real-time indicator question

[john hamon <jhamon@xxxxxxxxxxx>]

all,

i have an indicator that paints bars daily bars, rather than using a
paintbar study, to give me more control over their appearance.  as generous
people on this list taught me, it has to "paint" the O,H,L,C separately,
based upon conditions.  

the problem is this: my the conditions that cause the indictor to paint the
bar might come and go intraday, and yet after they've changed, the Open
remains painted.  my interpretation is that once the Open is painted it is
never repainted, yet i have the indicator set to update every tick.

are there some other precautions that you have to take to make sure that an
indicator gets re-evaluated periodically intraday, or do you have to clear
everything periodically and repaint, or simply put: does anybody know how to
make this work?

thanks for your help,

jh
