DrawEllipse("tag1", true, 5, Close[5], 0, Close[0], Color.Blue, Color.Blue, 5);
DrawDot("tag2", true, 0, Low[0] - TickSize, Color.Red);


nothing shows up on the chart.

Hello,
Thank you for your post.

This is happening because there are not enough bars contained in the data series you are accessing. The correct way to structure your OnBarUpdate() would be like this:

if (CurrentBar<5)
return;
DrawEllipse("tag1", true, 5, Close[5], 0, Close[0], Color.Blue, Color.Blue, 5);
DrawDot("tag2", true, 0, Low[0] - TickSize, Color.Red);

This will check how many bars we have seen (CurrentBar) and to exit the OnBarUpdate() method if an insufficient number of bars has been seen.

You may reference the following forum tips page for more information on how to ensure that enough bars have been seen.
