Why Is Nothing Displaying?

[josh18955]

I took the code from ninja trader syntax. Just learning to try and add boxes to my chart, but for some reason whenever I add the indicator to the chart no box is plotted. Visible is selected, overlay true, etc.

All I want to do is plot a box a certain amount of ticks away from close. Feels so simple but nothing I do is working

Hello, thanks for writing in. Always first check the Log tab of the Control Center when you are testing a script and it does not work as expected. There will be a message there stating the lookback period tried to access 10 bars back but there are less than 10 bars on the chart at the time. Add this to the top of OnBarUpdate to make sure you can access Low[10] before processing the Draw command:

if(CurrentBar < 10)
return;
