoroughly. http://www.ninjatrader.com/support/f...ead.php?t=3170
If there is anything else I can assist with please let me know.

that indeed solves the problem...thank you...
