Indicator does not work to 30 sec timeframe

[sniper]

I built an indicator that draws a diamond under certain conditions.
It works well to 1, 5 and 15 minutes and also at 15 and 45 seconds but not at 30 seconds.
What could be the problem?
Thanks a lot.

Hello sniper,

Thank you for your post.

Can you provide the indicator file to test on my end? You will find the file in the following directory on your PC: (My) Documents\NinjaTrader 7\bin\Custom\Indicator

What instrument are you testing the 30 second chart and indicator on? Does the indicator have the same issue on any other 30 second chart for other instruments?

Do you see any errors listed in the Log tab of the Control Center?

Found the error :
in protected override void OnBarUpdate()
{
if (CurrentBar < 1 )
return;

I changed 1 with the period counting bars is 21 and now it works fine.

Thank you very much
