Plotpaintbar only once?

["aiiishot" <aiiishot@xxxxxxxxx>]

Hi all,
can you please help me with the following;  how do I paint a bar only once
in the day, when my criteria is met?  For example, when using the following
EeasyLanguage code "If close = 30 then Plotpaintbar(High,Low, "myprice");"
How can I make it so only the first bar that meets this criteria is painted
on my chart, and not all the bars that also are 30 in price.

TIA,
Michael
