It seems TimeNum() only works correctly in time based charts. In a
non-time based chart like Range chart, it may or may not return
desired result. For example,
rth_open = ValueWhen(TimeNum() == 93000, Open);
this will only return the Open price if you happend to have a bar
starting at 9:30, this usually is not the case in a non time based
chart.
It seems also time compress functions only work with internal time
based array.
If anyone has any differet views, please correct me and help out.
