I'm trying to put YM's overnight session's high and low on my 24 hour flex chart using the High/Low for Time Period study.

My Start Time is 16:15:00 and the End Time is 09:29:59. I'm using the draw style of Subgraph Name and Value Labels Only because I only want to see the ONH or ONL at the right edge (the Short Name I've assigned).

This works just fine until around 10:17 EST when the text vanishes. This happens every day.

Any ideas on how to keep it from vanishing?

Same here.
